OCTG: Casing, Tubing & Drill Pipe: FAQs
What casing grades are suitable for sour service?
API 5CT grades L80 Type 1, C90, T95 and C110 are restricted-yield grades qualified for H2S service under NACE MR0175. Proprietary sour-service grades (e.g., 'SS' grades from mills) are also available.
What is the difference between API and premium connections?
API connections (STC, LTC, BTC, EUE, NUE) rely on thread compound for sealing. Premium connections add a metal-to-metal seal and torque shoulder for gas-tight performance, higher torque and better resistance to combined loads, qualified to API RP 5C5 / ISO 13679.
Can you supply 13Cr and CRA tubing?
Yes. We supply L80-13Cr, super 13Cr, duplex 22Cr/25Cr and nickel-alloy tubing for CO2 and H2S environments.
