The supplier of high-performance thermoplastics, announces that semi-finished tubes made of its KetaSpire KT-820 NT polyetheretherketone (PEEK) resin achieved NORSOK M-710 compliance for use in oil and gas applications.

ATO s.r.l., a supplier of sealing components based in Milan, Italy, manufactured the semi-finished tubes using its STABIL Hot Compression Molding process. Following the certification of KetaSpire PEEK, ATO unveiles plans to specify the high-performance polymer for additional products distributed under its STABIL label, including bearings, seals and back-up rings that target critical oil and gas equipment and installations.

NORSOK standards are an internationally recognized set of testing methodologies originally developed by the Norwegian petroleum industry. The M-710 standard specifically defines requirements for critical non-metallic (polymer) sealing, seat and back-up materials for permanent sub-sea applications.

Element Hitchin, an independent testing and analytical laboratory (formerly known as Materials Engineering Research Laboratory, or MERL) based outside of London, evaluated KetaSpire KT-820 NT PEEK according to NORSOK M-710 multi-phase sour service conditions in fluid at 10 percent hydrogen sulfide, 5 percent carbon dioxide and 85 percent methane at 10 MPa (100 Bar) and at test temperatures of 200ºC (392°F), 210ºC (410°F) and 220ºC (428°F). The exposure testing spanned 49 days and periodically measured swelling and tensile properties of the KetaSpire KT-820 NT resin samples. The tests showed Solvay’s high-performance PEEK delivered good resistance to sour gas and no measurable chemical deterioration during the test period.

KetaSpire PEEK is one of the industry’s most chemically resistant plastics and offers an exceptional combination of strength and toughness, along with superior fatigue resistance and a continuous-use temperature of 240°C (464°F). It also exhibits high purity and consistent high quality in processing and part performance. Glass fiber-reinforced and carbon fiber-reinforced grades provide a wide range of performance options for demanding applications.
