Frequently Asked Questions
What valves are used in offshore oil and gas?
Offshore platforms use ball valves for isolation and control, gate valves for full-bore isolation, check valves for pump protection, butterfly valves for large diameter applications, and choke valves for flow control. Materials include Duplex 2205, Super Duplex 2507, 254 SMO, and Inconel.
What is API 6DSS?
API 6DSS (Specification for Subsea Pipeline Valves) covers design, manufacturing, and testing requirements for ball, check, and gate valves used in subsea pipeline applications. It specifies requirements for materials, welding, testing, and quality control for valves operating in subsea environments.
What materials are used for subsea valves?
Subsea valves typically use Super Duplex 2507 (UNS S32750) for bodies and bonnets due to its high strength and corrosion resistance. Inconel 625 or 725 is used for stems and critical components. Stellite or tungsten carbide coatings are applied to sealing surfaces.
Do you supply valves for FPSO projects?
Yes, we supply valves for FPSO (Floating Production Storage and Offloading) vessels including topside process valves, seawater systems, ballast systems, and cargo handling. We work with major FPSO contractors and operators worldwide.
