Abstract

The plastics pipe comprises a smooth inner wall (10) surrounded by a corrugated outer wall (11). The two walls are joined to each other at valleys (12). The wall parts (14,17) extending transversely to the pipe axial direction form at least one inward shoulder (15) between a valley and top.
