Corrugated pipe with stress relief and a method for its manufacture from plastic |
摘要 |
The corrugated pipe has at least one longitudinal rib on the wall. This longitudinal rib connects the corrugation rings to one another and hence prevents length changes of the pipe in the direction of the pipe axis. The bending capability of the pipe is nevertheless maintained.
