摘要

The invention concerns a method of manufacturing a pipe section (1), at least a part of the outer surface of which is ribbed, by extruding plastic or another thermoplastic material and a pipe section (1) manufactured in this manner as well as a joint between two pipe sections. To provide a thin-walled pipe section (1) the material is extruded into a mould by using as extrusion point the mould point corresponding to a rib (15) situated in the middle area of the pipe section (1).
