Do -it -yourself polypropylene pipe instructions

Are you trying to improve the insulation or the heating system in your house? Improving your home’s energy efficiency can have a big impact, regardless of whether you have to deal with harsh winters or skyrocketing energy costs. Adding polypropylene pipes to your heating system is one well-liked upgrade. With easy-to-follow step-by-step instructions, we’ll take you through the installation of polypropylene pipes in your house in this guide.

The resilience, adaptability, and simplicity of installation of polypropylene pipes have made them more and more popular in recent years. Polypropylene pipes are perfect for use in heating systems because they are resistant to rust and corrosion, unlike traditional metal pipes. They also require less time and effort to install because they are lightweight and easily maneuverable.

Ensure that you have all the required tools and materials before starting the installation process. Polypropylene pipes, fittings, a heat fusion tool, a pipe cutter, and a deburring tool are required. Additionally, it’s imperative that you comprehend the heating system in your house as well as the location of the pipe installation.

After obtaining all necessary materials, you can start the installation process by getting the pipes and fittings ready. Using a pipe cutter, begin by cutting the pipes to the required length, being careful to make clean, straight cuts. Next, as these can obstruct the fusion process, use a deburring tool to remove any burrs or rough edges from the pipe ends that have been cut.

Now that the pipes and fittings are ready, you can start using a heat fusion tool to connect them. In order to forge a solid, long-lasting bond, heat fusion entails heating the ends of the pipes and fittings to a predetermined temperature before pressing them together. Make sure you reach the right temperature and fusion time for a secure connection by carefully following the manufacturer’s instructions for your heat fusion tool.

You can install the pipes and fittings in your home’s heating system after they have fused together. Make sure the pipes are positioned properly and that the proper hangers or brackets are used to hold them in place. Before completing the installation process, test the system one last time to make sure everything is operating as it should.

You can upgrade the heating system and increase the energy efficiency of your house by following these do-it-yourself polypropylene pipe instructions. With the correct supplies, equipment, and know-how, anyone can take on this project and reap the rewards of a more economical and comfortable house.

Closed and open installation of a water supply of polypropylene

The first step in arranging the polypropylene water supply by hand is to prepare the main scheme. Use a piece of paper and a handle or a 3D editor to create a plan. D. First, list and arrange all of the appliances that use water, such as the washing machine, bathtub, shower, and taps. Next, add hot and cold water sources to the diagram. These can be risers or a private home’s heating boiler. Finish creating the plan that will list the sources of the hot and cold water supplies that consumers receive.

Pipeline installation that is closed

Next, you need to determine the best way to lay the polypropylene pipe. There are two methods for implementing it: closed and open. According to the first, all of the water supply lines will be "hidden" behind the room’s exterior décor. To do this, the walls of the home or apartment must be removed, and polypropylene pipes must be installed in the created channels. The following are the benefits of the closed installation circuit.

  1. Attractive appearance – the lines of the water supply are hidden from the eyes and do not spoil the beauty of the rooms in which they are laid.
  2. Saving the useful area of housing – pipes are laid in the walls and do not take away such valuable square meters from you.
  3. It is possible to arrange furniture and other objects with a closed installation of a water supply without any fears.

Polypropylene water supply pipes

Yet, there are a number of challenges and issues related to the closed installation of the polypropylene water supply.

  1. The need to perform strokes – the work is complex, laborious and not the most pleasant.
  2. It is allowed to install only those pipes that have a small coefficient of linear heat expansion in channels.
  3. Not all walls are suitable for trinification – some are too thin and fragile, as a result of this, to perform such work with them is undesirable.
  4. The number of fittings and various compounds with a closed installation of the water supply should be minimal – for the repair you will need to remove the external wall decoration.
  5. Carry out a preventive inspection of the water supply mounted in a closed way is almost impossible.

Only if you are prepared for a lot of labor and are certain that the pipes won’t flow should you select an installation plan similar to this one. If not, it makes sense to prioritize open installation, in which all connections are placed above the finish. Although this scheme may not appear as elegant, it is more dependable because any issues or leaks can be fixed quickly and with little effort. Furthermore, an exposed water supply can easily be updated by adding new lines or by simply replacing the existing ones.

Installing the pipeline in an open manner

Fascinating! The polypropylene water pipeline is installed in drywall imitations as an intermediary circuit between an open and closed installation.

Features of the installation of pipe from polypropylene

The purchase of a special tool and a set of components—fittings that guarantee complete installation—usually goes hand in hand with the installation of a watering system based on polypropylene pipes. A polypropylene pipe soldering iron is a specialized tool that can be rented or purchased.

You will need a cutter by pipes (special scissors) from a set of required tools. On the other hand, using a hacksaw to cut polypropylene sleeves is totally acceptable. You will need a construction roulette and a marker (pencil) or similar tool for measurements. In the installation case, the corner ruler or transportation won’t be unnecessary. Worships or a divorce key are also required for a full set.

An essential instrument required for installing polypropylene pipes. With polypropylene pipeline, cutting is possible both quickly and precisely. However, a standard hacksaw for metal can be used in place of this instrument.

Plumbing technology does not require any special technological actions for the assembly of polypropylene pipes. However, what level of prior experience with polypropylene rations is still required? The total lack of expertise raises the possibility of unpleasant future effects from the way the water supply is operated. Additionally, the work is roughly organized as follows:

  1. The pipe of the water supply line is cut down in size.
  2. The place of cut (and compounds) is cleaned from burrs.
  3. The desired fitting element is selected and adjusted.
  4. Polypropylene soldering iron is equipped with appropriate nozzles.
  5. Turn on the heating at the soldering station (heating limit 260ºС).
  6. The joined elements (fitting and the end of the pipe) are made into contact with the nozzles.
  7. They heat them for several seconds (4-10), depending on the thickness of the wall.
  8. Remove from nozzles and manually quickly connect, inserting the end of the pipe into the body of the fitting until it stops.

The latest action is unique in that it needs to be completed swiftly and precisely, with the pipe and fitting fixed in place. Waiting for a minimum of thirty seconds is recommended after connecting the elements. Enough time has passed for the heated regions and their close connections to solidify.

When plumbing devices’ lines to the main water source break, the installation of any kind of water supply using polypropylene pipes is regarded as competently done. Plumbing installation ought to be done simply, parallel to the building’s walls or floor. It is advised to install the CVS line above the GVS line if the two highways are in close proximity to one another.

Polypropylene pipes are significantly less rigid than metal pipes.

As a result, careful consideration should be given to the sturdy fastening of pipelines to the base when installing polypropylene. There must be fasten support brackets every 1.5–2 meters along the pipeline line.

Building a water supply line with minimal loads on pipelines is a good idea. It is not advised to bend a polypropylene pipe’s body; doing so will cause the fold to become an obstruction. Special fittings, such as bypass or angular ones, should be used to address these issues.

The order of work

The reason for the work and the location of the pipeline installation directly influence the work procedure. Naturally, the layout will differ for a bathroom, kitchen, country, or country home, but there are a few standard methods that can be identified so that the water supply can be mounted for any purpose.

It is convenient to illustrate these subtleties with an example of a bathroom installation, t.To. This is the most typical situation.

The diagram below is an example of a typical one. The toilet is the first point of water cleansing, followed by the sink, the bath, and the water heater, if you are looking at the picture from left to right. On the right is the feeding line, which consists of hot and cold water risers.

Standard circuit for a battery-powered water supply, Rice.7.

The risers are where the water supply assembly begins. Installing counters is what they do first. To accomplish this, a shut-off tap installed on the riser removal must first have a filter-gryazevik (a mechanical filter for rough cleaning) mounted on it before the water meter can be installed. Moreover, pipe PP will be used to construct the entire system. A non-detachable threaded connection is used to establish a connection with the counter.

Installing meters on polypropylene pipes is Rice 8.

Additionally, the pipes’ locations are marked on the wall, and clip holders are positioned roughly every 50 to 100 centimeters.

It is crucial to watch out that they don’t fall into the pipe or fitting connections when they are attached. Particular jumpers are fitted at the pipe intersections.

Threaded connections are installed at the consumer points.

Rice.9. Cross to allow pipelines to cross.

Wrestling for heating

Prior to installing the polypropylene-based heating system, meticulous planning must be done on paper, just like with the water supply.

The distinctions lie in the intricacy of the computations, which are best left to experts in thermal equipment.

The type of heating system determines which type is used. It is quite possible to get away with using a PN20 brand for this arrangement if the system operates at low temperatures (up to 65C). With reinforcement, high-temperature schemes (up to 95C) are employed.

Video: Master’s instructions for installation and rations:

Usually, 20 mm of coolant is sufficient to supply radiators. It is possible to install a wider pipeline, but doing so will significantly raise the project’s cost. Situations where the length exceeds 30 meters are the exception. Here, a precise 32 mm diameter is required.


Fittings are used to join polypropylene pipes together into a single system.

They serve to seal the compounds, organize the branches and bouncers, and create transitions to pipes made of different materials or with varying diameters.

Transitions—bags, plugs, crosses, tees, couplings, traffic jams, bounces, corners, and caps—are among the different fitting types.

The distribution of the flow in multiple directions is the aim of the bounces and crosses. You can change direction at corners. Pipes with the same diameter can be connected using couplings, and pipes with different diameters can be connected using pipe transitions. To connect to pipelines of a different kind, a range of fittings and adapters are utilized.

The materials used in manufacturing and the installation techniques themselves are characteristics of fittings for polypropylene pipes. Given that polypropylene can only be mounted once, every fitting is set.

Installation instructions

The bell-shaped welding, also known as a coupling, is the primary technique for joining components into a single system. It means to connect the fittings through an extra coupling rather than to join them. This is where the welding is supposed to happen after the connection.

The following will also be required for the installation:

– specialized welding equipment;

– pipeline, using unique nippers.

The initial installation step involves getting the material ready. A pipe cutter is used to cut the pipes short in accordance with the planned layout.

After that, a chamfer is removed from the end using a gas reminator. There is a unique standard DVS-2207-1 for the chamfer, and it stipulates that the chamfer must be 15 degrees and 2-3 mm deep.

Next, the welding area needs to be completely degreased and cleaned of all pollutants. The couplings can be heated simultaneously from the inside and the outside using a welding device. Furthermore, this only occurs to a certain depth. Since homemade devices cannot provide uniform heating of the required areas of the material, their use is not advised for these purposes.

The fitting is placed on the welding pin once the device has heated up, and the pipe is then put into the sleeve. The diameter and material will determine how long it takes to heat, but usually a few seconds will do. After that, they are taken out and cautiously put back into one another.

However, it is not acceptable to rotate in a way that could destroy the compound that has already started to take hold.

You can now go straight to welding. The temperature setting for the welding machine needs to be 260 s. This level of heating is adequate for swimming polypropylene and won’t harm the heater’s Teflon nozzles.

It is required to hold them in this position for a few seconds after the pipe is inserted into the fitting to the stop. This is actually where the welding work ends.

The junction will cool down and become operational in a minute.

The simplest method of installation is in different pipeline sections. These sections are fused together to form a single whole once they are all prepared. Special clamps are used, fastened to the walls or the floor, so that the completed pipeline does not hang in midair.

As demonstrated by experience, polypropylene pipes are currently the most practical, straightforward, and long-lasting option for setting up the heating and water supply systems. The pipeline can operate in the serviced mode for several decades provided it is installed correctly and has a well-planned wiring pattern in the bathroom.

How to make a welding machine yourself

Since a high-quality welding apparatus is not inexpensive, it is preferable to either rent one or create one yourself.

In case the second option is selected, you must get ready beforehand:

  • electric drill;
  • nozzle (sleeve) of the required diameter;
  • an iron -out iron iron;
  • puck and bolt for him;
  • Thermal paste for computers.

The following will be the order of events:

  1. To increase the degree of heat transfer, the sole of the old iron is treated with paste, after which you need to fix the Teflon sleeve. Its position is determined in advance – they have a wide part to the bottom or to the top.
  2. They cut a nose at the iron so that it is more convenient to work with it in the immediate vicinity of the walls.
  3. Heated an ironing device until it turns off again.
  4. The presence of an iron of a thermal attemptor allows us to more accurately determine what temperature the unit has been heated. There is a simpler method to find out the degree of heating of the device using lead. The fact is that this metal begins to melt at 230 degrees, which almost coincides with the temperature required to perform welding.

The ration-related actions that follow are comparable to the assembly described above.

Installation of sequential wiring

Tees are used to implement the principle of the exit sequence on the incoming pipe. On a supplying pipe, they are installed one after the other, each in front of a separate supply object.

By doing this, you can join two or three objects. It is more advantageous to dilute in parallel.

Installation of parallel wiring

A specific detail—the collector—is required in order to install parallel wiring. Collectors made of polypropylene are designed to install hot and cold water supplies for three or more outputs.

A node with multiple outputs, the collector is mounted on an incoming pipe. Typically, every output has its own valve, allowing you to isolate and insulate each branch’s water supply.

The wiring is frequently combined. For instance, a private home’s cold water supply is installed in parallel following five output collectors. Exits are located near the shower, boiler, washing machine, sink, and toilet.

Only the hot water needed for a sink and shower needs to be diluted from the boiler. It’s where the tee is installed. The boiler feed is received through one input hole, and both objects are divided by two exits.

Note: In the example above, as soon as the water in the sink is turned on, the hot water supply (which also refers to the water temperature) in the shower cabin will drop, and vice versa.

PVC pipe welding technology of polypropylene

Following certain guidelines is necessary when handling polypropylene pipes. A correctly installed connection can tolerate high pressure and is sealed.

Welding at negative temperatures

At low temperatures, high-quality welding is challenging to achieve. Welding polypropylene pipes at air temperatures below +5 degrees is not advised. The plastic becomes brittle and the spike may leak at temperatures below freezing. This will cause the pipeline to burst or leak. The location where welding is done stays warm during the winter by setting up a tent and using a heat gun.

Is it possible to cook products of different manufacturers?

Plastic pipe manufacturers stress that soldering polypropylene products of different brands is not recommended. There are several ways in which pipes and fittings from different manufacturers can vary:

  • admission to diameters;
  • softening speed;
  • color shades.

When different technical characteristics are attempted to be combined, it causes problems during installation and ultimately leads to the collapse of the entire structure.

Assing welding of large -diameter products

When constructing highways, joints are made in the joints when welding large-diameter plastic pipes (starting at 63 mm). The foundation of this technique is heating and melting the pipe ends, then connecting them with enough force.

Ensuring that the workpieces’ ends are perfectly even is crucial. This enables the adhesion to reach its maximum strength while remaining unable to function under high pressure.

Fitting tributar

Polypropylene pipes up to 40 cm in diameter are boiled using a specialized manual instrument. consists of nozzles for fixing blanks and a centering device. Using a file or grinding paper, clean the pipe’s ends after the cut. The future pipeline’s specifications are soldered and pressed into the heated device. All motions occur swiftly and clearly as the material warms up to the appropriate temperature.

Please be aware that the outer diameter of the pipe should be greater when dealing with a bell-shaped or coupling adult. After welding, stay still and avoid moving or rotating the components for the duration of the cooling period to prevent deformation.

After welding, stay still and avoid moving or rotating the components for the duration of the cooling period to prevent deformation.

How to cook reinforced pipes (plus video instruction)

Heating systems, hot water supplies, and "warm floor" installations all use reinforced pipes. Prior to beginning work involving reinforced polypropylene pipes, it is ready; Shaver cleans the aluminum layer. This is required to ensure that the design does not leak and that the aluminum foil does not degrade when it comes into contact with water during operation.

Fittings come in sizes that allow for the inclusion of pipes without upper layers.

Installation of water supply from polypropylene pipes

After removing the outdated pipes, you can begin installing the new items. Check the water supply circuit that was previously drawn first. Examine it in comparison to the system you just disassembled. Make any necessary adjustments to the plan. The plan then needs to be moved to the walls; use a marker to mark the locations of the pipe installations. Additionally, indicate where the locking reinforcement and tees are located.

Water pipeline fittings and markings made of polypropylene

Crucial! Select locations for tees, knees, and other fittings so that you can readily arrange a ratio of polypropylene pipes inside of them during installation.

The following work needs to be done.

Step 1: Install filters on the CVS and DIS lines if at all possible. The tap water quality is far from ideal, and the use of these products will only improve and lengthen the lifespan of your polypropylene pipes and plumbing.

Step 2: Install counters for hot and cold water. It is ideal for this work to be done by a specialist with the necessary authorization and tolerances. You will need to invite someone from the management company or HOA for the counters to accept acceptance and sealing after installation.

Water meter installation

Step 3: Install the collector by manually parallel wiring the polypropylene water pipeline.

Step 4: Attach the clips that will hold the polypropylene pipes in place. If a closed installation is intended, start by using a perforator to make a final hole in the walls.

Step 5: Assemble the main CVS and DIS lines using soldering along with tees and additional fittings and components. In the section that follows, you can learn how to connect polypropylene products.

The installation of the water supply

Counseling! Consider both the length of the line and the portion of the product that will be soldered into the fitting when cutting the pipe for a particular section of the water supply. Each of them requires approximately 15 mm of polypropylene pipe.

Step 6: Install supply pipes and locking reinforcement for each cold and hot water user after that.

Supply pipe installation and reinforcement

Step 7: Attach the polypropylene water supply to one of the shells and verify that the system is operational as a whole.

Step 8: Remove any issues that were found during the audit. Next, link the plumbing and all required equipment to the water supply.

Step 9: Make use of the waste that was created during construction cleanup.

Step 10: If preferred, use drywall or ornamental plastic boxes to seal the water supply line.

Contact welding ration

Pipes and fittings should be connected as dependable as possible because the water supply operates at a relatively high pressure.

1. Using a grinder, pipeline, or specialized scissors, pipes are cut into the required length segments. Products that have aluminum reinforcement must be cleaned using a unique tool called a Shaver.

Pipe cleaning tool with reinforcement shavers

2. It must be removed from their edges chamfer at a slight angle in order for the segments to be freely included in fittings. In this instance, the recess’s size should not exceed 3 mm. It is used FACKOSARER for these purposes.

3. Alcohol or a white spire is degreased from the pipes’ ends.

4. They are applied to the mark, which is equivalent to the fitting’s depth less a few millimeters (for a pipe measuring 25 mm, this equals 16 mm);

5. Pipe and fittings are positioned on either side of the soldering iron nozzle so that they heat up to the necessary temperature. The nozzle’s ends feature a tiny cone that fits on them with just a little effort when wearing a pipe.

Attachment to the nozzle

Device for welding (soldering iron)

6. The soldering iron’s temperature regulator needs to be set to 260 °C if one is present.

7. Interval between pipe heating According to its thickness. The pipes and fittings are easily removed from the nozzle (dorn) and coasted after withstanding the necessary amount of time, which is specified in the soldering iron instructions and can range from five to fifteen seconds. Since polypropylene solidifies in just 30 seconds, it is best to complete this task in a single motion with small displacements as soon as you can.

Crucial! It is not advised to rotate the pipe and fitting during the warming up process to protect the plastic. Avoid forcing it to cool.

8. Because connecting large diameter products is more challenging, a specialized device is used to connect them.

Suggestions. It is best to practice a little to get comfortable with welding. Purchase a few fittings and attempt to fix them on small segments.

9. Using a regular knife, small streams created during welding are eliminated.

10. The water supply is assembled, filled with water, and then checked for tightness under pressure. It is chosen here 1.5 times higher than the nominal value. You can use a car pump to raise the pressure. Problem joints can be removed if required, and new segments can be soldered into the system.

Crucial! There is a 2-hour window after the soldering is finished for the system test.

Restrictions on use

Polypropylene welding table for pipelines.

Even with all of their advantages, polypropylene pipes have drawbacks that should be considered when organizing heating systems. This also holds true for the properties and selection of polymer raw materials. Standards state that pipes can be made from a variety of brands of polypropylene; the brand is listed on the outside walls of the product. The product’s intended temperature and pressure are what determine its nominal strength. This is the general rule: the operating temperature decreases with increasing pressure and vice versa.

A unique gradation of polypropylene types and application areas was introduced in order to compare the properties of polypropylene pipes. This is how she appears:

  1. PN 10 – thin -walled pipes for cold water supply and warm floor (operating temperature up to 45 ° C, working pressure 1 MPa.
  2. PN 16 – for cold water supply with high pressure and eyeliner eyeliner with reduced pressure.
  3. PN 20 – for pipelines of hot and cold water supply (operating temperature up to +80 ° C, pressure 2 MPa.
  4. PN 25 – for central heating and hot water supply (up to +95 ° C), working pressure 2.5 MPa, three -layer pipes reinforced with aluminum foil.

Diagram for installing polypropylene pipes featuring upper wiring circulation.

The product on the market is a PN 25 fiberglass-reinforced pipe. It’s not like the usual in that the joints don’t need to be cleaned. Everybody wants to cut costs wherever possible, and installing polypropylene pipes is no exception. This can result in major future costs when setting up the water and heating supply systems. The price variation based on brand can be substantial. However, if hot liquid is allowed to leak into a pipe meant for low operating temperatures, it may burst. You must keep in mind the unique characteristics of polypropylene pipes before organizing their installation.

Due to its high coefficient of linear expansion, polypropylene stretches and expands in diameter when exposed to high temperatures.

Diagram of a polypropylene pipeline equipped with temperature sensors.

The effect is invisible if the pipeline is intended for a cold liquid. even at temperatures as high as 45 °C. On the other hand, the pipe may fracture or harm the external cladding in situations where there is a lack of room for expansion. When installing pipelines on the street, keep in mind that pipes may contract during the winter, causing tears and harm to the fittings.

The implementation of compensation loops is the only dependable way to avoid such outcomes. Their frequency and size are specified in the specifications, so you can make them by hand, leaving the untouched P-pipe sections. Numerous businesses sell completed shaped products as loops. A few remarks are necessary regarding the polypropylene installation techniques. Any of the aforementioned installation techniques—hidden pipeline laying, open gasket, laying in boxes, mines, or soil—can be used to install such products. High-temperature water pipelines should be installed with the potential for later longitudinal displacement.

Fittings PP of water systems

Fitting is a term borrowed from English. Literally translated, this is "mount, attach, do assembly." Specifically, the polypropylene pipeline has a structurally fitting component.

This element can be shaped like a cross, tee, 90o or 120o corner, etc. To connect the locking and additional reinforcement, there are fittings with threaded inserts. You can carefully avoid the areas where one pipe meets another thanks to special bypass components.

A vast array of fittings is produced in conjunction with polypropylene pipes. Fittings, or installation elements, greatly increase installation freedom by letting you select the best technology for building water supply systems.

It is easy to construct water supply wiring schemes in practically any configuration by using any of these mounting elements. A coupling is used to connect two polypropylene pipes in a straight line from one to the other. If a change in pipe diameter is required within the straight area, the same fitting is utilized to make the transition. Using corner fittings makes connecting pipes with a turn simple.

Different kinds of adapters are made to be used with polypropylene pipes when installing water pipelines. The other type of such elements is used for mechanical threaded connections if one type is intended for use. By eliminating the need for soldering technology, fittings for a mechanical threaded connection enable the power squeezing method to create an entirely strong and dependable connection.

Apart from the conventional techniques of attaching, such as using polypropylene ratios and mechanical connections, the technology of adhering scheme components is employed. The benefits of this technology include the ability to obtain a qualitative appearance for the water system because there are no deformations at all.

Apart from the threaded connecting technique, water pipeline parts are frequently joined using this technology. For example, you can easily construct a distribution collector for the CVS with your hands using special glue, tees, and polypropylene pipes.

In this instance, the master technology’s actions consist of the following steps:

  1. The pipe is cut in size and cleaned from burrs.
  2. The surface of the pipe at the junction is degraded.
  3. A layer of glue is evenly applied to the surface.
  4. The end part of the pipe is inserted into the fitting until it stops.

The glue will dry in 20 to 25 minutes.

Advantages and disadvantages

Among the primary benefits, the following stand out:

  • resistance to corrosion (metal systems are quickly rusted, while it does not threaten plastic at all);
  • cheapness (they are cheaper than pipes from other materials);
  • lightness (they weigh very little, which also undoubtedly prolongs their life, because the harder the system, the greater the load both on it directly and to the rations, fasteners to the wall, etc.D.);
  • Polypropylene pipes are easy to mount (of course, we could not once again mention this advantage, just follow the installation of SNiP);
  • Such systems are easy to clean;
  • strength (plastic can be strong; in addition, these pipes can be additionally strengthened using compensators and special “knees”).

The installation requirement for a special tool is the only one of the drawbacks.

The installation instructions for polypropylene pipes are provided in the video below.

Additionally, installing water supply systems requires guidance and knowledge of SNiP, just like any other redevelopment.

How to use a welding machine for polypropylene

The basic components of a polypropylene welding machine are a handle, a thermoregulator, and a heating slab. With their Teflon coating, attachment to both sides of the heating plate, and various diameters, the nozzles can theoretically solve any household issue.

  • First, the required length of the pipe is measured and with special scissors it is cut strictly on the mark. With the help of the endings, we remove the burrs, in the presence of an external reinforcing aluminum layer, it is also removed. The cut place is cleaned and degreased. The nozzles selected in size are also degraded.
  • To determine the depth of the pipe entering the fitting, they must be connected unbearable and put the mark with a marker. The nozzles are installed on both sides of the welding machine, one of them puts the end of the pipe, and fitting on the other.
  • The device turns on and the heating of the nozzles begins. As soon as the bulbs on the thermostat went out, then the products are warmed up to 260 °. After that, a pipe and fitting are installed on the device and the required time is withstanded, which depends on the diameter of the pipe. Pipe and fitting are connected to the mark. Your movements are operational and accurate! And no rotation! After a few seconds, the monolithic part is ready.

Polypropylene pipe installation utilizing welding

In order to install polypropylene pipes effectively on your own, you will require a minimal level of proficiency using a welding machine. This can be found out at pipes that needless trimming.

Here are some pointers for setting up a polypropylene water supply:

  • It is recommended that the device of the water supply in the apartment from polypropylene be carried out from the consumption points to the input of the distribution devices.
  • The elements of fasteners are installed along the entire planned line, pipelines are fixed on them, thereby united in a single system.
  • If the laying of the water pipeline from polypropylene pipes provides that the pipelines of hot and cold water are located nearby, then the cold water line should be laid higher, which will eliminate the loss of condensate on it.
  • The pipes are located strictly horizontally or verticals and are fixed only at right angles.
  • In hard -to -reach places, the pipes are mounted in a separate stage.

Fundamental conditions for high -quality installation

For the purpose of installing polypropylene pipe in a high-quality manner, there are requirements. The nuances that you should be aware of start as soon as you plan the work, buy the supplies and fixtures, and get the tool ready.

How do weather conditions affect

When installing polypropylene pipelines that require welding, the air temperature should be at least +10 °C. Sewer pipes that are joined to the bell without the need for welding are an exception.

The subtlety is that the connected parts cool more quickly when the air temperature is too low; this process takes only 30 seconds, of which 4 seconds are allotted for a minor adjustment to the guide compound. Low air temperature can result in a poor-quality connection because it does not allow for correction time.

Please take note: Do not install polypropylene pipe at negative ambient temperature values!

The effect of meteorological conditions

  • Direct sunlight accelerate the heating of polypropylene parts, since the starting temperature is higher than the calculated;
  • The wind accelerates cooling, reduces correction time (it is recommended to set the shield);
  • Rain requires mandatory protection of the place of work, since it is prohibited to weld wet parts.

Take note! Adhering to the necessary work conditions is crucial. A leaky compound results from the use of polypropylene welding technology improperly.

Replacing the node is the only way to correct the error.

The choice of components

The following guidelines will assist in preventing mistakes when installing polypropylene pipelines:

  1. The choice of pipes and fittings is carried out depending on the purpose of communications.
  2. It is better to buy material from one manufacturer – in this case, pipes are ideal for fittings. Focus on marking. The color of the goods on the quality and technical characteristics of the products does not affect, but is rather a “business card” of the manufacturer. For example, gray pipes produced by the Czech Republic, white – Turkish or Valte. The exception is black products – they are resistant to ultraviolet radiation.
  3. If it is planned to hide the pipeline to the floor or walls, then it is better to choose green material – it is the production of Germany and is rightfully considered the highest quality.
  4. The material should be purchased according to the detailed plan-scheme of the future pipeline.

Take note: Fittings can be purchased precisely as planned. One to 1.5 meters of pipe should be purchased with some margin.

What does the labeling of polypropylene materials mean

Manufacturers provide a range of pipe diameters with varying wall thicknesses and functionalities. When selecting installation materials, keep the following in mind:

  1. Installation of cold water supply PN10, PN16 (used infrequently).
  2. Installation of hot water supply PN20 or PN25 (25 more expensive, which is not always justified in a private house, unless the owners use boiling water).
  3. Installation of water heating PN25.

Be aware that materials made of polypropylene cannot be used to install steam heating. They distort because they cannot tolerate the hot steam’s temperature.

Work technology

The ability to install and use plastic communications with your hands just thirty minutes after work is the primary benefit of using them for behavior and water allocation. The following techniques are available for installing polypropylene pipes:

A concealed water supply is typically located in an apartment where the pipes are embedded in the wall. Although this is a more practical option, it is more challenging to execute without a master’s assistance. especially because demolishing the wall is necessary. As such, external pipeline installation is the more common method.

Picture of exposed pipes

Also, the water supply and heating systems affect the installation circuit. One, two, or three pipes can be used.

Here are some instructions for installing a single-pipe heating system made of polypropylene pipes:

  1. First, the system is designed. In a single -pipe circuit, a heating apparatus (say, boiler), radiators, pipeline, water tank and additional installation elements are used; Photo is an example of a scheme
  2. Next, the boiler is connected. You need to install the thermostat and other devices to protect the water supply on the main pipe. Keep in mind that at the lowest point of risers you will need to install a water drain. This will be needed during the repair or, if necessary, reload water;
  3. On the supply pipelines you need to install a pump and a filter that will carry heated water from the coolant to a single -pipe heating system;
  4. When the system of drainage of warm water is ready, polypropylene pipes must be interconnected. They are centered in the clamps that will help to ensure maximum evenness of the cut. After that with scissors, communication is cut to the desired size. The cut place is cleaned with degreasing compounds and wiped with sandpaper to obtain a perfectly flat surface. SNiP rules for the installation of polypropylene pipes say that you must make a chamfer. It is performed in a size of 2 mm at an angle of 45 degrees with a special machine or a captainer; Photo – pruning
  5. After preparing fittings and heating tools, which will be installed by the installation of polypropylene pipes. Soldering iron or clutch are included in the network and heats up to a certain temperature. At this time, a suitable nozzle is inserted into the pipe. The diameter can differ by 1 mm, but no more. Clamps the nozzle is tightened on the pipe and heats up with a soldering iron. After a certain time (this indicator determines the diameter of the pipe and wall thickness) the inverter is turned off, the second segment of the pipe is installed in the nozzle. The sequence of actions does not change, while considering that it may take more time to connect for rotary elements; Photo – soldering
  6. After heating, you need to carefully remove the pipes from the fitting, but you cannot scroll and squeeze them – you can break the tightness of the connection and then you will have to cut polypropylene again;
  7. The entire system from the radiator to the coolant is installed on supporting brackets, but at the well and walls you need to leave the pipes as if by weight. The average distance of the brackets is 20 centimeters. This will help protect the system from overload during operation.

The connection of a boiler or boiler and pipes may follow different principles depending on the scheme chosen, but the connection of polypropylene segments is almost always done in accordance with one principle.

Characteristics of polypropylene work:

  1. The angle of inclination is selected according to the requirements of SNiP and Yenir. This is a very important point without which the water supply is not effective;
  2. It is necessary to adhere to the temperature of the melting of polypropylene and not overexpose the compounds by time; Photo – welding time
  3. Literally a few minutes are required to cool the plastic, but for this period it is necessary to ensure complete immobility of communication.

How to Install Polypropylene Pipes in a Video

Where to begin

You must be well-prepared if you want to complete the task quickly. In order to accomplish this, you must resolve the following issues:

  • At the first stage, the instructions for the installation of polypropylene pipes should be carefully studied.
  • Then you need to make calculations, draw up diagrams and purchase materials for assembling the pipeline.
  • Next, you should acquire skills to carry out pipe connection. As a rule, it is enough to perform two or three trial joints, in order to then the pipe assembly without problems.

Study of theory

Prior to beginning work, it is advisable to familiarize yourself with the characteristics of polypropylene pipes and research the problem of compound execution. Regulatory materials, or SNiP, contain a wealth of important information.

Drawing up a scheme and procurement

The prior wiring should serve as the foundation of the plan if the pipeline is installed in exchange for the old. To design a plan for installation in a new building, it is preferable to work with experts.

It is important to keep in mind that installation cannot begin until a comprehensive project containing intricate wiring schemes has been assembled, taking into consideration all of SNi’s requirements. The moment of purchases follows. Pipes in the required quantity, along with fittings for the connections, must be purchased.

There are several varieties of polypropylene pipes available, so you must consider the future pipeline’s operating conditions when making your selection. For instance, some pipes are made exclusively for indoor use.

Since the pipes cannot support the weight, using this material for external networks is prohibited. Furthermore, we can infer conclusions about the conditions of use for which a particular type of pipe is intended by examining the labels on pipes. Thus, in line with SNiP:

  • PN 10 pipes are allowed to use only for cold water.
  • Material with pn 16 labeling can be used to install both varieties of household water supply.
  • Pipes indicated by the PN 20 symbol can be used both to install hot water supply pipeline, and for wiring in the heating system.
  • PN 25 pipes are used mainly for heating systems.

Counseling! Labeling pipes with PN -20 and PN 25 have extra reinforcement in the form of metal foil or a layer of fiberglass. It is possible to shield pipes from temperature deformation with this kind of reinforcement.

Fittings, or connecting parts, will also need to be purchased in order to complete the installation. The ensuing components might be necessary:

  • Clushes. These are connecting parts that are used to connect direct segments of the pipeline. In some cases, a special coupling may be required to switch to a threaded connection.
  • Corners. These are details created to perform rotation. As a rule, corners with an angle of 45 degrees are used.

  • Tees or crosses. These fittings are used to join the main branch of the pipeline of additional.
  • Adapters. Such fittings are necessary when the connection of pipes of different diameters is performed.
  • Clamps. The use of clamps is necessary to attach the pipeline to the walls. If the pipeline is not fixed, it can sag over time.

Counseling! The wiring scheme dictates the type and quantity of fittings.

Necessary tools

To install polypropylene pipes, you will also need to buy a tool in addition to the materials. Essential:

  • Electric welding apparatus equipped with Teflon nozzles of the desired sizes to perform pipes.
  • Special scissors with wedge -shaped incisors – pipelines.
  • Calibrator – special scanning to prepare the end of the pipe and remove the internal chamfer.

Areas of use

This material can be used in a wide range of systems, depending on the diameter, design elements, and varieties of polypropylene. These are, first and foremost, water supplies.

Water is typically delivered to consumption points via 20 mm diameter tubes. 32 mm must be used for plots with larger bandwidth (collectors, risers).

However, the type is also influenced by the water’s temperature when it is supplied. For instance, pipes with an aluminum film layer of reinforcement are used for hot water supplies.

The design of heating systems includes an aluminum or fiberglass reinforcing layer. Furthermore, stitched polypropylene pipelines are typically installed in regions where water temperatures are higher than 75C. When compared to their whole analogs, they have a lower coefficient of thermal expansion. By doing this, distortion from high heat is prevented.

Another industry that makes extensive use of polypropylene pipelines is sewerage. Because of this material’s characteristics, sewer systems that are resistant to leaks and blockages can be designed. For these uses, 110 mm pipes are most frequently utilized; however, 50 mm options work well for sewage in the kitchen or bathroom.

Furthermore, the SNiP regulation does not currently advise against the use of different kinds of water pipelines in residential buildings. The only material that can offer the required degree of dependability and hygienic purity is polypropylene.

Distinctive features of polypropylene pipes

It is quite possible to create a complex system out of a challenging polypropylene pipe water supply system. However, it is best to learn as much as possible about the topic of installing a water supply system based on PP pipes beforehand.

Polypropylene pipes are the primary component of the mounting process, so keep in mind that the following products are available for purchase:

  • single -layer on pressure up to 10 ati (PN10);
  • single -layer on pressure up to 16 ATI (PN20);
  • Three -layer on pressure up to 25 ati (PN25).

Installing the home sector’s cold water supply line and building water-warming floors are excellent uses for the first kind of polypropylene sleeves, which have a working pressure of up to 10 atmospheres. A cold water supply system with a working pressure of up to 10 atmospheres is typically mounted from such material.

A different pressure value is used in the production of polypropylene pipes used in water pipeline installations. Usually, the pipe’s body has a marking that indicates the maximum pressure value. Use color markings to indicate the type of water supply (DIA/HVS).

The HVS highways are also wired using the second type of product, which is intended for operating pressures up to 16 ATI. If the system’s maximum temperature does not surpass +60°C, they can also be utilized for the hot water line device.

The third modification, PN20, is characterized by more robust products that can be installed for heating contours in addition to cold and hot water supply systems. Such polypropylene can be used in systems where the coolant temperature is above 80º and there is a high working pressure (up to 20 ATI).

When constructing private housing, the CVS water supply is typically installed using PN16 polypropylene pipes. The installation of DHW highways can use the same pipes as long as the temperature compliance

Although hydraulic water supply is one application for propylene pipe designated with the acronym PN25, it is primarily intended for use in heating systems. produced utilizing the same three-layer technology. Aluminum foil is only used for the reinforcing layer. + 95ºΡ is the operating temperature limit value.

Products sold under the PN25 brand are positioned as examples of innovative development that made it possible to eliminate thermal expansion, a major problem with polypropylene sleeves. These products are actually universal and can be used with any kind of water supply device.

It is important to consider the unique installation of these pipes since the reinforced layer is removed during soldering. A soldering iron is only used to heat a polypropylene base.

The polypropylene sleeve’s structure was created with DHW and heating systems in mind. When utilized as a reinforcing layer, aluminum foil serves as an insulator just as effectively.

Most polypropylene water supply pipes currently on the market are labeled with a specific purpose in mind. Usually, markings are made by painting colored stripes straight onto the pipe’s exterior wall:

  • Blue (green) under HVS,
  • Red (brown) under the hot water or heating,
  • orange for any water supply system.

The selection of pipes is facilitated by color marking.

Consistent and parallel wiring of a water supply from polypropylene

The owner of the apartment or private home must determine how the hot and cold water supply pipes from the heating boiler or riser will be diluted when creating the preliminary circuit of the polypropylene water supply. There are two approaches, consistent and parallel, just like in the prior instance.

Information that may be of interest to you is: The ball is a brass ball.

Simplicity and material economy are the hallmarks of consistent wiring, also referred to as trigeminal wiring. It is set up as follows: a line is laid from the source of water to the very last user. The entire length is shattered by thirds. Water users are connected to the CVS and DHW common pipes through them. However, one major drawback is concealed behind the consistent scheme’s simplicity: when multiple devices operate simultaneously, the pressure will drop significantly. This may not be a big deal for small city apartments, but it can be a big deal for a large country cottage.

Cautious pipe wiring

Fascinating! It is occasionally mentioned that another disadvantage of the water supply’s sequential wiring is the requirement to totally block the DHW and CVS lines in order to repair or replace a specific device. However, the solution to this issue is very straightforward: the ball crane crashes between the common pipe branch and the water consumer. In this instance, it is not necessary to entirely shut off the water supply in order to perform repairs.

Parallel wiring of the water pipeline from polypropylene is more difficult – immediately after the riser or boiler, the collector is mounted, and separate lines of the CVS and DIS to each shell, soul and other consumers are already departing from it. All pipes going to them are equipped with valves overlapped for maintenance, repair or replacement of the device. Parallel wiring of the water supply prevents the pressure and temperature of the water on each individual consumer when the number of simultaneously included devices changes. But at the same time, such a scheme requires more pipes. In addition, it takes up a lot of space and, if possible, parallel wiring should be performed in a closed way.

Unusual use of propylene pipes

Acquire a variety of fittings and learn how to use a soldering iron to create a multitude of useful items out of plastic pipes.

Chairs can be made in a variety of ways. The 20–25 mm diameter p-pipe can be joined to create the legs. They can be strengthened by having a pipe welded around the outside from above or below. Subsequently, the back of the required value is soldered, and a chipboard sheet is screwed onto the legs. These can be covered with a foam-filled fabric beforehand.

Furniture made of polypropylene is ideal for gifting. Additionally, polypropylene pipe greenhouses are becoming increasingly common. This design is incredibly sturdy, and its light weight facilitates effortless assembly and disassembly.

A pipe can be dressed on a metal wedge that has been driven into the ground beforehand to create a small greenhouse. The pipe can then be bent and its second end can be dressed on another wedge. A film can be applied to such a design after multiple pipes have been bent, and brackets can be used to secure it.

To make the greenhouse more rigid, it is recommended that the pipe ends be concreted during construction and that some pipes be skipped. They can then be utilized to fasten tall plants.

You can use plastic pipes to construct a little gazebo. It is easy to locate the drawing on the internet, and it is sufficient to switch heavy metal for plastic. Nonetheless, it is still preferable to select large diameter pipes in this situation. For a roof, a lightweight, strong material like polycarbonate is appropriate. While not the most cost-effective choice, this one is easier to use and less expensive than a metal cook. The canopy is installed in a comparable manner.

The storage shelf system will work nicely in the pantry, children’s room, closet, etc. You can see a big load when it’s fastened to the wall, and creating such a design won’t be tough. Using the same idea, you can construct a rack with an infinite number of shelves by collecting small modules that can be cut from painted plywood or laminated chipboard.

System planning

PPR pipe does not bend, so when designing a wiring scheme, it is essential to have the fewest bypasses and turns possible. Ultimately, they are all completed with fittings and come at a reasonable price (in comparison to the pipe). As a result, we work to optimize the wiring by minimizing the number of bends, byputs, and turns.

Consistent (trigeminal) connection

Small systems use the installation of a polypropylene water pipeline with a sequential connection of consumers (home appliances and plumbing). They often have five or six points of connection. When the water supply is arranged in this way, one pipe leaves the riser and always goes around all connecting points. Since tees are also known as trigemakers, they are used in the construction of all branches in the PPR supply.

Installing a water pipeline made of polypropylene pipes and connecting customers in turn

A benefit of this system is that it requires fewer pipes, but a drawback is that each branch’s pressure decreases. Because of this, if there are only one or two operational points of analysis, the pressure might not be sufficient for the third point, which is farther away from the riser.

Parallel (collector) wiring

Another name for the parallel connection diagram is collector. This is due to the installation of a unique device called the collector following the riser’s discharge. This element has a fixed number of outputs and one entrance. There is made of metal and polypropylene. More affordable and appropriate polypropylene collectors for the water supply.

A distinct pipe connects each bastard to each consumer (or occasionally to a subset of consumers) according to the connection scheme.

A parallel schematic of the PPR pipes’ water supply

The benefit of this type of system is that all water parsing points have the same pressure; the drawback is the large number of pipes. Another benefit is that only one customer will be unemployed if a branch fails. The remainder of the system operates as it should. By the way, to turn off individual devices, you place taps (usually ball, but you can also put a valve if you need to adjust the pressure) at the collector’s output.

Entrance with plumbing and household appliances

Every way to install a polypropylene water supply pipe has a pipe that works for a specific customer. The flexible and hard eyeliner are the two methods of connecting to the system.

Strong eyeliner is more dependable because PPR fittings and pipes are very strong. Furthermore, there is only one thread in this instance, and that is at the consumer’s connection point. However, this kind of eyeliner demands extreme precision—a few millimeters can be the difference in error. They frequently use a flexible eyeliner because it is difficult to accomplish this when installing a polypropylene water pipeline with your hands. Use caution as some situations make it impossible to use it: connect gas speakers or boilers, supply water to storage water heaters, and use a hard eyeliner only when using heated towel rails.

Choices for applying a strong eyeliner

On the other hand, soft eyeliner doesn’t need to be applied precisely because a flexible hose made of stainless steel braid, or hose used to connect a washing machine or dishwasher, can level out mistakes. The space where plumbing connections are made or equipment is installed is adorned with tubes. It finishes with a metal adapter to which a flexible eyeliner hose is attached (its second end is connected to the device).

Adapters are connected to flexible hoses.

Because so much depends on the quality of the flexible eyeliner, this option is less dependable. The fact that there are two threaded joints and that this could be where a leak appears is also not the most pleasant moment.

Installing polypropylene pipes for the insulation and heating system in your house can be a satisfying project that saves money and gives you a sense of accomplishment for a job well done. You can successfully oversee the installation procedure and guarantee the durability and effectiveness of your system by adhering to these do-it-yourself instructions.

The most important thing is to make sure you are familiar with the equipment and supplies required for the task. This includes the proper size polypropylene pipes, fittings, insulation, and equipment like a heat gun, deburring tool, and pipe cutter. Having everything ready in advance will make things go more smoothly and cause fewer hiccups.

The secret to a successful installation is careful planning. Give your heating and insulation system a thorough layout, taking into account things like pipe routing, access points, and insulation placement. This will guarantee peak performance and assist in averting future problems.

Carefulness is essential when it comes to the actual installation of the polypropylene pipes. To ensure a tight and secure fit with the fittings, take care to measure and cut the pipes precisely. To avoid any sharp edges or obstructions that could obstruct flow or eventually cause damage, be sure to properly deburr the edges.

Remember to properly insulate the pipes after they are installed to reduce heat loss and increase energy efficiency. This is particularly crucial in regions with greater temperature fluctuations or in colder climates. You can dramatically lower your energy costs and raise the level of comfort in your house by making an investment in high-quality insulation materials and taking the time to install them correctly.

Lastly, don’t be afraid to ask for help when you need it. Although do-it-yourself projects can be very fulfilling, it’s crucial to know your limitations and seek professional assistance if you run into any difficulties or have any questions. It is always worthwhile to prioritize safety and high-quality workmanship in the long run, whether that means hiring a contractor to help with more complex aspects of the installation or seeking advice from a plumber.
