FIELD: construction.
SUBSTANCE: invention is related to the field of pipes from plastic masses. In method of combined pipe manufacturing, including arrangement of sealing thermoplastic layer on technological mandrel, winding of fibrous material with binder and polymerisation, sealing layer is arranged by winding of extruded thermoplastic tape onto mandrel with overlap and simultaneous heating of joint of the latter in process of winding, then layer of woven cellular fibrous material is wound with partial penetration into uncooled sealing layer, and fibrous material with binder is laid over this layer with further polymerisation.
EFFECT: improved reliability.
