Abstract
A method of preparing a pipe-section for welding to another pipe-section to form a pipeline comprising a plurality of said pipe-sections, the method comprising at least the steps of: (i) providing a pipe-section having first and second pipe-ends; (ii) defining a first portion Lof the longitudinal length of the pipe-section from the first pipe-end being in the range 3% to 40% of the overall length of the pipe-section; (iii) defining a second portion Lof the longitudinal length of the pipe-section from the end of the first portion Ltowards the second pipe-end; (iv) heating at least the first portion Lto at least a first temperature Tof at least 500° C. for at least 2 minutes; (v) maintaining a second temperature Tof the second portion Lduring step (iv) below the first temperature T. The invention is able to reduce the strain capacity during reel-laying of a pipeline formed from a plurality of pipe sections formed by the invention.
