FIELD: power-plant engineering, in particular, construction and repair of pipe-lines, applicable at their location under ground and on the ground. SUBSTANCE: a prefacing pipe is arranged in the pipe-line by turning out by a liquid column with simultaneous pulling through in this liquid of a facing combination hose on the basis of reinforcing material with an outside coating of sealed film material impregnated by binder, an insulating pipe is introduced inside the combination hose by turning out, and the binder is cured. Pulling-through of the combination hose is accomplished by simultaneous action of liquid column and tractive force of the cable, which is preliminarily placed in the cavity of the prefacing pipe, the brought-in-line ends of this pipe and cable are connected to one of the ends of the combination hose, and the cable free end is connected to the pulling device. EFFECT: simplified process of pipe-line facing, expanded technological potentialities by provision of repair of pipes of large dimensions in length and diameter, cheapened process. 2 dwg
