Method and device for producing a pipe

An apparatus for producing a pipe including walls between ends of which have at least one channel that passes through said wall, comprising:

• a blow-moulding tool in which a tube blank composed of plastic is blow moulded, wherein the blow-moulding tool has a convexity for each of the at least one channels, wherein the convexity is lined by the tube blank and has internal measurements greater that are than exterior measurements of each of the at least one channels,
• a crush-moulding tool with which the tube blank in a not-yet-solidified state is configured for being crushed in a region of the convexity such that for each of the at least one channels a rough channel results that communicates with an interior of the pipe, wherein the rough channel is closed on an end distant from the pipe interior and has the exterior measurement of the at least one channels included with the exception of a desired channel length, and
• a cutting tool with which the crushed tube blank in a solidified state is cut in a region of each rough channel such that subsequent thereto, the individual at least one channels are open and have the desired channel length.

A pipe with a wall that, between ends of the pipe, has at least one channel that passes through the wall, wherein the pipe is composed of plastic and is crushed and cut in a region of the of the at least one channel included.
