Beschreibung
Zusammenfassung:	FIELD: manufacture of main pipe lines. SUBSTANCE: method includes fitting the metal tips in winding device, laying of at least one solid sealing layer, winding reinforcement impregnated with polymer on it and hardening during heating. Prior to laying the solid sealing layer on outer surfaces of tip, duplicating sealing layers which are not in contact with each other are laid on outer surfaces of tips. Then, separating layer is applied on them at spaced relation relative to outer edges. EFFECT: enhanced reliability. 4 cl, 3 dwg
