Beschreibung
Zusammenfassung:	The inventive method for protecting from corrosion and scale deposit and restoring tubes of heat-exchanging equipment consists in applying a polymeric coating on the internal surface of tubes by gradually and rotationally moving an excessive volume of polymeric material therealong and in hardening said material. A polymeric compound having an at-rest viscosity ranging from 1000 to 1200 poises and a thixotropic viscosity reduction during the displacement thereof is used as a polymeric material. The inventive device for carrying out said method comprises a loading chamber (2), a connecting washer (12), a unit for progressively displacing the polymeric material provided with spaced rigid washers (4,5,6) fixed to a metallic rod (7), an elastic screw (8) having a conical shape whereby the conicity thereof ranges from 5 to 10 DEG on the side which is opposite in relation to the connecting washer. Said elastic screw is arranged in such a way that it is enable to perform the gradual rotation, the rotation displacement being performed at a linear speed of 0,4-1,0 m/sec and the gradual displacement being performed at a speed of 1-0,49 m/sec.
