API 16RCD High-Integrity Rotating Control Device (RCD) System for MPD & UBD Operations

  • Conventional BOP stacks cannot maintain continuous dynamic annular sealing on rotating drill strings during pressurized drilling and MPD/UBD operations.
  • Built to API Spec 16RCD standards, our Rotating Control Device (RCD) system delivers robust dynamic sealing (17.5 MPa) and high-speed rotation (60–120 r/min) with integrated hydraulic control.
  • Ideal for managed pressure drilling (MPD), underbalanced drilling (UBD), and tripping under pressure with air, foam, or conventional drilling fluids.

Main Advantage & Solution

  • Dynamic sealing failure and rapid bearing wear during high-speed rotating drilling under pressure.
    Solution: Advanced dynamic seal core assembly paired with dynamic oil lubrication and cooling systems, supporting continuous operations at 17.5 MPa dynamic pressure and speeds up to 120 r/min.
  • Complex wellhead integration and unsafe tripping operations under annular pressure.
    Solution: Flanged bottom interface for direct mounting above annular/ram BOPs; fully compatible with non-snubbing tripping equipment, back-pressure valves, and mud-gas separators.

Application Scenarios

  • For MPD / UBD Drilling Contractors: Continuous annular sealing and return mud diversion during managed pressure drilling, underbalanced drilling, and air/foam drilling.
  • For Well Control & Snubbing Services: Secure containment during pressurized drill pipe rotation and stripping/tripping operations in combination with hydraulic BOP stacks.
