Corrosion performance of welded CRA-lined pipes for flowlines

Abstract

This paper presents the results of corrosion and mechanical testing of welded high-nickel, corrosion-resistant-alloy (CRA)- lined pipes manufactured using various lining processes. The corrosion resistance of CRA-lined pipes for use as a flowline material in sour service was evaluated. The effects of the manufacturing process, CRA lining material, and welding on the corrosion performance of CRA-lined pipes also were determined
