Abstract

A method of manufacturing a pipe ( 1, 26, 26' ) from thermoplastic material consisting in helical winding of a pre-manufactured strip ( 2, 21, 21' ) from thermoplastic material onto a drum with the use of rotary rollers and bonding together the adjacent coils is disclosed. Prior to winding said strip ( 2, 21, 21 1 ) onto the drum ( 5 ), the strip ( 2, 21,21 1 ) is formed into a U-profile ( 3 ) or an L-profile ( 8 ) in cross section, and after that the so formed profile ( 3, 8 ) is wound onto the drum ( 5 ) at the same time bonding together the adjacent coils in such a way that a wall or walls of the L-or U-profile (3, 8 ) create an external, helical reinforcement rib ( 6, 25, 25' ) of the pipe ( 1, 26, 26' ). Further disclosed is a thermoplastic strip for manufacturing such a pipe.
