FIELD: mechanical engineering. SUBSTANCE: lining hose impregnated with polymer binder is placed in the pipe line and is pressed to its inner surface. Binder is structurized at hardening by heating it with steam fed to the pipe line under pressure. Hardening is effected in two stages using the heat liberated at steam condensation. To this end, condensation is maintained continuous. First-stage heating is continued till linear structure of binder is obtained. Structuring is terminated at second stage. At first stage, pressure of steam is maintained at 0.1 to 0.3 atm for 10 to 20 minutes and at second stage, pressure of steam is maintained within 0.5 to 0.7 atm for 2.5 to 5 hours. EFFECT: enhanced reliability. 1 tbl
