Choose pipes for electrical wiring taking into account the characteristics of the product and building

Selecting the appropriate pipes for electrical wiring is essential for your home’s efficiency and safety. Choosing the pipes that best fit your needs can be overwhelming with so many options available. The main features of electrical wiring pipes and their relationships to various building types and environments will be covered in this guide.

The material of the pipes should be taken into consideration first and foremost. Flexible conduits, metal, and PVC are common choices. PVC pipes are appropriate for the majority of residential applications because they are inexpensive, lightweight, and corrosion-resistant. While metal pipes, like those made of aluminum or galvanized steel, are more resilient to physical harm and offer longer lifespans, their installation might be more difficult. Conduits that are flexible, such as metal or corrugated plastic tubing, are easy to install and versatile in confined areas.

The size and capacity of the pipes is another crucial aspect to take into account. It’s important to select a pipe diameter that can support the electrical load in your home because this determines how much wiring it can hold. Take into account the pipes’ insulating qualities as well. By shielding wiring from the elements—such as heat, cold, and moisture—insulated conduits can increase the longevity of your electrical system and avert safety risks.

The particular needs of your building must also be considered when choosing pipes for electrical wiring. For example, you might require pipes that adhere to specific building codes and regulations if you’re wiring a new construction or renovation project. Don’t forget to take into account things like your home’s layout, the existence of other utilities, and any potential roadblocks that might interfere with the installation process.

Lastly, remember to account for your long-term maintenance requirements as well as your budget. Although it could be tempting to go with the least expensive option, spending more money up front on high-quality pipes can save you money over time by lowering the need for replacements and repairs. Seek pipes that provide an excellent mix of performance, longevity, and affordability to guarantee the longevity and security of your electrical system.

The scope of use of pipes for electrical wiring

Ten to fifteen years ago, conductive wires were only concealed within pipes when they needed to be shielded from thermal, chemical, or mechanical impacts. When electrifying buildings with strict fire safety regulations, cables were buried at a shallow depth and the pipes were utilized to provide a general entryway into the structure.

Updated electrical wiring

Modern construction standards state that all conductive cables should be hidden in pipes with an appropriate diameter, regardless of the insulation’s thickness or the core’s section. Such a regulation not only permits the wiring’s safety but also lessens the risk of a short circuit causing fire. Pipes are utilized in residential single-family homes, apartment buildings, and industrial storage facilities. Only locations with open wiring and lax fire safety regulations may be exempt.

Pipes serve these primary purposes in electrical wiring:

  • Cable Protection from Mechanical Blows. The integrity of the wire hidden in plaster can be broken when installing hinged shelves or creating a new opening in the wall. If the wire is in the pipe, the probability of this damage will be significantly lower.
  • Moisture wiring protection. For example, if the apartment is flooded on top, the wires laid in the ceiling fall into the moist environment and if they are not protected, then in the places of connection and zones with disturbed insulation, a short circuit may occur.
  • Fire prevention. The tube will not allow fire to affect the neighboring areas or significantly limit its intensity (depending on the material of the product). In wooden houses, this is an effective way to rebuild the fire and give the owners the opportunity to prevent a fire.
  • Simplicity of repair. If the wire leading to the outlet is damaged, to restore its work, it will not be necessary to post the walls. The master will simply disconnect its end in the camshaft and, having attached the edge of the new cable to the free end, will reach them to the outlet along the pipe. As a result, the old cable will fully stretch, and the new one will only have to be connected to the contacts. All work will take no more than 30-40 minutes and will cost ten times cheaper than remaking the entire wall.

Varieties of pipes

Pipes are separated into two categories based on the material: metal (made of steel, copper, and aluminum) and plastic (made of PVC, PND). These materials can all be used to make straight, smooth pipes as well as corrugated pipes.

Smooth steel

The most conventional, albeit time-consuming, method of shielding wiring from mechanical stress, pollution, and UV light is to use steel pipe. They are most frequently utilized during the building’s electrical supply, floor ceiling crossings, and floor wiring installation. According to GOST 3262–75, combustible, lubricant, varnishes, acetone-containing substances, and other explosive or fire-hazardous materials are installed in steel pipes used in agriculture and industry’s wiring in warehouses.

The pipe of the matching diameter is chosen for each segment of the wire.

Installing these pipes is advised by GOST 10704–91 and GOST 10705–80 since they are still thought to be the most dependable:

  • in all types of children"s institutions;
  • attics of buildings of any purpose;
  • in buildings of a cultural and entertaining nature;
  • Histines and sanatoriums;
  • in hot industrial workshops;
  • behind suspended ceilings and in complex foundations for equipment.

The trunk is installed in the explosive rooms using coupling-converting connections and thick-walled pipes with internal galvanizing. It is permissible to use thin-walled steel pipes connected by sleeves and cuffs if the only threat is fire (not explosion). However, you should select pipes with a coupling-convertible connection and seal when it’s also essential to shield the wires from dust, dangerous fumes, or excessive humidity.

It is essential to choose products with a protective coating or paint steel pipes with Kuzbasspak after installation because they are prone to corrosion. If the pipe is left outside, this type of painting needs to be updated every few years. The product works well for screeding the floor and adding wall thickness beneath plaster.

Features of installation

A brain-moth joint’s pipes can only be mounted by a skilled welder with the right amount of tolerance. The pipeline’s bends are the result of the complete corner elements being attached (either by welding or on thread). The site’s two bends should not be longer than five meters, and a distribution box must be placed after them.

Wire connections are made in distribution boxes.

The process of installing steel pipes for wiring:

  1. pipe cutting, according to the sketch;
  2. equipment of blanks in nodes and blocks;
  3. cleaning the inner surface of the pipes (if there is no galvanizing);
  4. Painting or varnishing of pipes if they are laid outdoors;
  5. Step -by -step assembly of the system and an institution inside the wires.

It is necessary to mount the straight sections of an open steel pipeline at an angle towards the distribution box in order to prevent condensation and rainwater buildup on the pipes.

Advantages and disadvantages

pros Minuses
High mechanical resistance. The complexity of installation.
Suitable for explosive rooms. The need to update the paintwork.
Recommended for fire hazardous buildings. The impossibility of using cables without isolation.
Protect the wiring from dust and gases. The bending angle is limited to 90 o, the length of the straight section is 10 meters.
Increased resistance to both transverse loads and stretching. Large weight, even in thin -walled products.
The period of use is up to 50 years (depending on operating conditions). High price.

Hopound steel pipes

These products are not welded; instead, they are gathered from a strip using a mobile connection, which sets them apart from smooth steel pipes. Because of the extra stiffness ribs that are added, the resulting pipe can withstand transverse loads of up to 60 atmospheres and more. However, due to the way it was made, it is more sensitive to loads that stretch (strong tension causes the tape to spiral).

The wall thickness of corrugated pipes varies from product to product.

Its installation is easier than that of smooth pipes since corner components are not needed. The tube itself is thin and bends in any direction, even at 300. The qualification of the monster can be significantly lower than in the case of a smooth analogue because the corrugated pipe does not connect; rather, it is whole from the connection point to the camshaft.

Turns and levels with corrugation don’t cause any issues.

Furthermore, because highly alloyed steel is typically used to make steel corrugation, it is not "afraid" of moisture, fungi, or corrosion and doesn’t need special maintenance. As you can see, corrugated steel pipes are smooth to the touch, but they cost a lot more than their plastic counterparts.

Copper pipes

Steel and copper pipes are comparable in terms of weight, mechanical resistance, and numerous other aspects. However, because of their much reduced susceptibility to moisture and chemical regulators, copper and brass (rafting based on copper) products are utilized in environments that have a lot of vaporized water, such as car washes, botanical gardens, greenhouses, and bathtubs. The longest service life is offered by this option, but the cost is high.

Gorgeous open twisted wires and plumbing connections

Designers use copper pipes to create open decorative wiring because they have a very appealing appearance. A system like this appears particularly striking when combined with retardants and chandeliers made of copper, brass, or bronze (or imitations thereof). Owing to the high copper content, this type of wiring can be used to adorn the building’s facade. The greenish-blue plaque that oxidation causes to gradually appear on the metal’s surface enhances its aesthetic rather than detracting from it.

Copper pipe wiring is now a fashionable loft room accent.

Features of installation

Thin copper pipes can bend at the proper angle without necessarily needing couplings. Even though copper is more flexible than steel, mounting such a pipeline requires the expertise of a welder and equipment meant for thin-style product work. The distribution boxes’ location, the bending radius, and the straight section’s length are all constrained by the same rules that apply to steel.

Plastic pipes

Smooth-cut and corrugated pipes made of various plastic types (PVC, PND, PVD) are used for the installation of electrical cables. Although their mechanical and thermal characteristics are different, they share several characteristics:

  • Low weight that facilitates the process of laying, transportation and storage. With a large number of pipes in buildings with weak wooden floors, it is worth preferring plastic precisely because they load the constructive at home than metal.
  • Simplicity of installation. Even a beginner can cope with styling, since welding work is not required in the process and the use of connecting elements is not necessary. To attach the pipe to the base, it is enough to pull it into a special plastic clip.
  • Suitable for mounting cables without your own insulation. Metal pipes for this purpose are prohibited.
  • Low coefficient of linear expansion. This means that when heated, the pipe practically does not increase the diameter, so when laying the cable in the thickness of the wall, cracks do not appear in it.
  • Low cost compared to metal analogues.

It is permissible to lay cables underwater using plastic pipes.

Producers create products that are corrugated, hard, soft, reinforced, and suitable for a range of environments. For instance, it is advised to use harsh when installing wiring beneath plaster.

Differences of plastic pipes for wiring

Permissible temperature amplitude in the room -25 o – +60 o C -50 o – +40 o C -60 o – +40 ° C (in the accident, it is permissible +80 about C)
Stability to ultraviolet Low, the product is not used for open wiring. Low, depends on the chemical composition (some manufacturers add special additives). Low
Chemical resistance Medium, allowed for use in slagged rooms. Good, not afraid of gases. Low, easily oxidized by chemical reagents, including gaseous.
Water permeability Almost absent, suitable for underwater communications. Inserty, suitable for rooms with high humidity. Low, it is possible to lay underground, in places where significant mechanical loads are not expected.
Term of use Up to 50 years 40-50 years (depending on operating conditions). More than 50 years.

Conductive cables, telephones, alarms, and telecommunications can all be installed in residential buildings as well as industrial and administrative buildings using plastic pipes.

Steel is six times more difficult than PND pipes.

Smooth plastic pipes

Water and smooth plastic pipes are comparable for wiring.

According to Tu-6-19-215-83, PVC products are made with a length of 3 m and a diameter range of 16 mm to 50 mm (their characteristics are not regulated). Products may be used to install concealed wiring in weakly damaged areas as well as non-combustible materials. That is, between the layers of stone cotton wool, you can install the attic’s wiring in them.

It is not necessary to use PVC pipe to protect against fungus, corrosion, or mild chemical oxidizers.

Not every PVC pipe is adjacent to itself. Make sure to inspect the store’s sample before making a purchase.

Corrugated plastic pipes

There are bays that are 25, 50, 100, and 200 meters long in plastic corrugated tubes. This increases the system’s reliability by enabling the creation of wiring without needless connections. However, the use of rotary squares, tees, allotments, and connecting couplings is acceptable in highly complex schemes.

Corrugated pipes are advised for installation in wall thicknesses and difficult-to-reach areas (such as behind shelling ceilings) due to the relatively low stability of plastic under mechanical shock loads.

The selection of the diameter of the PVC pipe depending on the purpose

Purpose The diameter of the corrugated pipe,
Power circuit breakers 2.0
Power outlets 2.0
Power of lighting devices 1.6
Phone connection and alarm from 1.6
Connection of shields and decaying boxes 2.5
Ensuring the inter -story joints 4.0-5.0

Features of installation of plastic pipes

To keep the conductive wire from heating up, the cable must be inserted into the plastic pipe at least 10 centimeters below the heating pipe. If these components are not arranged parallel but rather cross at a single point, there should be a 5 cm height difference.

Concrete cannot be poured over light corrugation because the pressure causes it to distort. Search for hard.

The pipe connection point to the distribution box in the wet rooms needs to be sealed.

An illustration of how the cables are connected inside the camshaft’s plastic pipes

It is not acceptable to conceal the wire connection inside the plastic pipe. A decaying box is positioned at the junction if it turns out that the cable is longer than is required.

Specialized nuts and jumpers are used for the gaining and grounding wires.

When cutting through a plastic corrugation, take care not to cut your hands on the stretched wire inside.
