FIELD: machine building.
SUBSTANCE: invention relates to pipe moulding devices. The device contains molding units made to move along the moulding channel to produce a plastic pipe. The pipe has a corrugated outer wall, the corrugation setting the pipe outer diameter and an inner wall around the channel passing all along the pipe length. The moulding unit sections feature profiled surfaces defining the pipe shape. Note here that the profiled surface shape can be varied for both the corrugation depth and the diameter of the channel all along the pipe length, the pipe outer diameter undergoing no changes. The device incorporates extra cooling inserts to mould pipes.
EFFECT: varying the pipe shape without changing the moulding units.
