Abstract

Disclosed is a double walled pipeline assembly, an associated set of parts and a pipeline installation and a method for forming and installing the same. The double walled pipeline assembly consists of an inner pipe section (304) and an outer pipe section (306) having an internal diameter larger than the external diameter of the inner pipe, enabling the inner pipe to be located coaxially within the outer pipe to leave an insulating gap (314) between them. The outer pipe has a shorter length than the inner pipe and is also tapered inwardly by swaging at both ends, forming a part-conical shape (318b) and a straight cylindrical form (318a) that approaches and lies parallel to the surface of the inner pipe to enable welding. By doing this a low cost and weight field joint between pipe-in-pipe sections can be obtained.
