Flexible pipeline

摘要

A flexible pipeline for transporting a pressurized flowable medium, includes two pipes of metal which are corrugated transversely of their longitudinal direction, an inner pipe and an outer pipe which are arranged concentrically relative to each other with the inclusion of an annular gap. A vacuum insulation is arranged in the annular gap between the two pipes. On the other side of the inner pipe is mounted a tension proof reinforcement which is connected at both ends of the inner pipe fixedly to the inner pipe.

1. Flexible pipeline for transporting a pressurized flowable medium, comprising:
two metal pipes which are corrugated transversely of their longitudinal direction, said metal pipes including an inner pipe and an outer pipe which are arranged at a distance concentrically and relative to each other so as to form an annular gap, wherein a vacuum insulation is mounted in the annular gap between the two pipes, wherein that on the outside of the inner pipe a tension proof reinforcement is fixedly mounted at both ends of the inner pipe, and wherein said reinforcement has two tension proof strands which are wound helically in at least two layers with different pitch directions one above the other around the inner pipe.
