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 L1 of 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 L2 of the longitudinal length of the pipe-section from the end of the first portion L1 towards the second pipe-end; (iv) heating at least the first portion L1 to at least a first temperature T1 of at least 500° C. for at least 2 minutes; (v) maintaining a second temperature T2 of the second portion L2 during step (iv) below the first temperature T1. 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.

Abstract: A tubular assembly (10) for conveying corrosive fluid including a first iron-based tubular (12) having a cladded inner surface (14); and a second iron-based tubular (16) having a cladded inner surface (18). The first tubular (12) is connected to the second tubular (16) using a non-iron based bonding material (20). The tubular assembly (10) includes a first cladding (22) including a corrosion resistant material along the inner surface (14) of the first iron-based tubular (12) and a second cladding (24) including a corrosion resistant material along the inner surface (14) of the first iron-based tubular (12); the second cladding (24) being adjacent the first cladding (22) and proximate an end (38) of the first iron-based tubular (12) connected to the second iron-based tubular (16) by the non-iron based bonding material (20).
