• Heavy Weight Sour Service Grade Drill Pipe

    Description

    eXtreme Drilling XD™-90 is a proprietary Heavy Weight Drill Pipe (HWDP) product offered by Grant Prideco for service in H2S environments. XD-90 is available in both Standard, Tri-Spiral and SPIRAL-WATE™. 

    XD-90 provides higher strength and a tempered martensite microstructure for enhanced resistance to crack initiation and crack propagation compared to conventional HWDP. XD-90 incorporates a proprietary chemistry and a rigidly controlled quench and temper heat treatment process. XD-90 has a minimum yield strength of 90,000 psi. With a NACE threshold stress of 85% of yield strength, XD-90 is resistant to sulfide stress cracking. Its high fracture toughness makes XD-90 ideal for the most demanding drilling conditions, including applications with high bending loads and corrosive environments.
