Key Features

  • 10,000 PSI High-Pressure Rating: 10,000 psi working pressure with 15,000 psi hydrostatic body test — suitable for high-pressure well control scenarios
  • API SPEC 16A Compliant: Designed and manufactured to international drilling equipment standards for annular blowout preventers
  • Hydril-Style Interchangeable Design: Structurally equivalent to Hydril annular BOPs with fully interchangeable sealing elements for easy maintenance and global parts availability
  • NACE MR-0175 Compliant: Suitable for H2S sour service environments with appropriate material selection and hardness control
  • Ni-Based Alloy 625 Кольцо Grooves: All ring grooves welded with nickel-based alloy 625 stainless steel for superior corrosion resistance at high pressures
  • 5 Major Components Only: Simplified assembly with only five main structural parts for reduced maintenance complexity and higher reliability
  • Acme Thread Корпус-Head Connection: Heavy-duty Acme threaded connection between upper housing and lower housing for secure pressure containment
  • Wear Кольцо Protection: Moving parts equipped with wear rings (upper housing, lower housing, piston) to prevent metal-to-metal contact and extend ПВО service life
  • Easy Уплотнение Element Replacement: Sealing element can be replaced without disassembling or removing hydraulic connections — reduces downtime
  • Full Bore Sealing Range: Seals on pipe sizes from 0 to 7 1/16″ for maximum operational flexibility including stripping operations
  • BX156 High-Pressure Connections: API BX156 studded top and flanged bottom for secure high-pressure wellhead integration
  • T-20 / BA Temperature Rating: Metal rated -29°C to +121°C (T-20); non-metal seals rated -18°C to +82°C (BA)
