GIS/P2: Specification for Welding of Steel Land Pipelines Designed To Operate At Pressures Greater Than 7 Bar (Supplementary to BS 4515-1:2009)

This specification provides requirements for the welding of steel land pipelines, designed to carry non sour dry natural gas and to operate at pressures greater than 7 bar; in accordance with IGEM/TD/1 in the UK, or IS 328 in the Republic of Ireland. This specification details the requirements for the welding of carbon, carbon manganese and low alloy steel pipelines with specified minimum yield strengths (SMYS) not exceeding 555 N/mm2 (i.e., grade L555 or X80).
