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 and Spiral HWDP.
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.
