PIONEER ENERGY
High-sulfur-resistant BOP Stack
Reference standards:API 16A、GB/T 20174
Product Applicability: For well control operations under high-sulfur conditions, the BOP stack has a corrosion resistance meeting the requirements for resistance to high hydrogen sulfide, and is suitable for occasions with hydrogen sulfide content ≥ 35%, equivalent to the HH level hydrogen sulfide in API 6A.
Product Features

  • Suitable for environments with high sulfur content, such as land and offshore platforms, which have special requirements for the anti-sulfur performance of the BOP stack. 

  • The inner cavity of the equipment that contacts the well fluid is welded with high sulfur resistance alloys. 

  • Key non-metallic sealing components, such as the rubber core and side door seal, that come into contact with well fluids are made of special materials suitable for high sulfur content environments. 

  • Inconel is done by using imported equipment and assisted by sophisticated testing and monitoring methods to ensure product quality.
