• Commercial Sour Service Grade Drill Pipe



    Description

    XD™ is designed for the most severe H2S environments. Our XD grades feature restricted yield tool joints and a NACE TM0177 Method A-tested tube for optimum fracture toughness, controlled yield strength and restricted hardness. It is available in XD 95 and XD 105 with respective 95 and 105 ksi tube SMYS.

    TSS™ is a variation of our XD product, featuring a NACE-tested tube and API tool joints with a SMYS of 120 ksi. It is typically used in drilling applications where connection strength is required and H2S embrittlement is well mitigated. We offer TSS 95 and TSS 105 with respective 95 and 105 ksi tube SMYS.
