Strong corrosion from seawater, high pressure underwater (at the wellhead), and vibration and shock from the platform
✔ Material: 2205 duplex steel and titanium alloy Gr5 are used underwater
✔ Process: Sandblasting anti-corrosion treatment, static pressure test, and hard alloy surfacing on the sealing surface
API 6A and API 6D certifications
High-pressure long-distance transportation, hydrogen sulfide corrosion, etc
✔ Material: Forged steel/cast steel for high pressure; For LNG scenarios, 36Ni9 low-temperature steel + nickel-based seals are equipped
✔ Process: Anti-sulfur stress corrosion treatment for sulfur-containing working conditions
API 6D certification, pressure coverage 2500LB/10000PSI
Strong corrosive media (acids, alkalis/solvents), high cleanliness requirements, pressure fluctuations
✔ Material: Hastelloy C276 and titanium alloys for strong corrosion; Conventional 316L stainless steel/cast steel WCB is used
✔ Process: Degreasing and oil-free treatment of special material valves, and laser cladding of hard alloy on the sealing surface
API 608, ASME B16.34 certification, ISO certification
High pressure (wellhead/pipeline), high sulfur content corrosion, sand erosion wear
✔ Material: API 6A forged steel/cast steel valve body, 22Cr super duplex steel, Inconel 625 special material for high-sulfur scenarios
✔ Process: The valve core is coated with tungsten carbide to resist wear and is forged as a whole to prevent high-pressure leakage
