Abstract

A double walled pipe assembly comprises an inner component pipe (304) and an outer component pipe(306) and an annular insulating space (314) between them. The ends of the pipes are joined by circumferential welds to close the annular space. At least one of said component pipes is provided at at least one of its ends with a thickened portion, the annular space at said portion being reduced substantially to zero. The outer pipe is welded in said portion to the inner pipe by a circumferential lap weld (508). This construction accommodates a relatively wide tolerance in length and parallelism between the inner and outer pipe ends prior to welding. The thickened portion may be provided by deformation of the material of the pipe section, or on a separately fabricated end-piece butt welded to a plain- ended section of the inner or outer pipe section.
