Abstract
A pipeline for the transport of a pressurized flowable medium, consisting of a metal tube corrugated transversely to its longitudinal direction and of a hose which is arranged in the same and consists of plastic. In the position of use the hose bears against the inwardly pointing wave troughs of the metal tube, which hose has a multiplicity of holes separated from one another in the wall of the same over its entire axial length. The wave troughs of the metal tube penetrate slightly into the surface of the hose so as to fix the latter with respect to axial loads.
