PLASTIC PIPE, PIPING COMPRISING A PIPE AND A METHOD FOR PRODUCING A PIPE

摘要

The invention relates to a pipe comprising smooth cylindrical sections (3), in addition to sections (4) that are externally corrugated and internally smooth. Each of the smooth cylindrical sections (3) has retaining elements (2), which are located at a distance from one another on its exterior, in the longitudinal direction of the pipe and are preferably configured as circular ribs. The pipe (1) is shortened to produce a plug-in connection in such a way that a smooth cylindrical section (3`) forms a free end and a connecting piece (13) can be snapped onto a retaining element (2a`). The externally corrugated sections (4) are flexible.
