Abstract
The present invention may be used for protecting main ducts against corrosion and for increasing their pressure-bearing capacity. The method of the present invention comprises applying a polymeric material to the inner surface of the duct by bringing said material to a viscous flow state and by curing the same. The polymeric material is brought to a viscous flow state in an independent thermo-mechanical module and is applied by extrusion. The thermo-mechanical module is displaced inside and along the duct, wherein the displacement and power supply of said thermo-mechanical module are ensured by the kinetic energy of a gaseous agent, such as natural gas or air, which is transported along the duct by generating a pressure therein.

Regulating the speed of movement of the module is effected by a change in the pressure drop in the pipe in the range 0.05 -7.5 ° C, so that the speed of the room is prevented up to 1 m / min. Ме On the other hand, the material used is polietilen. The heating of the material at the time of processing the plant is 220-250 ° С. The module provides power to the engine, which drives the engine and supplies power to the power supply. The finished polymer material is thermally converted into a viscous state and extruded by the material onto the pipe wall. The module is not connected to external devices. The supply of waste products to the module is carried out due to the energy of the gas supply in the pipe. To improve the adhesion of the primary spray to the wall, the pipe at a predetermined length at a predetermined length may be less sensitive to the use of fluids.
