High Pressure Annular Blowout Preventer Wellhead Equipment
Product Description
Annular Blowout Preventer consists of forged alloy steel housing and elastic rubber packing unit. Driven by hydraulic power unit, the internal rubber core deforms evenly to wrap various sizes of drill pipe, joint, kelly bar, or fully close the well without pipe inside. It can coordinate with ram BOP to build complete well control stack for onshore and offshore rigs. The body adopts integral forging with anti-corrosion supersonic spraying, supporting long-term service under high pressure, hydrogen sulfide and seawater environment. All units pass API 16A full performance test, PR2 grade optional for heavy-cycle harsh working conditions.
Product Features
- Omni-directional sealing design, fits different drill pipes, connectors and empty wellbore
