FIELD: construction.
SUBSTANCE: method comprises setting the shell impregnated with glue in the pipeline together with the air-tight film hose through hollow cantilever, moving shells pressed to the inner surface of the pipeline by the air pressure drop, blowing the hose by heated air or steam from the steam generator until the glue is completely polymerized, and removing the hose after polymerization. The space between the inner surface of the pipeline and film hose is evacuated by means of evacuating nozzle and vacuum pump.
EFFECT: enhanced quality of coating and reduced power consumption.
