To ensure the safety and tightness of electrical, telephone, television and other networks, corrugated stainless steel flexible pipes are used, as well as for hidden electrical wiring in a wooden house.
Corrugated pipes for electric cables are made of polished stainless steel AISI 430 with a thickness of 0.3 mm, which makes up their outer and outer layers.
The cable protection pipes are manufactured using argon-arc Tig welding, due to this welding the corrugated pipes are completely sealed.
Reliable protection of electrical, telephone and television wires is provided by a flexible corrugated pipe, which just as well protects the cable laid in a concrete wall, floor, ceiling in the ground and in a wooden house.

Damage to the cable insulation can lead to irreversible consequences if you do not use a protective corrugated stainless steel pipe, which reliably protects the wires and does not corrode.
In some flexible corrugated pipes, a metal wire broach is provided, which greatly simplifies the process of installation and cable laying.
In this case, it is enough only to lay a flexible stainless steel pipeline, install a cable, one end of which is connected to a metal wire. After that, the cable is simply pulled out by the broach from one end of the corrugated pipe. In this case, the use of corrugated pipes is very convenient and significantly reduces the installation time.

The laying of electrical cables and network wires under the ground involves the use of a special pipe. The widely demanded corrugated pipe for the cable into the ground guarantees reliable protection against damage, and also prevents the spread of fire in the event of a short circuit in the network. The localization ability of a stainless corrugated pipe is the property of a non-combustible material in which a wire or cable is laid to withstand short-circuit currents in an electrical circuit without burning the walls of the non-combustible material.
Laying the corrugated pipe is quite easy and convenient, so the underground installation of the electrical cable will not take much time.
High-quality stainless corrugated pipe for hidden cable laying in a wooden house, a hollow corrugated tube that can bend due to a ring corrugation, protects the cables from breaks and prevents them from getting wet. Corrugated stainless steel tube protects the electrical cable from gnawing mice and other rodents.
Corrugated stainless steel pipe, due to its own flexibility, does not require the use of special turns and connectors, so this option is considered a budget option.
The price of a corrugated pipe is not more expensive than other types of pipes for cable laying
The company "Komtsentr Strategy" produces corrugated stainless steel pipes with a diameter of 12 mm, 15 mm, 18 mm, 20 mm with a wall thickness of 0.3 mm for the installation of hidden electrical wiring in a wooden house.
The price of a corrugated pipe made of stainless steel of the AISI-430 brand ranges from 45 to 60 rubles per meter.
It is also possible to protect the outer layer of the stainless corrugated pipe with a polyethylene coating - high pressure polyethylene, which provides the pipe with an absolute external smoothness.
Thanks to this coating, the corrugated pipe becomes more durable and does not fray during mechanical stress and has a higher corrosion resistance.
