The building materials market is represented by various types of plastic, among which polyvinyl chloride is one of the most common. PVC pipes are relevant in the arrangement of electrical networks. They are used to protect wires and cables from external factors of various nature. And then we will tell you which ones are better to buy (technical characteristics and advantages of such products will also be described below).

Self-extinguishing polyvinyl chloride is used. In this variation, the raw material acquires properties due to which its use in the creation of engineering cable-supporting networks becomes simply indispensable. In addition, self-extinguishing PVC models serve as a kind of insulation for wiring, providing it with fire protection.

Plastic pipes made of polyvinyl chloride have many valuable qualities. Their advantages can be considered:

1. Ecological cleanliness and hygiene.
2. Durability (due to the strong structure of the raw materials, as well as resistance to adverse operating conditions and ultraviolet radiation, aggressive substances, mechanical pressure.)
3. Practicality during operation, because they do not require additional maintenance.
4. Ease of installation.

1. Absolutely not subject to the destructive effect of corrosion.
2. Light weight, not exerting a load on the bearing base.
3. Tightness, thanks to which the wires and cable will be protected not only from moisture, but also from the ingress of dirt, dust and other elements into the structure.
4. A small percentage of possible deformation of products.
5. Low cost.

Today, all the advantages that plastic pipes for cable laying have make such products indispensable for equipping power supply networks. Practically unparalleled, such pipes are used in the construction of residential buildings, as well as administrative and industrial buildings.

What are the types of polymer collectors

In the electrical goods market, PVC pipe is presented in various sizes and models. Initially, all products of this kind are divided into two main groups:

1. Pipes are rigid, with a smooth shell.
2. Corrugated tubes, flexible.

All products belonging to the first category are usually used outside construction objects and ceilings (open wiring). can be used directly inside structures. Hidden wiring is arranged in the corrugated pipe, which can be brought under plaster in the walls or ceiling, or in the floor - under a screed, concrete coating. This facilitates repair and dismantling, if necessary. Some corrugated flexible pipes are equipped with an additional device (steel probe) that simplifies their use. With the help of such uncomplicated equipment, it is possible to easily lead the cable inside the model and quickly mount the power supply system.

According to GOST 18599-83, another classification of plastic collectors for protecting wires is defined, which distributes all products into 4 categories:

• non-standard (with marking in the form of the letter H);
• medium-light (letters SL);
• medium (C);
• heavy (T).

Each of these categories is represented by products with different shell thicknesses, as well as in different colors. But initially, a suitable product is selected taking into account the number of wires in the wiring and the cross-sectional area (in mm²) of each of them. The diameter of PVC pipes for electrical wiring (table below) can vary from 8 mm for corrugated pipes and 16 mm for rigid pipes, up to 20 mm and 50/65 mm, respectively.

Corrugated pipe selection table depending on the number of wires and cross-sectional dimensions:

Rigid collectors are produced by the manufacturer in sections, the length of which is on average 3 meters. Corrugated modification pipes are produced in coils, but they are sold in segments of the length required for the consumer. In total, one coil can have 25-200 meters (depending on the diameter of the model).

Rigid PVC pipe for electrical wiring has the following technical characteristics:

operating temperature mode - from -20⁰С to +60⁰С;
resistance to mechanical impulses - 2 and 6 J at an ambient temperature of + 25⁰С and -5⁰С, respectively;
dielectric properties - stability of 2000 V and more for 15 minutes;
insulation resistance - 100 Mohm or more.

For pipes with a corrugated sheath, the technical characteristics are almost the same. The dielectric properties, electrical resistance and temperature limits of this collector configuration are the same as those of a rigid pipe. But besides this, they have a characteristic of bending. So, the minimum bending radius of such products is not less than three diameters.

Features of laying wiring in insulation

From PVC pipes of a rigid and corrugated configuration, a hermetic or non-hermetic pipeline can be mounted. In order to prevent dirt and moisture from entering the network, a completely impervious design is used. A line that is laid to protect the cable from mechanical stress and shock can be leaky. Usually, a PVC pipe is used for laying a cable in the ground of a corrugated modification. Rigid collectors are used for power supply networks mounted in open spaces or on top of the ceilings. The structure constructed from them is water and dust resistant, and therefore can provide reliable insulation of wiring during operation.

When arranging power supply networks, it is important to pay attention to several key points. First of all, it is not recommended to heat pipes and wires hidden in them from heating collectors located near them. To avoid this, insulated wires and cables must be laid below the level of the heating duct. With parallel laying, the distance between the heating lines and wires must be at least 10 cm. If it is planned to cross the power supply and heating systems, the gap between them should be 5 cm.

Only a single piece of wire should be inserted into the pipe. If it becomes necessary to make a connection of wires on the line, you must additionally install a box in which the twist will be displayed. This will greatly simplify the maintenance of electrical networks due to easy access to wiring.

In rooms with normal air humidity, the installation of power supply networks is carried out in the usual way. If the humidity indicators in the room go off scale, for additional protection of the wiring, seals are installed at the junctions of the products.

Corrugated PVC pipes are more often used for installation of concealed wiring. To fix the collectors with the cable inside on a brick wall or in the floor, you need to use special metal brackets. First, you should carefully fix the lines of the power supply line, after which you can apply plaster or fill the floors with concrete, cement mortar. In places where a transition or pipe exit is planned, connectors of the same modification (i.e. corrugated) must be used.

When laying the wiring, it is important to prevent creases in the wire so that there are no problems with the broach in the future. In the event that two points are connected along a straight section, it is advisable to use solid fragments of collectors. To simplify the introduction of wires into the pipe, you can use either the probe that comes with the kit, or an elastic broach made of nylon or metal.

The use of PVC pipes significantly reduces the cost of implementing projects for laying engineering power supply systems. They perfectly cope with the role of insulation for cables and wires, which is facilitated by their technical characteristics. Considering that PVC pipes provide reliable protection of wiring from all kinds of external influences (mechanical friction, shock, pressure), any engineering complex built with their help will work without failures for many years.

For the safe laying of power and low-current electrical networks, flexible PVC pipes are used. A corrugated pipe for a cable is its protective casing, which, at the same time, is considered an ideal dielectric that protects structures and a person from electric current in case of cable damage and breakdown or fire in case of a short circuit. The peculiarity of corrugated pipes is that they have incredible flexibility, which makes their installation simple and convenient. At the same time, labor costs are significantly reduced and the possibilities of laying cable networks are expanded.

Varieties of corrugated pipes for electrical networks

Corrugated pipes are widely used by professionals and home craftsmen for laying electrical and telephone wires, television, as well as computer and power cables. Corrugated pipes are produced:

• from PVC (or polyvinyl chloride) - self-extinguishing plastic compound;
• from HDPE (or low-pressure polyethylene), having a high rate of flexibility;
• from LDPE (or high-density polyethylene), as a rule, for concealed installation in structures made of non-combustible materials or as an external corrugation for the manufacture of two-layer pipes;
• from PP (or polypropylene), for conductive channels in monolithic construction;
• made of PA (or polyamide), with a high degree of protection against the ingress of water.

Polymer pipes with corrugated profile are intended for both hidden and open laying of wires and cables. By design, they are:

• single-layer, where the outer and inner surfaces have a common wall;
• two-layer, when there is a corrugation on the outside, and a flexible, smooth surface is located inside.

Corrugated PVC pipes differ according to the version.

• Lightweight corrugated pipes are laid inside buildings, they have the greatest flexibility, have thin walls and are able to fit compactly on any bends, repeating their contour. They are often used for installing cables under wall and ceiling sheathing.
• Heavy (or reinforced) corrugated pipes are much stronger, their walls are thicker, and they are laid in a concrete-cement screed, concrete floor base, underground and outdoors.

For the convenience of pulling wires through electrical corrugated pipes, they are equipped with metal probes in the form of a steel cable, which is connected to the cable and pulls it out from the back. In this case, the installation of the electrical network is much faster. But manufacturers produce corrugated pipes without broaches. They do not differ in quality, but their price is somewhat lower.

Corrugated pipes for electrical networks are produced with diameters of 16-63mm. Manufacturers supply them with a length of 15-20-25 meters, as well as 50 and 100 meters, as a rule, in coils packed in sealed bags of shrinkable polyethylene film. Rigid corrugated pipes are sold in lengths of 2 or 3 meters.

In addition to plastic pipes, corrugated stainless steel pipes are produced by the industry, but their cost is much higher, so they are used much less often for laying cables.

Advantages and characteristics of corrugated pipes

Regardless of the version, corrugated flexible pipes made of self-extinguishing PVC:

• durable (service life exceeds 50 years) and do not lose their properties over time;
• moisture resistant;
• low flammable;
• resistant to shock and compression, rotting and corrosion;
• provide reliable protection of cables in a wide temperature range (from -20 to +55 degrees);
• environmentally friendly and safe;
• they are light in weight, therefore they are problem-free during transportation and storage;
• chemically resistant;
• make it possible to quickly replace a cable that has become unusable;
• universal;
• easy to install.

The dielectric strength of corrugated PVC pipes reaches up to 2000V with an insulation resistance of 100 ohms.

Selection of PVC corrugated pipes for cable

In plastic pipes, cables for various purposes can be laid, ranging from low-voltage networks to power ones. The size of the protective electrical casing is selected depending on the diameter of the electrical wire, the number of cables to be pulled and their purpose.

If it is necessary to supply electricity to lighting fixtures, a corrugated pipe with a diameter of 16 mm will be enough. To power switches and sockets, it is better to use a casing with a diameter of 20 mm, and if several wires are located inside the pipe, corrugated pipes with a size of 40-63 mm should be chosen. For any of the options there is a corrugated PVC pipe, the price and quality of which will be acceptable even for the most demanding customer.

A corrugated pipe should be chosen with a metal probe, which is a rigid steel wire that provides trouble-free cable pulling through a plastic casing. The monetary savings when buying a pipe without a probe will turn out to be insignificant, and labor costs will decrease significantly.

Any home master can lay corrugated pipes on his own. But one should take into account the factor that not everyone understands the intricacies of connecting electrical wiring. For this, it is better to invite a specialist.

Corrugated pipes are laid in strobes, when installing suspended or sheathing systems, as well as in an open way, performed mainly in house systems.

Corrugated PVC pipes for cables can be laid inside or outside any building structures, as they are fireproof. But if it is possible to install them inside non-combustible or slow-burning materials, then it is better to choose a safer option. You should also avoid the open method of laying in places of direct exposure to ultraviolet rays.

Mount the electrical network in the casing as follows:

• first, a corrugated pipe for the cable is laid in an open or closed way;
• the end of the electrical wire is twisted with a steel broach (probe);
• gently pull the cable from the other side of the corrugated pipe, which, if necessary, is cut with any available cutting tools (knife, scissors, saw).

With hidden laying, corrugated pipes are fastened in the body of the main building structure with cement mortar, and with open laying, they are mounted to the base with special clamps.

Metal products are gradually giving way to pipes made of polymers. Large steel structures are being replaced by lightweight PVC corrugated pipes. Plastic pipes have become popular in construction and in everyday life due to their reasonable price and fairly high technical characteristics.

Properties of corrugated plastic pipes

Corrugated PVC pipes have properties that allow them to be used in various repair and installation work. Also, corrugated PVC pipe is used when laying communication lines and electrical networks of different voltages.

PVC products can be mounted without the use of special equipment, as they have excellent flexibility. The considered type of pipes is manufactured in accordance with all established norms and quality standards.

The following advantages of corrugated PVC pipes can be distinguished:

• Incombustibility. PVC will never ignite.
• High level of isolation. In a corrugated pipe for laying a cable, the appearance of stray currents and pickups is impossible. This allows you to lay several cables in one pipe.
• Installation can be done in several ways. The connection of plastic pipes can be carried out using special adhesive solutions or by welding, which is performed by a device specially designed for this.
• Security. Polyvinyl chloride does not cause allergies and is generally a safe material for humans.
• Light weight. When installing a system of corrugated plastic pipes, there is no need to mount an additional supporting structure from fittings.
• do not rust. PVC pipes can be used in places with high humidity, as they are not susceptible to rust and aggressive chemicals.

Despite the large number of advantages, PVC corrugated pipe has limitations in use: it cannot be used for cable laying if the base is flammable. For example, if electrical wiring is installed on a wooden base. In this case, metal channels are used to protect the wires.

You can install a corrugated PVC pipe for cable in an open way or closed, that is, inside the ceilings of the building, under the finishing material (for example, decorative panels or drywall). It is also allowed to lay in a cement screed.

Types of PVC pipes

Basically, corrugated PVC pipes are made for sewerage and laying electrical wires.

Such pipes according to the degree of strength are divided into the following types:

• lungs (abbreviated as "L");
• heavy (marking - "T");
• superheavy.

Lightweight corrugated cable conduit is very flexible, which allows you to easily mount complex systems. Such pipes are used only within the premises, as under the influence of sunlight their service life is reduced.

Corrugated polypropylene pipes intended for electrical wiring are also produced with a probe (cable), which is made of durable wire. The probe allows you to install pipes faster. First, the pipes with the probe must be connected in accordance with the approved scheme, then the ends of the electrical cable and cable are connected. Next, from the other end of the pipe, you need to pull the probe. Thus, the cable will get inside the corrugation of the PVC pipe.

Regardless of which corrugated PVC pipe is chosen, with or without a probe, attention should be paid to its diameter, which should ensure the free location of the cable inside the corrugation.

It is necessary to select the dimensions of the corrugated pipe in accordance with the following recommendations:

• If you need a PVC pipe to connect the wire to the lighting fixtures inside the building, then its diameter should be 16 mm.
• For laying the cable to sockets and switches, a pipe with a cross section of 20 mm is required.
• When laying the cable in the walls of buildings and in the spans between floors, a corrugation with a diameter of at least 40 mm should be used.

Corrugated PVC pipes for drainage

A light corrugated cable pipe cannot be used for the construction of drainage systems. For drainage, there are single-layer and double-layer corrugated polypropylene pipes. Double-walled have a smooth inner surface (read: ""). Such pipes have the highest ring stiffness, due to this, the drainage system is strong and safe.

In accordance with the structure and rigidity of the material, two-layer pipes are divided into several classes. Symbol - SN2, SN4, SN6, SN8, SN16. Marking SN2 indicates that the drainage pipe has the lowest strength, and the most durable pipes are designated SN16.

Depending on the depth of laying the system, a choice is made in favor of one or another class of pipe stiffness:

• Single-wall corrugated pipes belonging to the SN2 stiffness class can be laid in the ground no deeper than 2 m.
• The maximum laying depth of pipes with a single-layer structure of grade SN4 is 3 m.
• Two-layer corrugated PVC pipe brand SN6 is allowed to be laid in the ground to a depth of no more than 4 m.
• Pipes with high rigidity and belonging to classes SN8 and SN16 can be used at sufficiently large depths up to 10 m.

Drainage pipes with an additional filter shell are also produced. Geofabric or coconut fiber acts as a filter. This structure of the drainage pipe avoids clogging with particles of earth, grains of sand, clay or silt. Pipes belonging to the class SN8 and SN16 are not equipped with filter shells.

Pipes of increased rigidity can also be used when organizing drainage at shallow depths. This will increase the life of the drainage system.

In addition to corrugated pipes, such a system includes fittings and wells. Wells are made in those places where the elements of the system are connected when the direction of the pipeline changes. Wells provide free access to the joints of drainage corrugated pipes for their repair or cleaning.

Comparison of PVC and HDPE corrugated pipes

What is better to choose corrugated pipes made of PVC or low pressure polyethylene (HDPE)? In this case, it is necessary to be guided by the purpose of their use.

These types of polymers have different characteristics and can be used for different purposes. These materials have a long service life. If you do not violate the rules for their use, then the service life can reach 50 years. Pipes made from such materials can be used to transport aggressive chemicals.

Pipes made from HDPE are best suited for:

• protection of low-voltage networks;
• conducting open networks on the street;
• cable laying in the ground;
• pressure and non-pressure sewerage devices;
• organization of drainage.

When pulling high-voltage cables, only smooth-walled HDPE pipes with a rigid structure can be used (more details: ""). When laying electrical cables inside and outside residential buildings and industrial buildings, only corrugated PVC pipes are allowed.

PVC refers to self-extinguishing materials, that is, after the cessation of exposure to open fire, combustion immediately stops. HDPE has a low degree of flame resistance, and they do not contribute to its spread, however, spot fires can occur in these systems.

Due to its technical characteristics, this material is able to withstand low temperatures, so it can be laid in difficult weather conditions. Polyvinyl chloride loses its qualities already at -10°C, and polyethylene can remain unchanged even at -60°C.

The price for HDPE is lower than for PVC, however, additional cash costs will have to be incurred during their installation. PVC pipes are connected by butt welding or by means of electromagnetic couplings. In this case, a better result will be obtained.

Due to their light weight and many other technical characteristics, PVC pipes are one of the best solutions for laying systems for various purposes. Installation work is not accompanied by difficulties, but you need to know what features a PVC pipe has. Additional features of this product include:

• long service life;
• affordable cost;
• light weight;
• ease of installation.

The small weight allows installation without the use of special fasteners. In addition, you will not need an expensive tool, you can lay the pipeline yourself, while saving your money. As one of the significant advantages, the absence of disadvantages that are characteristic of cast iron and metal pipes should be highlighted.

That is why these pipes are increasingly used in many areas of human activity, displacing products from other materials. After all, they are more durable, do not provide for complex and expensive maintenance, and they can be laid at minimal cost.

Specifications

PVC pipes have outstanding performance features. They are characterized by high ring rigidity, due to which the products are able to withstand internal pressure up to 120 atmospheres. The pipes are extremely resistant to temperature deformations. When heated, the pipe lengthens by only 5% of its original volume. As for frost resistance, PVC is not so resistant to such influences. Therefore, this material must be accompanied by thermal insulation.

The pipe must not be cooled below -15 °C. PVC pipes are not so good heat resistance. The material begins to lose its stiffness when exposed to temperatures above 78 °C. External and internal surfaces have minimal roughness, which prevents silting of the pipeline. Structural material can have quite impressive light transmission. You can meet a transparent PVC pipe on sale, however, in most cases, the products are supplied in a painted form. But even in this state, polyvinyl chloride is able to resist ultraviolet radiation better than other types of plastic.

Water during transportation through PVC pipes does not change its properties. This indicates that communications of this type can be used for pumping not only technical, but also drinking water. Among the main advantages of such pipes are inertness to the transported medium and high ring stiffness, which makes it possible to lay high-pressure pipelines.

As for hot water supply systems, PVC cannot be used in them, since the temperature limit for the operation of the pipeline is only 40 ° C. While other advantages are required from pipes in non-pressure systems, among them are the minimum wall thickness and the high smoothness of the inner surface. As for the thickness, it can vary from 1.5 to 6 mm. These properties make it possible to lay a sewer system of impressive length. As a result, it is possible to obtain systems with a small cross-section of the pipeline, which are capable of diverting a significant amount of wastewater.

Some characteristics of non-pressure PVC pipes

Non-pressure PVC pipes can be laid and interconnected using sealing rings. This method of installation is acceptable for external and internal systems. Non-pressure pipes have a thickened socket at one end, the diameter of which can vary from 63 to 315 mm. Such pipelines can be operated at a maximum working pressure of 0.63 MPa. However, the pipe itself is capable of enduring up to 20 MPa.

Characteristics of PVC

Polyvinylchloride PVC pipes can also be pressure. They have the ability to withstand impressive pressure, so cool products are used to assemble pipelines. They look like bell-shaped ones, but at their end there is a special thickening in the form of a bell.

The diameter of a pressure-type PVC pipe can vary from 10 to 90 mm. In accordance with GOST, 11 original standard sizes can be counted. The maximum working pressure is 2 MPa. If this value is exceeded, then the adhesive line will not cope with the load. On sale you can also find a pipe without a socket, it is used when assembling the system of the following types of fittings:

• sealing;
• threaded;
• adhesive.

The diameter of smooth pipes varies from 10 to 315 mm. Such products can be used not only in pressure, but also in non-pressure systems.

Corrugated PVC pipes: properties

Corrugated PVC pipe has the ability to self-extinguishing, this is a priority, which is one of the most important when laying electrical wiring. The pipe does not burn, but melts and smolders, completely attenuates and stops the fire. Such pipes are durable, they have a crack-resistant water-repellent surface that does not corrode, does not lose its properties and does not dry out during the entire service life.

Pipes electrical corrugated polyvinyl chloride thermoplastic. They respond minimally to temperature changes. operation can vary from -20 to +80 °C. As for installation, it must be carried out at a temperature of -5 to +60 °C. Among other things, polyvinyl chloride acts as a dielectric, which indicates its insulating ability.

Mounting Features

The pressure pipeline starts from the source and ends with a valve. The non-pressure pipeline at the beginning has a PVC-type siphon, while at the end there is a septic tank buried in the ground. To connect the septic tank and the siphon, it is necessary to equip a winding line, which will include fittings and pipes. The installation process can be carried out according to one of three technologies. The first involves the use of a socket, the second - cold welding, while the third - threaded fittings.

Features of the installation of PVC sewer pipes

PVC sewer pipe is laid according to a certain technology. At the first stage, the elements must be adjusted to each other and check whether the slopes and angles match. Next, markup is carried out so as not to get confused in a large number of components. The elements are interconnected, it is important at this stage to check that the pipe enters the socket by 2/3 without effort.

For tightness, the joints are glued with a special compound. In order to increase adhesion, mating points should be roughened. Once the adhesive has been applied, the fitting can be put on. After completing the installation work, you need to check the system for leaks. If the leak is not detected, then the installation work was carried out successfully.

Bell assembly

Polyvinyl chloride pipes (GOST 51613-2000) can be assembled into a socket. Tee fittings are required for a T-piece from one branch to another. A sealing ring should be placed in the socket, and the smooth end of the pipe should be installed in the sealing socket. The ring will hold the smooth part and seal the joint.

Assembly using cold welding

Cold welding installation can be practiced when laying the pipeline, when it is necessary to provide a corner connection or tie-in. If in the latter case it is used, then in the first one you can get by with adhesive fittings and smooth pipes.

Assembly using glue is as follows. At the first stage, it is necessary to cut the end and calibrate, that is, clean and deburr. The master should check the immersion depth of the smooth end, followed by marking.

After that, the outer surface of the smooth end is treated with a solvent, and the joint is cleaned. With the inner surface of the fitting and socket, it is necessary to carry out a similar action. Once cleaning has been carried out, a special adhesive must be applied to the surface of the fitting and pipe, which should cover the inner surface and the marked area. At the final stage, the pipe must be pressed into the socket or fitting to the depth marker, and then rotated around the axis, this will allow the adhesive to be evenly distributed.
