Europipe’s experience and developments on pipe material for sour service applications

This paper gives an update on Europipe’s activities for developing and delivering sour gas resistant pipes. Europipe’s experience to provide material for sour service stretches back more than 30 years, combining market requirements with technical feasibilities for steel, plate and pipe production. The use of high strength pipes is an important measure to decrease pipeline costs. For most severe sour conditions, grades were limited to X65 due to technical reasons. Less severe sour gas conditions enable the use of higher strength grades but recent developments showed that solutions are also available for X70 and X80 under most severe sour gas conditions.
