Method for the production of thermoplastic pipes |
摘要 |
A method of manufacturing a pipe (1) from thermoplastic material consists in helical winding of an element from thermoplastic material onto a drum (5) with the use of rotary rollers (4) and bonding together the adjacent coils. In particular, the pipe (1) is manufactured from a pre-manufactured strip (2) from thermoplastic material by helical winding of the strip (2) onto the drum (5) and the adjacent coils are bonded together, wherein a helical rib (6) in the form of a pre-manufactured strip (3) from thermoplastic material, is attached to the external surface of the manufactured pipe (1), wherein said rib (6) is attached to the pipe (1) by one of the side edges of the strip (3) in such a way that the side surface of the strip (3) is perpendicular to the external surface of the pipe (1). |
