Over the past decade BP and Sumitomo have been developing and promoting the use of X100 grade steel pipe for large diameter high pressure onshore gas pipelines. In 2006, Sumitomo supplied 0.5km of X100 linepipe to BP’s X100 Operational Trial. The X100 Operational Trial is a 48-inch, 180barg X100 pipeline situated in Northumbria, UK, built specifically to advance industry acceptance of the use of X100 in onshore gas pipelines and to demonstrate the long term operational performance of the material under normal and adverse conditions and at higher design factors. In this paper the mechanical properties of the X100 pipes supplied are summarised and background to the linepipe specification and manufacturing process provided. In addition, the effect of specimen type and external coating on mechanical properties is also discussed.
