FIELD: construction engineering; applicable in application of insulating coatings to steel pipe surface. SUBSTANCE: bath filled with heated bitumen-polymer mastic is located in hollow of trestle. Installed parallel to bars of trestle are rails, installed on which is telpher car with spool carrying roll of reinforcing fiber glass mat. Bath has hydraulic cylinders for its lifting. Installed on pipe ends are rings-diaphragms, and pipe is laid on bars. Bath with heated mastic is lifted by hydraulic cylinders and pipe rests on drive rollers, turns round its longitudinal axis and its external surface is coated with bitumen-polymer mastic. Edge of reinforcing material is secured to pipe surface and wound with tensioning on pipe external surface with longitudinal motion of car along rails. EFFECT: extended assortment of engineering means, reduced consumption of coating materials. 3 cl, 2 dwg
