DP-Master’s sour service grade drill pipes are designed for use in H2S environments providing excellent resistance to sulphide stress cracking compared to standard grade drill pipes. Our sour service grades are suitable for a wide range of sour service environments from mild to severe sour environments.

With offshore drilling operations being executed in ever-deeper water and extended reach wells, DP-Master’s high strength grades were developed to overcome the demands of the most challenging and complex drilling environments.
