Abstract

A pipe for use as part of a subsea pipeline has two end sections (a) separated by a central section (1),the latter section having a wall thickness (s) greater than the wall thickness (s1) of the former sections. The length (L) of the pipe is from 0.5 to 10 times its nominal external diameter, and the length (a) of each end section is at least 1.5 times the wall thickness (s) of the central section. The pipe, when used as part of a pipeline, reduces the tendency for fractures to be propagated along the pipeline. <IMAGE>
