Solution Brief

Suitable for both onshore and offshore oilfields with high levels of hydrogen sulfide and special requirements for the sulfur-resistant performance of well control equipment. Hydrogen sulfide not only causes damage to the equipment but is also highly toxic and can cause serious harm to people, making higher well control requirements necessary for high-sulfur work environments.
To address these challenges, we provide a complete set of high-sulfur-resistant solution for our clients. These solutions include special processes for the flow passages that come into direct contact with well fluid, such as welding of corrosion-resistant special materials or nickel-based alloys (our company has advanced automated welding equipment processes to allow complex shapes to be welded); key non-metallic sealing components such as rubber cores and seals that come into direct contact with well fluid are made of special rubber materials that are suitable for high-sulfur environments; the surface of piston rods that come into direct contact with well fluid are coated with special corrosion-resistant materials for reciprocating movements. We provide a range of high-sulfur-resistant well control equipment, including blowout preventers, pipe manifolds, and four-way valves that cover all sizes and pressures.
