How and how to thread a water pipe correctly

It is essential to thread water pipes correctly if you want your home’s plumbing system to be dependable and leak-free. Knowing how to thread a water pipe correctly is crucial whether you’re replacing old pipes or installing new ones. This post will go over the steps involved in threading a water pipe and cover the equipment and methods required to do the task correctly.

It is essential to have a basic understanding of the types of pipes that are frequently used in residential plumbing before beginning the threading process. PVC, galvanized steel, and copper are some of the most widely used materials for water pipes. Each kind has advantages of its own and calls for particular threading methods. You also need to figure out what kind of thread and pipe size are right for your project.

Getting the tools and supplies needed for threading is the next step after choosing the right pipe material and size. The main tool used to create threads on the pipe is a pipe threader, which can be either manual or electric. Additionally, lubricant or cutting oil will be needed to minimize friction and promote smooth threading. For safety and accuracy, it is also imperative to have a pipe vise or clamp to secure the pipe during threading.

It is imperative to prepare the pipe end by cutting it squarely and smoothing out any burrs or uneven edges before threading the pipe. This stops leaks and guarantees a clean surface for threading. Once the pipe has been prepared, generously coat the area where the threads will form with cutting oil. Cutting oil contributes to the lubrication of the threading die and the pipe, extending tool life and guaranteeing accurate, clean threads.

It’s now possible to start threading the pipe after it has been firmly clamped in place and cutting oil applied. Place the threading die inside the pipe threader and line it up with the pipe end if you’re using a manual pipe threader. Once the threads are cut to the appropriate depth, gradually turn the threader handle in a clockwise direction while maintaining a constant pressure. To ensure correct setup and operation of electric pipe threaders, simply adhere to the manufacturer’s instructions.

Examine the threads closely after threading the pipe to make sure they are straight, consistent, and defect-free. Any flaws or unfinished threads have the potential to undermine the connection’s integrity and cause leaks. If any rough spots or irregularities need to be cleaned up, use a pipe reamer or threader. After you are happy with the thread quality, you can install the pipe into your plumbing system.

Step 1: Measure and Mark	Use a measuring tape to determine the length needed for the pipe and mark it with a pencil.
Step 2: Cut the Pipe	Use a pipe cutter to cut the pipe at the marked point. Make sure the cut is straight.
Step 3: Deburr the Edges	Use a deburring tool to remove any rough edges from the cut pipe.
Step 4: Clean the Ends	Wipe the ends of the pipe with a clean cloth to remove any dirt or debris.
Step 5: Apply Flux	Using a brush, apply flux to the outside of the pipe and the inside of the fitting.
Step 6: Assemble the Joint	Insert the pipe into the fitting and twist it slightly to spread the flux evenly. Make sure the pipe is fully inserted.
Step 7: Solder the Joint	Use a torch to heat the joint evenly, then apply solder around the seam. The solder will melt and flow into the joint, creating a watertight seal.

Master class. Threading of pipelines with a pipe tapping tool

Cutting the pipe should be the first step in the process (a bolgar can be used for this).

It is crucial that the cut be as smooth as possible since anything you try to screw onto such a thread won’t work. In other words, this needs to be handled beforehand.

You will have to educate yourself if you do not know how to operate a bolgar.

As we’ve already established, the threading process is not particularly difficult. All you have to do is get everything ready and adhere to the detailed directions provided below.

We reiterate that you must first cut the pipe uniformly. This is something we already know how to do, so let’s proceed to the next phase.

The chamfer must then be removed; otherwise, screwing anything—like the same fittings, for example—onto the resulting threads will be very challenging. Using a small bolgar, sharpen the pipe’s edge to about a 45-degree angle in order to chamfer it. It is not crucial that this angle be accurate, but the approach at the thread must have been truly qualitative.

Be mindful! It is important to mention the pipe’s condition briefly. In most cases, where the steel pipe is prone to rotting, new threads must be cut.

Check its wall thickness; if it’s too thin, it’s best to forgo threading in this particular area entirely. If you don’t, you will exacerbate the already fragile area and hasten its decay.

Let’s go back to the working process right now. Consequently, the metal needs to be lubricated in order for the tool to "go" on it more easily. Any type of lubricant—even lard and sunflower oil—will work for this. After that, attach the device to the pipe (a straightforward ratchet club is used in this instance), and then loosen the ratchet until it can rotate sufficiently freely counterclockwise. To "start the process," slightly press the tool. It won’t be necessary to press anything further because the work will proceed more quickly once it "bites" the steel in the future.

The actual threading process needs to be completed step-by-step. Essentially, proceed as follows: cut the first coil first, then turn the device in the opposite direction with the ratchet (this is required for the chip to form). You will also need to put in a lot of effort to cut the pipe if you ignore this advice. Cut the threads in this manner, little by little.

At this point, you’re undoubtedly going to ask yourself a reasonable question: how much cutting is really necessary? The answer is straightforward: the tool’s entire set of teeth needs to be on the pipe. Why? Nothing complicated here; the club is made to cut the metal to a precise depth with each turn. To achieve a high-quality and, if I may use this term, "finished" thread, every single tooth on the tool must be used in the process. Put simply, it is unlikely that you will be able to screw on the fitting correctly if you cut a 5-millimeter thread.

After cutting to the desired length, turn the ratchet to the "back" and disconnect the pipe. Subsequently, you can examine how to attach the newly threaded faucet, fitting, or perform any other necessary task. A comprehensive inspection is essential!

Kindly take note! As has probably been mentioned before, we advise holding the pipe with an adjustable wrench while threading it. The riser won’t break or turn in this manner. Additionally, avoid making the thread too low to the floor—you’ll never be able to do this!

Key varieties of the clubbing tool

The pipe club is initially split up into a few groups based on price and operational convenience, of course. Let’s become more intimately acquainted with these groups.

Group No1. Simple hand tools

Let’s not mince words: the most basic die in a straightforward holder is what we are discussing here. There is absolutely no difference in appearance. The circular guide frame has cutter clamps and two handles that are required for rotation.

Group No2. Hand tools with ratchets

This design is a little more intricate than the last one because the frame has a ratchet that allows the handles to be avoided being caught. All that has to be done is perform reciprocating movements with a single handle, much like when using a pump to pump water.

Vital details! Giving the first version of the club is preferable if you find both in the store and the second, even though their prices are the same. After all, using a ratchet in conjunction with low-quality metals used in cheap Chinese production is a very risky combination that you should absolutely avoid.

Group No3. Electric tools

However, in this instance, using the device only requires that the pipe be installed correctly and that the right button be pressed. An electric actuator can handle everything else flawlessly. Even though these tools only have a few hundred watts of power, they are able to develop a large force because of the gearbox’s significant gear ratio.

Tools used for this purpose

Make sure you have all the tools you’ll need on hand before you begin working.

Store-purchased kits contain pipe thread cutters. It can be a set of cluppers (this is the more practical option) or a die with the necessary diameter.

Prior to anything else, the pipe must be completely cleaned to remove any rust and leftover paint.

The threaded portion of the thread needs to be removed from the pipe’s end surface.

It’s critical to understand this! A high-quality tool should be used for work.

An instrument made specifically for threading pipes:

Utilizing the master’s preferences and the type of thread as a guide will help ensure that the correct tool is selected without error.

A die is used to apply the external thread, and a tap is used to apply the internal thread.

Features

A screw lathe was first introduced in Britain two centuries ago, at the time of threading. G. Maudsley, an inventor, figured out how to create exact threads and created a micrometer, a tool that measures them to within 0.0001 inches.

Concurrently, D. Whitworth, a mechanical engineer, designed the first helical thread profile and suggested a set of guidelines for it. The Whitworth thread, which bears his name, has been invented since then. It serves as the foundation for numerous national standards.

Although the precise date of the thread’s appearance is lost to history, the application date can be seen as the start of industrial production.

The primary characteristic of threading is that the tool used to execute it needs to be made of a material harder than the element that needs to be cut, and designs containing even harder elements should be used to manufacture the tool.

There are a plethora of options available these days for cutting pipe threads.

Making the appropriate choice is all that matters. If high-quality supplies and equipment are used, along with the directions and threading technology, good results are assured.

When cutting thread, it is preferable to use a high-quality tool because a cheap one is not likely to last very long.

Most piping systems in use today are composed of plastic. Structures must frequently be fastened using metal and plastic connecting components. These fasteners, also known as combined fasteners, are a fairly common solution in the home. One kind of metal or plastic pipe is typically used in modern communication systems. On the other hand, using a combined construction makes sense in some situations.

Systems that combine HDPE and metal elements are installed using a variety of connection techniques, such as flanged and threaded threads.

Pipes up to 40 mm in diameter are connected using a threaded method. For pipes with a larger diameter, where tightening the threading is not possible, flange connections are utilized.

Threaded pipe fitting

Flange connection for pipes

Fittings that are specifically made for this purpose are used to connect a polypropylene pipe to a metal pipe. These are joints with a plastic socket on one side and a metal thread on the other. Special complex fittings are used to create multiple combined connections.

Types of pipe thread tapping tools

Since pipe plugs are still widely used, producers produce a variety of goods:

• Simple hand-held products
• Attachments with ratchet
• Electric taps

What distinguishes the various products, and which one is the best to use to cut threads in pipes?

1. Simple cluppers are ordinary dies fixed in a holder (base). Such a die can be used both together with a handle and separately. The device can be rotated with a handle or with a gas wrench. It is only reasonable to use a simple pipe club when a single thread is to be tapped Handheld ratchet with two handles and a regulator
2. Ratchet tool. For those who wish to have in their arsenal an indispensable thread-cutting tool, it is recommended to purchase a device with a ratchet. Usually such a wrench is sold in a set, which contains various diameters of dies or bits: ½, ¾, 1, 2 inches, etc.п. The advantage of the ratchet is that it simplifies the process of using the tool. If it is necessary to cut the thread on the pipe with a ratchet, it can be done with one hand, making simple reciprocating movements Ratchet hook: an easy-to-use tool
3. Electric clapper – this type of tool is effective when you need to cut threads on pipes in large quantities. The main disadvantage of this type of tool is its exorbitant cost, which is about 25 thousand rubles. The design of the electric tapping tool is based on an electric motor capable of high torque and low revolutions. Electric device resembles the appearance of a bolgarka, only instead of a circle, a die is installed in the spindle to cut threads of the appropriate diameter of the pipe Electric tapping tool for thread cutting

Purchasing an electric club is an option if you need to quickly cut threads on pipe, but it won’t be a wise financial decision. The primary benefit of both manual and electric ratchets is the ability to thread pipes that are buried in the ground or fixed next to walls. It is not required to take the steel water or heating pipes apart in order to cut the threads. In order to accomplish this, you must grasp the tool and rapidly form a spiral connection.

Cutting with a hand tapping tool

It is advised to use a handheld club for cutting in the home workshop. The following characteristics of such a procedure should be highlighted:

1. The working part is mounted in a special holder in the form of a ratchet. It significantly simplifies the process of threading coils on the pipe surface.
2. You can start by cleaning the pipe. It should be taken into account that it is possible to cut coils only if there are no strong defects.
3. The surface is scraped down to the metal until it begins to shine.
4. The outer edge is machined to obtain a chamfer. This allows the tool to enter the pipe.
5. The surface is treated with technical petroleum jelly. It reduces the degree of friction and makes the tool run more smoothly.
6. The pipe is clamped in a vise, it can also be held with a gas wrench. It is important to exclude the possibility of inclination or displacement of the pipe when it is subjected to a high load.

Punching with a hand held device

Making multiple turns in a clockwise direction and then the opposite direction is part of the task. The purpose of this is to get chips out of the cutting zone.

Cutting with an electric club

Apart from hand tools, electric tools are also commonly used. This version has the benefit of high productivity. The following characteristics of the work in its application:

1. The part to be machined is carefully prepared.
2. The workpiece is securely fastened.
3. The mechanism is fixed at the starting point.
4. Check the free running of the guide rails and the direction of rotation of the cutting part.
5. The first turns are cut in jogging mode.

The tool has basic parameters that can be adjusted, like the cut’s length. Its functionality and other operating characteristics determine the specifics of use.

Versions

Pipe threads are used in split connections of pipelines intended for pumping liquid and gaseous working media in compliance with GOST 6111. In addition, it can be conical in comparison to water-gas pipes (GOST 3262), which makes sense given how convenient it is to screw or screw connecting parts. The taper angle, which is dependent on the thread’s diameter and pitch, cannot be less than 26° or the connection may unscrew itself. The taper angle is 60° at the apex of the tapered thread profile.

The apex of the thread profile rounds off to 10% of its radius in standard threading techniques, a feature common to all pipe threads, metric and inch. This is because, for pipes of any kind and grade, cutting pipe threads is a convenient process that also reduces internal stresses on a relatively small body of metal.

Metric pipe threads, both conical and cylindrical, are also covered by GOST 6357, though in actual use they are less common. The cylindrical thread profile has an inclination angle of 55°, increasing the number of turns on the same cutting section. Although the tightness increases, this makes connecting the pipeline’s parts more labor-intensive.

Other thread types, such as trapezoidal and thrust, are not cut on pipes because they cause more stress concentrators to form, which severely weaken the material’s cross-section.

Device

Steel with a high yield strength makes up the dies. It must be stronger than the surface that needs to be machined in order to thread. It is not necessary for the entire tool to be composed of high-quality steel, though. It is only necessary to cut the area that comes into direct contact with softer alloys.

With the clapper, this is precisely what is realized. Because it is made of more costly and durable steel and only has a cutter, the product ends up being less expensive. Other variations from the die include:

• There is a guide part;
• Longer cutters.

In other words, a club is a manual tool used for precise thread cutting. Usually utilized for machining pipes, but it can also be applied to a suitable rounded workpiece.

Pipe threading set and how to use it

Investing in a specialized set for pipes can greatly simplify the threading process. It’s perfect for use around the house. One such tool is a club, which is essentially a modified die that is used in conjunction with a ratchet and a guide. There are several accessories that can be part of the set:

1. Monolithic are represented by a cylindrical shaped body with an internal hole. The kit also includes a special die holder for work.
2. Sliding ones consist of cutters, the distance between which can be adjusted if necessary. It is used to cut a threaded surface in several passes, due to which the quality is improved.

The diameter of the pipe and the thread’s direction are taken into consideration when choosing the blade. The following characteristics of the tapping process:

1. A special tool called a club is installed in the ratchet.
2. Oil is also applied to the cutting part, which simplifies the movement of the working part.
3. A guide is installed on the edge of the processed pipe.
4. The ratchet rotates around the axis, due to which the thread is formed.
5. During machining, oil is added from time to time.

Pipe threading set

It is important to consider that the device may become blunt after extended use. For this reason, it’s essential to keep an eye on the state of the cutting edge.

Rules of use of the tool

Once used several times, basic guidelines should be followed:

1. Replace worn parts in a timely manner.
2. When cutting threads, it is obligatory to use grease. It will facilitate the cutting process, provide cooling of the working surface, increasing the service life.
3. Regularly remove chips from the surface. To do this, periodically rotate in the direction opposite to cutting.

Should a cutter break, there’s always the option to buy replacements. To ensure that they fit in the seats, it is essential to have their samples before making a purchase.

Investing in a club is a smart move for both professionals offering services to the general public and organizations, as well as for individuals doing repairs around the house. You can carry out the installation of new pipelines and the restoration of old ones with quality using an inexpensive, user-friendly tool.

On stainless steel pipe

Stainless steel is frequently utilized in the production of pipes. Its exceptional strength and corrosion resistance define it. However, the degree of machinability decreases with the number of alloying elements present. For this reason, threading can be very difficult.

With liberal application of lubricant, the cutting process can be made simpler. Selecting a die or tap composed of a material that is resistant to wear and won’t dull during processing is also essential.

In conclusion, creating threads on pipe surfaces does not require any particular knowledge or equipment.

It is crucial to make sure there is lubricant present and to use the selected threading mechanism correctly. It should be remembered that not enough lubricant can cause the taps or die to jam.

Procedure for cutting external threads on a water pipe

Creating threads

Using a grinder, a section of the water pipe with an old thread or a corroded section is first removed.

A gas wrench or a vise is used to firmly fasten the pipe section after marking in order to create a quality cut that ensures the ease of all ensuing operations. The prepared section of pipe is then given a thin chamfer cut on it, which greatly facilitates turning the die. To make it easier to slide along the threads, machine oil is applied to the threading area.

The die holder rotates in a clockwise direction while threading, but after a few threads are formed, the rotational direction is reversed. By employing this method, spent metal shavings can be kept out of the working area.

Putting up a riser pipe

The majority of domestic pipe networks have a standard that states that the threaded connection length should not exceed 1 cm. Following the threading process, metal shavings are removed from the machined area and it is then carefully wiped with a cloth or rag.

Classification of pipe threads

In the realm of plumbing operations, the word "pipe" has a special status. This term is categorized in relation to a set of standards that specify the requirements for joining different sanitary structure components.

Since water and sewage systems frequently use pipe threads, threading—either manually or automatically—is a practice that is frequently applicable.

For instance, a numerical value that represents the pipe’s standard passing diameter—rather than the thread’s actual diameter—is used to identify the size of pipe threads.

In real life, pipe threads are used:

• cylindrical (G/BSPP),
• tapered (R/BSPT),
• round for shut-off fittings (Kr),
• inch cylindrical (American standard) NPSM),
• inch cone (American standard NPT).

It is advised that the locksmith, whose primary area of work is residential, use the traditional classification of pipe threads into two primary categories as a starting point:

The home plumber who looks after the piping systems and plumbing equipment in homes most frequently deals with these two kinds.

How to use correctly

Since the manual clubs always have operating recommendations attached to them, we will discuss the manual clubs.

Using a portable club

Simply adhere to the following very basic guidelines to get a longer service life:

• Replace worn parts in time;
• Periodically lubricate the hand club with a lubricant aimed at cooling the cutters. This prevents them from overheating and deforming.
• Correctly select the size of pipes and tools. Here"s the thing: a handheld club can be used not only to cut new threads, but also to restore old threads. If the size of the tool is not correct, the threading process will cause a lot of friction, which will lead to severe heating.

Conclusions: These cover the majority of the important points. Furthermore, it should be mentioned that operating these kinds of devices is fairly simple. If it’s a ratchet, all you need to do is position everything correctly and then begin tapping the screw without jerking, occasionally moving in the opposite direction. The tool’s accuracy and quality won’t change with prolonged, careful use, which will preserve its functionality.

Threading with a die

How should a pipe threader be used to thread a pipe? There are sliding and round versions of the dies. The diameter of a round die can vary based on the pipe’s diameter. Regarding the sliding models, this all-purpose tool allows for the processing of pipes with varying diameters; for added convenience, it comes with a unique holder. Diets are very popular because they are inexpensive. The above-described procedure is followed to prepare the pipe before beginning work. Also read: "."

The following plan is suggested in order to complete the task of cutting threads on the pipe using a die:

• Selecting with a caliper a suitable die with a suitable diameter.
• Lubrication of the tool and the treated area of the pipe with any lubricant.
• Locking the die inside a special holder. The fastening of the threaded fishing lines (dies) in the holder must be very strong. If this condition is not met, there is a skew in the application of threads, which makes the place of connection very unreliable, up to the appearance of leaks.
• Rotation of the die holder in the correct direction. After making several rotations, the same procedure as with the club is performed: this way it is possible to remove the shavings that have been formed. For this purpose, the tool must be unscrewed back slightly.
• At the end of the work, the tool and the pipe should be cleaned from the lubricating material.

Roughing dies are used in the first stage to create a clean cut through the pipe; however, in this instance, thread accuracy is very small. The last threading is done with a finishing die.

Tools

In order to complete the task, all required cutting tools and equipment must be ready. The pipe threading set for manual use will vary depending on the situation, but it usually consists of dies, a club, and a holder with a ratchet. A pipe cutter, gas wrench, file, hacksaw, bolt cutter, lubricants, and other tools are also included in the kit. A power tool is an option for people who do not want to use the antiquated classical method.

The quality of the tool being used and getting ready for work are the primary requirements.

Die sets are used to facilitate the actual cutting process. While some are sliced on both sides, others are only sliced on one.

The set may also include multiple taps with varying slit depths for internal threading. Some are intended for finishing, while others are meant to roughen the pipe’s interior surface. This apparatus is depicted as a screw featuring chip grooves. The tail portion is used to secure it in the collars.

Internal threading requires the tap to be used in multiple steps. The quantity of them varies according to the material being handled. For example, specific sets of multiple taps are available for threading in titanium alloys.

Threads of different shapes can be realized on pipes using a die, runner, or lerka. It’s a steel nut with waste-receptacle grooves—specific holes—inside the cutting base. The dies are square, round, hexagonal, and tubular. They can have solid, sliced, or sliding body modifications.

Semi-plaques, also known as sliding (prismatic) models, are fastened to the club using screws and a unique gasket called a drying block. In order to distribute the pressure on the screw evenly, this is required. Threads that are circular, tapered, cylindrical, or metric can be threaded using the dies. Special collars and chucks are the plug’s component parts, which are used to attach it to the frame body.

The punch is made up of a frame that holds the dies, or cutting elements, in place. Four steel dies are included with every mandrel. Additionally, a unique ratchet handle is attached to the plug. While multiple dies can be placed inside the club, only one die can be placed inside the die holder. The runners’ cutting mechanism can cut two different kinds of threads: 0.5 – 1 ¼ and 1 ½ – 2 in.

The handheld club is typically employed for pipe cutting with a small diameter. Their unique handle-holder completes them. Also, they can be utilized with an appropriate pipe wrench. It is compact, straightforward, and simple to operate.

An adaptation of the toothed mechanism design for larger threads than one inch in diameter is a plug with a ratchet and holder. The ratchet is an essential piece of equipment. Ratchets that can be used with either hand are useful when working in tight spaces, such as those next to walls. Reciprocating thread cutting is made possible by the ratchet lever, which quickly removes the club from the thread by cranking in the opposite direction.

In actual use, Maevsky, oblique, and regular plugs are utilized.

Because of the adjustable spacing between the sliding dies, the club is also known as an oblique club. This indicates the diameter of the thread. These kinds of designs are the most user-friendly.

Mayevsky plugs, which are used to realize pipe threads, have a more intricate design. They are specifically designed for thread diameters up to two inches and come with three sets of interchangeable dies. These kinds of designs are employed for threading small-diameter pipes.

Large diameter pipe threading is done on an industrial scale. For instance, a specialized machine tool is required to cut a seamless pipe with a diameter of 219 mm. Columns, or casing pipes, are only cut on specialized equipment in accordance with all safety protocols and under particular circumstances.

Advantages of clamping tools

As was previously mentioned, this tool’s features are used to thread pipes. However, there are other benefits to such a set besides just being simple to use. For instance, if you are familiar with using a die to cut threads on a pipe, you can handle this task with ease when using a cluppe. Additional benefits include neat threads, an easy-to-use pipe threader, fast die cutter changes, and lightweight design.

The next factor is particularly important to consider. It is not inexpensive tool steel that was used to create the die. But the only cutters that ought to be more durable are the ones that handle the majority of the work! The cost of a set of tapping tools is lowered by the absence of pricey, non-functional parts, which also lowers the cost of thread cutting stainless steel pipe. As a result, home masters who are proficient in money management favor this specific instrument.

Using a club will greatly simplify the process of threading.

A set of dies for thread cutting on pipes with diameters of 50, 38, 32, 25, 20, and 15 mm is included with the purchase of these products. 1, 2, 3, or 4 are the corresponding numbers for each of them. The numbers assigned to each slot on the clapper’s body also correspond to the cutters’ flats, which are used to cut the threads in the pipe. In order to optimize productivity in challenging locations, it is advised to acquire specialized equipment in tandem with the club.

Such a tool is now available on the market and comes with both an electric and manual drive. Thus, the question of how to more effectively cut threads on pipe may come up.

Information that is helpful! Clubs can be purchased from specialist brick-and-mortar and internet retailers. The latter are particularly practical since you can acquire a good set for threading pipes without having to leave your house.

Expert locksmiths with extensive pipe-threading knowledge prefer to use electric tapping tools. However, these gadgets are more expensive. Therefore, buying a set of tools with a manual drive is more cost-effective if thread cutting on pipe is to be done once.

Step-by-step instructions for thread cutting with a die

The most typical is referred to as a die of different kinds. It is one of the instruments required to cut coils. We will highlight the following aspects of it:

1. A die looks like a nut made of hardened steel. There are flower-shaped holes on the end faces. To ensure mechanical processing, the faces are presented with sharp cutting edges. Due to the lobe shape, chip removal from the cutting zone is ensured.
2. There are holes in the body for the handle to be installed. They are located on the sides, thus ensuring a uniform impact.

The die’s ease of use has led to its rise in popularity. The following are recommendations for its use:

1. At the time of processing the pipe should be vertically positioned. In this case, it is fixed with the help of a vise.
2. Surface cleaning is recommended, as well as chamfering.
3. Oil should be applied to the pipe, which will make it easier for the die to run on the pipe.
4. It should be taken into account that the die should be positioned strictly vertically. Even a deviation of only 10 degrees will result in a reduction in the quality of the resulting coils.
5. The handle should be turned clockwise.
6. In order to improve the quality of the obtained surface it is necessary to make one reverse turn after two turns, which ensures the removal of metal residues from the cutting part.

Using a die to cut thread

Oil should be periodically applied to the working part and the pipe during the task. Cutting becomes smoother and easier with lubricants.

Parameters to be taken into account when choosing a device

1. The purposes for which it will be used.

If you intend to use the manual club sparingly or never, it’s worth investing in because it’s lightweight and easy to move from one place to another.

Using the ratchet in difficult-to-reach areas is essential.

The electric gadget is intended for daily usage. In this instance, increased labor productivity will make the cost of acquisition worthwhile.

2. The set’s interchangeable cutters enable prompt replacement of the damaged ones. While "dull" cutters need a lot of work, working with broken cutters results in scrap.

3. Cutter material.

High-quality parts are composed of chrome-vanadium or alloy steel, which will guarantee the tool’s dependable operation for an extended period of time. You can purchase the tool for less money if you intend to use it for no more than ten operations.

4. It is more profitable to purchase sets of thread cutters rather than individual tools when cutting threads of various sizes.

5. The product’s longevity and operational safety are directly impacted by the ratchet mechanism’s quality. The ratchet stopper’s diameter ought to be adequate to keep it from shattering even when strong forces are applied.

Tool composition

Set of hand clamps

Pipe billets of any size can be threaded using an electromechanical threading set known as a "club" in combination with a set of radial dies of different diameters. For thread cutting, you’ll need the following supplies and equipment in addition to the device:

1. Taps for fast cutting of internal threads.
2. Mechanical vise used for fixing pipe blanks.
3. A grinder designed for preparing threading areas.
4. Lubricating oils.

We want to make sure you know that you can only use the electric grinder while wearing safety glasses and gloves.

How to do it correctly with a club

The following structural scheme should be followed when carrying out the process.

1. You need to find the right blade with the right cross section. A caliper should be used to make sure that the equipment is correctly selected.
2. Prepared section of the pipe and the inner surfaces of the tongs should be lubricated with machine oil.
3. Insert the tapping tool into the metal pipe, using the holder (it is included in the kit for cutting grooves on pipes).
4. If you are carrying out the initial assembly of the pipeline Or decided to install a faucet for a drinking water filter (written ), then the hollow object should be fixed in a vise – this will facilitate the work. When reconstructing a water main, threading is done directly on the installed pipe.
5. After all the preparatory measures have been completed, it is necessary to enter the pipe opening with a tap of the appropriate diameter, and then rotate its base clockwise. For this purpose, use a screwdriver, which is included in the set of tools.

There are chips on the grooves that need to be cleaned off.

How do I?

You must turn a few times around the pipe before turning the fixture ninety degrees in the other direction.

Use a fresh rag to remove any oil residue after finishing the task.

How to properly cut coils on a water pipe

You can cut on the workbench when installing a new section of the heating (water supply) system. A special vise is used to place the workpiece strictly horizontally (or vertically).

Impressive torque can be produced even by hand tools, like a screwdriver with a die or a thread tapping tool. Consequently, the water pipe needs to be securely clamped in order for you to be able to cut the thread with your hands.

The threads can be ruined if the workpiece is turned. Many do-it-yourselfers use written-off calipers from old lathes instead of a vise with a dovetail clamp for fixing.

After taking measurements, you cut the pipe while keeping in mind how the die (club) entry is processed at the end. The threaded connection’s length is then indicated; for instance, a bend needs to be made on the heating pipe where it connects to the radiator.

The end is machined with a file under a taper for regular club or die entry before you begin cutting.

If this isn’t done, the entry will be made skew, and the thread will tear off after a few turns. The damaged section of the pipe cannot be repaired; it must be cut.

Working with a die

This tool is useful for cutting coils on pipe that have a radius of 50 cm and no objects around them. There should be a screwdriver slot, either on the side or the end.

Naturally, accessing the piping system isn’t always feasible, particularly when fixing things. Certain single-handle collar models, known as ratchets, can be used to cut threads along the wall.

However, the fixture cannot be held precisely on the axis due to the die’s very design. One lever means that there is no way for the force on the cutters to be uniform, so there is a chance of screwing up the coils.

For this reason, you should practice on some extraneous pipe several times before using the ratchet to tap threads.

Crucial! The proper preparation of the pipe is especially crucial when using a die (lerka).

A poorly chamfered end or a drop from welding can throw the die off straight if the club is willing to "forgive" a few mistakes. Threading is done in two to three passes using dies with varying cutter depths.

First, the first layer is removed by marking with number 1. The coils were then cut through by #2 (and #3) to the working depth.

A video that shows you how to thread a pipe with a die instead of a club.

Working with a club

A lot of inexperienced artisans are unable to thread close to the wall. The club’s design allows it to self-center with respect to the pipe’s axis, which eliminates tool misalignment—exactly what it is ideal for.

Skilled artisans advise using a club to tap any pipe thread because it makes the process easier and enhances the external thread quality.

Because the club’s cutters are interchangeable, using it is simple. In other words, the cage’s material can be made of comparatively pliable, soft metal, and the cutters can be made of hard alloy steel.

During the cutting process, the cutters’ positions can be changed, enabling primary, secondary, and finishing passes to be performed without taking the tool apart. In other words, all you have to do is tighten the parts that are being cut, each time deepening the threads.

Because of the way the cutters are arranged, maintaining straightness along the pipe axis is simple. There is very little chance of a coil breaking. Consequently, even a novice can handle using the clapper in difficult-to-reach areas.

There are electric versions of the club that produce a strong torque on the cutter block with the aid of a reducer. All the user has to do is move the tool along the pipe.

Grease is applied to the prepped workpiece, the first pass depth is adjusted, and the power is activated. The chip removal is automatically monitored; there is no need to perform reverse rotations as with the collar.

It doesn’t matter if you are installing a heating system or fixing the water supply. Such a tool allows the work to be completed much more quickly. Naturally, not for nothing: an electric club is rather expensive.

Using an electric tapping tool to thread

In the article "How to Properly Thread a Water Pipe," we"ll guide you through the essential steps to ensure a secure and leak-free connection for your plumbing needs. Threading a water pipe correctly is crucial to prevent water leaks and ensure the efficient flow of water throughout your house. We"ll cover the tools you need, the proper technique for threading, and important safety precautions to keep in mind. Whether you"re a DIY enthusiast or a professional plumber, mastering this skill will save you time, money, and headaches in the long run. So let"s dive in and learn how to thread a water pipe like a pro!

The basics of plumbing repair

Few people have considered how to connect a private home’s water supply inlet.

• pipes,
• valves,
• valves,
• taps and other components.

It is put together using threaded connections to form a single system.

There is a thread and it doesn’t take a long time to replace an old part with a new one.

These situations arise occasionally when you need to replace a worn-out component (like a pipe) that lacks grooves.

In this situation, what should I do?

The way out of this situation is very simple – with your own hands to cut threads. It is ideal if you have the option of using a lathe.

However, not every home handyman has access to such tools.

It requires certain knowledge and abilities to operate, and it is pricey.

One of the two kinds of tools made for cutting grooves can be used to thread a pipe, as in the case of connecting a membrane tank for water supply (as stated here):

This tool is used to cut threads in water and sewer pipes, which are used in private and multi-story buildings’ utilities (read why a water trap is necessary).

Note: It will be extremely challenging for you to work with a lerka if you have no prior experience in this field. Since a defect will always result from even the smallest misalignment of the tool

In this instance, using a screwdriver is the best option because it makes cutting easier and there is a guide, which is a crucial component in the design. Practice on an unnecessary piece of hollow object to gain some experience so that you don’t ruin a water pipe.

When learning a new skill, practice on a hollow object that you don’t need to avoid damaging the water pipe.

Let’s now attempt to review the main points of the threading process:

• when grooving the pipes, A helical surface is formed on the outside of the hollow object;
• screw plane It plays the role of a connecting element that rotates dimensionally around the bending axis;
• thread pitch corresponds to one complete turn.

The thread must be cut so that the pitch precisely matches the pitch of the mating parts for the mating water pipe location to be watertight, robust, and able to withstand high system pressure.

Methods

When it comes to threading, consideration is given to the diameter at the outer, middle, and inner edges of the coil, along with the elements and angle of the profile (cross-section of the coil). The thread is classified into triangular, trapezoidal, rectangular, and other types based on the profile.

Gas and water pipes are threaded using cylindrical pipe threads. There is partial threading on the final two turns. This is a runaway that is required for a secure pipe connection. Certain kinds of dies are used to run off. Threads are measured in inches, and pipe diameter is measured in millimeters.

There are two types of threading: left- and right-hand, internal and external. Nuts are screwed to the left side in the left-handed version and the right side in the right-handed version. There are three different types of threads: fastener, running, and fastener-sealing, depending on how they are used. At home, the latter variety is utilized for threading pipes.

Both the thread’s depth and the spacing between its strands are known as the "thread pitch." They all adhere to the same principle—the deeper, the stronger—despite having different configurations.

Threading can be done in a number of ways, including with a threading machine, an automatic electric club, and a club. Dies installed in a club’s frame are used for manual external threading. Designs for sliding dies and one-piece dies are used. The cutting diameter is adjusted with the aid of split constructions.

Round dies are installed with special screws on the collar, and sliding dies are arranged in accordance with the numbered values. Next, the dies are adjusted. A dryer rod gasket is inserted between the sliding dies and the screw.

Taps are used to assist with internal threading. They use their tool to drill holes in a metal pipe while closely following precise calculations. A good threading requires at least three revolutions.

The internal thread is used in the same reciprocating manner as the external thread, i.e., two steps forward and one step back. Using a roughing tap is the first method. There is just one risk associated with it. After that, the process is repeated using a medium tap that carries two risks. A finishing tool with three dots on the end completes the cutting.

The tool needs to be taken out and cleaned on a regular basis when threading deep surfaces. Long taps are used in blind holes, and lubricating emulsion is required.

Threading pipes is made much simpler by automatic electric tapping machines. They are made up of a set of dies with varying calibres and modified reducers. They run off the main power supply and are known for their high productivity. Despite all of its benefits, the tool has drawbacks. For instance, an electric club with a 1kW power source has a considerable kickback, so it is secured with a clamping clamp.

The threading machine is typically utilized in large workshops and on an industrial scale. The machine’s benefits over manual and electric tools include minimal human intervention, high productivity, and precise threading.

There are three types of pipe threading machines: manual, electric, and automatic. Manual is used at home because it is lightweight, portable, and only weighs 50 kg. However, it is not appropriate for pipes with a large diameter. Small workshops can benefit from electric machines, while automatic versions are commonly employed in production settings because of their substantial size and exceptional productivity.

Certain pipe types can only be threaded in an industrial setting. For instance, threading a carbon pipe with a 32 mm diameter requires treating its surface with a specific compound.

The material is disposed of after the task is completed. Cutting should be done with basic skills and knowledge in this area because if the product has thread defects, it cannot be used.

Purpose of a pipe threader

Threading is a necessary part of pipeline construction that allows segments of the pipe to be connected. Because threading offers a dependable and superior connection, this kind of connection remains relevant over time.

This rule does not, however, hold true in every circumstance. For instance, polypropylene pipes are welded together, while polyethylene pipes are joined with specialized compression fittings. These connection techniques have long been shown to be the most effective ones available.

But even these effective techniques for joining pipes have some significant drawbacks in addition to their ease of use and simplicity:

1. Fear of high temperatures. The maximum temperature at which polypropylene and metal-plastic pipes can function is 95 degrees Celsius. Of course, on paper, this standard is available and can even be observed, but there are not rare cases when hotter liquids are run through the pipes – for example, when heating houses in very cold winters. As a result of such an impact, the pipe is destroyed, with all the ensuing consequences. What about polyethylene pipes, which begin to deform as soon as the temperature reaches 40 degrees Celsius.
2. Low mechanical strength. When laying plastic pipes, it is necessary to take into account their ability to withstand physical stresses. For example, plastic products are not suitable for installation of pipelines under roads or in areas with high traffic – they are very easy to damage even by accidental impact.

As a result, we can conclude that using only metal pipes in specific circumstances is feasible, but they still need to be sealed against corrosion.

There are only two ways that metal pipes can be hermetically connected:

• Welding;
• Threaded connection.

It’s not always appropriate, but welding is a good option. One of the causes is that welding weakens the pipe’s zinc coating, which leaves it instantly vulnerable to corrosive forces. Ultimately, there’s just the thread, and it has no drawback.

Types of clamps

Plugs are fairly basic, comparable tools, though they do differ slightly from one another. They are not the same:

• by thread pitch or thread direction;
• on the convenience of work, for example, in hard-to-reach places;
• By size and other parameters.

Nonetheless, the principle of operation is the primary characteristic that allows for their division. Are unique:

• hand tool;
• electric.

The following characteristics are present in both types:

• the ability to make a thread on a pipe even with a very large diameter;
• provided the necessary skills – accuracy of work.

Manual

A portable club can be held by:

1. From two rods made of metal. They are held and rotated during work. This option is more common than the others.
2. Single handles. They can be operated comfortably with one hand. This allows for better use in difficult to access places. They are less common.
3. Sometimes you can find a ratchet-style holder.

In the latter instance, the design makes the work process—rotation—easier. But it’s important to keep in mind the ratchet’s drawbacks:

1. In any mechanism, there is a regularity: the more complex it is, the faster it breaks down.
2. On sale are almost always Chinese cheap models. The quality of the material is low.
3. Certain types of pipe alloys are stronger. Instead of cutting, the ratchet can break itself.

Low-cost models are frequently offered without a holder. For example, an appropriately sized gas wrench can be used to replace it.

Handheld clubs exist based on the kind of coils:

• single thread – the thread is made with a single screw thread;
• multi-turn – two or more.

They are not less than electric models in terms of thread quality, and they require little maintenance. Non-professionals appreciate these attributes because they let you do basic household tasks without incurring additional costs. Frequently used to revive old threads as well as create new ones.

Electric

Professionals use the electric version. Almost any size pipe can be used with it. The workflow has been significantly streamlined. It comes down to just installing the clubhead and mending the pipe. Benefits compared to manual

1. It is not necessary to spend a lot of effort. Products have low power, which does not prevent them from performing even heavy work in difficult cases.
2. Time is saved, as cutting is much faster.

Additionally, there are flaws:

1. The electric club is noticeably heavier than the manual one and takes up more space.
2. It is much more difficult to work in difficult to access places. Also explained by the dimensions.
3. Electricity is required.
4. Application can be weather dependent. For example, it is not recommended to use electric devices in the rain.

Selection criteria for a pipe tapping machine

At the moment, the industry has developed to such an extent that clubs are sold in a huge range and the most different modifications. Russian markets are full of a variety of products, including Western-made products, which in most cases are of higher quality. As for specific prices, we will talk about them a little later, we will only note that they, as well as the choice, have a considerable variation. Choosing for yourself the tool described in this article, it is mandatory to consult with a qualified specialist in advance. The cheapest tool in any case, it is better not to give preference, as well as the first hit retail outlet. Subsequently, such a club is likely to surprise you unpleasantly – both with its "outstanding" capabilities and further failure. At the same time, the price (especially in the case of buying a pipe club) increases along with the quality of the tool.

Of course, the replaceable cutters are another crucial factor. Ultimately, the ability to modify these components implies that you won’t need to replace the device as a whole down the road. However, it is also possible that new cutters won’t fit the club; for this reason, it is advised to purchase them in addition to the equipment.

Ultimately, take into consideration the pipe’s manufacturing material when choosing a drill bit for threading. Take note of the precise material that the cutters are made of.

Alloy steel is, of course, the most dependable (and consequently, the most preferred) choice.

What you should know about threading

• Depth – distance from the thread base to the pipe end.
• Profile and its angle – the cross-section at the coil, which is made in the form of a triangle, rectangle and other shapes. When the side edges of the coils intersect, an angle is formed.
• pitch – the distance that is formed between the pipe tops or nearby coils.

Important: The depth and number of turns per unit of threads increase with increasing pitch, and vice versa.

The inch, which is represented by a triangle, is used to join parts of water and occasionally heating pipes.

A smaller pitch version of the inch thread is called cylindrical.

The profile’s rounded upper edge has a cylinder-like appearance. Below is an illustration of an external cylindrical thread pattern:

Tapered: This kind enables a hermetic connection, which is particularly important for sealing materials.

Spigots with small diameters are called metric. It may be trapezoidal, with sides that resemble a trapezium and an external angle of thirty degrees. Bolted connections can also employ rectangular thread since it improves the fixation’s dependability. This is a metric thread scheme that resembles an equilateral triangle:

• Inch – is represented as a triangle and is used when assembling elements of a water pipe and sometimes a heating pipe.
• Cylindrical – A variant of the inch thread that has a smaller pitch. The smoothed upper edge of the profile resembles a cylinder. An example of the scheme of external cylindrical thread is shown below:
• Conical – the type allows to obtain a hermetic connection, which is especially important when using sealing materials.
• Metric – this type is used for small diameter sockets. Can be trapezoidal – the external angle is made in 30 degrees, and the sides of the coils resemble a trapezium. For bolted connections, rectangular threads can also be used, as they make the fixation more secure. Here is a scheme of metric thread, which has the form of an equilateral triangle:

Features of work with hand tools

Hand tools are necessary for preparatory work because they are not machines. The pipe’s end needs to be flat and oriented perpendicularly to its axis. This requirement is automatically met if a pipe cutter is used to cut the pipe. After cutting with a metal hacksaw or a Bulgarian, the edges need to be filed down further. The old pipe should be threaded on the paint-free area, and the newly installed pipes should be dirt-free. Even though the pipe’s edge is already beveled, it is still advisable to trim it to create a tiny cone where the cutters will enter.

If the pipe is immediately oiled along the entire threading length, cutters will "work" better. Repeated lubrication is necessary as the tool advances.

Following the preparatory steps, the club is "slipped" onto the pipe for one or two turns of the dies’ starting cone. Even though the head has guides, it is still necessary to confirm that it is positioned correctly with respect to the pipe’s axis. After that, position the ratchet switch as needed and begin turning it in a clockwise direction (naturally for right-hand threads).

By the way, when purchasing a club, heads, and replacement cutters, it is important to consider this parameter even though it is implied by default.

It is worthwhile to press the head against the pipe for the first few turns until the dies are mostly embedded in the pipe. Following that, all of the force can be directed toward turning the clubbing tool’s handle.

Working with the club ought to be compared to rolling a regular die: two steps forward, one step back. In order to clear the working area of chips, this is necessary. You must flip the lever from forward to reverse in order to use a ratchet tap.

After cutting is complete, the heads are removed or the club is unscrewed by turning the ratchet. Next, it’s important to make sure the cut thread matches the mating portion. You can run over the tool one more time if the thread is tight (perhaps because the dies are worn out).

What is a clevis

This tool works incredibly well when installing plumbing systems. The club is essentially a familiar object to everyone (this product is popularly called "lerka"). When threading the pipe, the die has a small, cylindrical component with recesses to release swarf. Furthermore, the die features circular recesses all around it to facilitate simple clamping with the holder. The thread is cut with the aid of ridges in the tool’s inner section.

A die and a pipe club are slightly different. The tool has cutters that are fixed in place using a unique holder.

For effective heating and to avoid expensive damage, make sure your home has the right insulation and water pipe installation. You can make sure that your water pipes are threaded safely and securely, ensuring consistent water flow throughout your home, by following the right procedures.

First and foremost, it’s critical to select the appropriate size and kind of water pipes for your unique requirements. Take into account elements like the planned use of the pipes and the local water pressure. Water flow can be decreased by using pipes that are too small, and extra costs can arise from using pipes that are too large.

Next, during installation, carefully consider the arrangement and positioning of the water pipes. Planning ahead can reduce the possibility of leaks and guarantee that the pipes are readily accessible for future maintenance and repairs. Furthermore, use premium fittings and materials to prevent rust and other damage over time.

Water pipe threading requires a high degree of accuracy and precision. To make sure the pipes fit snugly, take your time measuring and cutting them. A secure connection will be formed by properly threaded pipes, preventing leaks and guaranteeing effective water flow throughout your house.

Lastly, don’t undervalue the significance of insulation. Insulating your water pipes can help keep them from freezing in the winter and reduce heat loss. This lowers the possibility of expensive damage and repairs while simultaneously increasing the efficiency of your heating system.

In conclusion, threading water pipes correctly is essential for the proper functioning of your home"s plumbing system. By choosing the right materials, planning the layout carefully, and ensuring accurate installation, you can maintain reliable water flow and prevent potential issues down the line. Additionally, proper insulation will help to improve energy efficiency and protect your pipes from damage. Investing time and effort into these steps now can save you money and headaches in the long run.
