To date, many devices have been created to ensure reliability and protection against fire in a home, including PVC metal hoses. Their presence will allow you not to worry about safety in the event of a short circuit of various cables and electrical wiring from mechanical damage.
=2744" title="Metal hose"> Metal hose PVC - flexible conduit made of galvanized steel tape and a layer of PVC insulation ... The PVC metal hose has some features. If we compare it with a conventional metal hose, the PVC version is characterized by a number of advantages: impermeability to water, corrosion, radio interference, electromagnetic fields, mechanical damage, the influence of the environment in general; great strength and durability; ability to withstand high and low air temperatures. Installation has its own specifics, therefore it is worth entrusting this issue to a specialist.
The choice of a metal hose should begin with calculating the length, taking into account the design of the products to be joined. It cannot be made too short or long, since this will lead after some time to breakage at the attachment point, its actual dimensions should not differ from the calculated ones by more than 3 percent. Areas that are located directly next to the reinforcement must be placed without bends. When calculating and installing, it is worth considering that the work of the metal hose in tension, compression and twisting is prohibited. For example, there are standards that prohibit bending to a radius less than 5Du (if the pressure is up to 10MPa); less than 10 DN (in case of critical products); less than 12 DN (at a pressure of more than 10 MPa).
