Plastic pipe with profiled layer and method for manufacturing the same
The invention relates to a plastic pipe (1) comprising at least a profiled layer (2) with circumferentially extending profiles (3), such as corrugations or ribs. The profiled layer (2) is provided with at least one reinforcement band (10), extending in a generally longitudinal direction of the pipe, thereby following the contour of successive profiles (3). The reinforcement band (10) may be rib shaped and may be made of the same material as the layer. Preferably, the reinforcement band at least partly overlaps with a split line in the profiled layer, produced between adjoining die blocks during formation of the profiles. The invention furthermore relates to a method of manufacturing a pipe according to the invention.
