Watch as we perform a zero-sealing test on the Shaffer Bolt Cover Type Annular BOP with 13 5/8" bore and 10,000 psi working pressure. You'll see how this high-reliability pressure control equipment delivers stable sealing performance during critical drilling operations, demonstrating its compact design and efficient operation under demanding conditions.
Related Product Features:
  • Compact design with 15-20% lower height than comparable annular BOPs for installations with limited vertical space.
  • Operates at low hydraulic pressure of 1,500 psi, reducing accumulator size requirements and associated costs.
  • Durable sealing element with steel reinforcement provides 2-4 times longer service life than conventional elements.
  • Universal sealing capability on various downhole tools including drill pipes, tool joints, casing, and wireline tools.
  • Simplified maintenance with easy upper housing removal and no complex tools required for routine servicing.
  • Suitable for internal H₂S service as standard with optional external H₂S conversion and Arctic models available.
  • Wear rings eliminate metal-to-metal contact on moving parts, extending component service life.
  • Minimal hydraulic connections with only two ports for opening and closing simplify system integration.
FAQs:
  • What is the maximum working pressure of this Shaffer Annular BOP?
    This Shaffer Bolt Cover Type Annular BOP has a rated working pressure of 10,000 psi (69 MPa) and a hydrostatic test pressure of 15,000 psi (103.5 MPa), making it suitable for high-pressure drilling applications.
  • Can this BOP handle sour service conditions with H₂S?
    Yes, the BOP is suitable for internal H₂S service as standard and can be converted for external H₂S service. All metallic materials in contact with well fluids meet NACE MR0175 requirements for sour service.
  • What are the temperature operating ranges for this annular preventer?
    Standard models with nitrile elements operate from 40°F to 180°F (4°C to 82°C), while specialized Arctic models are available to meet low-temperature API 16A requirements for harsh environments.
  • How does the compact design benefit drilling operations?
    The compact design features 15-20% lower height than comparable annular BOPs, making it ideal for installations with limited vertical space while maintaining full performance capabilities.
