Abstract

A process for the laying of high pressure fluid pipelines is described, in which the existing fluid pipelines of different nominal pressure stages are used in order to provide a new assembled high pressure fluid pipeline of a standardized and higher nominal pressure stage. This is achieved by inserting a woven fabric hose of a correspondingly higher nominal pressure stage into the existing old fluid pipeline according to the woven fabric hose relining process.
