Pipes are products that are used in many areas. They are used for the transportation of various liquids, for the construction of structures, and for electrical installation activities. For example, PVC pipe for electrical wiring is a very important part of protecting the system from external damage. In addition, fire safety standards assume the use of pipes made of plastic.

Varieties of products for electrical wiring
Pipes are designed to protect cables and wires from external influences. There are various properties of these products.
Characteristics of steel pipe
The main disadvantage of such products is their susceptibility to corrosion. Even painting cannot solve this problem. In addition, some problems may arise with their installation if you do not follow a number of rules:
- all sections need to be thoroughly countersunk and cleaned;
-
all bends must be made strictly at right angles; - during bending, care must be taken to ensure that the product does not change in cross section;
- to avoid corrosion, it is better to install the installation with a slight slope towards the junction box;
- steel pipes to protect electrical wiring, being electrical conductors, acquire excessive electrical potential.
It is for these reasons that metal tubes are becoming less popular today, products from other materials prevail on the market.
Description of copper structures
Copper is characterized by a high level of resistance to corrosion processes. This material is valued for its durability and plasticity. There are no problems with the installation of copper pipes, but even these excellent performance properties do not allow maintaining the wide popularity of copper, because in terms of the mass of indicators it is inferior to analogs from plastic.
In addition, metal pipes have other disadvantages - significant weight, high cost and the need for special devices during installation.
PVC and HDPE pipelines
Plastic tubing is a modern material that has many advantages. Consumers highlight the following positive properties:
- resistance to corrosion and chemicals;
-
durability (up to fifty years); - light weight, which greatly simplifies installation and transportation;
- resistance to moisture;
- flexibility;
- affordable price;
- ease of installation.
Pipes for PVC wiring are made of non-combustible material using a special technology. These products can be of different lengths and diameters. Smooth products provide the electric cable with additional mechanical and insulation protection.
Modern corrugated products
Shirring technology increases the stiffness of the tubing. For the production of such products, non-combustible plastic is used. These pipes are indispensable for the installation of raised floors and suspended ceiling structures: flexible sleeves allow to lay electrical cables in hard-to-reach areas, where the installation of rigid products does not seem to be possible. Corrugated pipe products have the following advantages:
- providing reliable protection;
- excellent insulating properties;
- no need to use additional fittings;
- the ability to create bends;
- protection of wiring from fire.
Corrugated tubes are often used to install telephone, computer and television networks. The diameter of the product depends on the type of connected equipment and operating conditions.
Rules for installing PVC pipes
Leaky structures are installed only to protect cables from mechanical stress. Dust- and moisture-proof pipes are used against influences of a different plan. To prevent overheating of the cables from the heating system, the wiring must be installed below the radiators. It is forbidden to connect separate wires inside structures. In such areas, you need to install special electrical boxes.
In conditions of high ambient humidity, gaskets must be inserted at the joints of the pipes. At normal humidity, this rule is not at all necessary.
To fix the product to the ceiling or wall surface, special clips made of plastic or aluminum are used. First of all, the places of the ends of the tubes are marked, and then the wiring route, all the corners and attachment points are located. Plastic pipes can be bent at 100 degrees Celsius. Metal parts present in the wiring must be neutralized and grounded with nuts or jumpers.
It is important to prevent the formation of kinks, as they greatly complicate the process of pulling the wires. To do this, you can use nylon or metal wire. One end of it is inserted into a tube, and then an electrical cable is attached to it.
The performance properties of PVC pipes are excellent for protecting electrical wiring from damage. They fully comply with all standards and regulations.
