FAQs:
  • What are the main operation modes for the Shaffer Ram BOP?
    The Shaffer Ram BOP supports dual operation modes: hydraulic control for quick ram opening/closing within 3-15 seconds, and manual locking for maintaining ram position during long-term well sealing without continuous hydraulic pressure.
  • How does the sealing system ensure reliability in the Shaffer BOP?
    The sealing system provides dual protection through four key sealing points (ram top with body, front seal with string, body with bonnet, ram shaft with bonnet) combined with well pressure-assisted sealing, where downhole pressure pushes the ram against sealing surfaces for enhanced reliability.
  • What maintenance features are designed into the Shaffer Ram BOP?
    Maintenance features include a hinged bonnet for easy access, internal buried hydraulic oil circuits to prevent damage, high support ribs and sand-settling surfaces to reduce friction, and accessible components for ram and seal replacement.
  • What pressure ratings and bore sizes are available for the Shaffer Ram BOP?
    The Shaffer Ram BOP offers bore sizes including 7 1/16", 9", 11", 13 5/8", 16 3/4", 21 1/4", and 26 3/4", with rated working pressures ranging from 2000psi (13.8MPa) to 15000psi (103.4MPa).
