While traditional valves require frequent replacement in sulfur-bearing oilfields, OUWEI fully welded ball valves are upending industry norms with a 3-year zero-maintenance track record.
✅ Material Revolution
Crafted with a duplex steel 2507 valve body and nickel-based alloy overlay seal face, hydrogen sulfide corrosion resistance is increased by 10x, with lab-tested corrosion rate of only 0.03mm/year (vs. industry average of 0.3mm/year).
✅ Structural Innovation
One-piece fully welded construction eliminates flange leakage risks. It passes the API 6FA fire test, maintaining zero leakage even in 1000℃ open flames, delivering dual protection for high-risk operating conditions.
✅ Efficiency Leap
Pneumatic actuator enables ultra-fast opening/closing in 0.5 seconds, 80% faster than traditional valves, boosting single-well daily production by over 15%.
