Providing Repair Kit for Quad BOP


Quad BOP is designed for protection against blowouts for coiled tubing operations. During overflow, well kick and blowout, the BOP can quickly shut off the well, perform well killing and restore wellbore pressure balance.
The BOP rams are operated with hydraulics. There is a manual lock mechanism to lock the actuators closed or used to close the rams in case of hydraulic system failure in an emergency. The second hydraulic system design allows quick access to change or service rams by disassembly of actuators form the body.
Internally ported hydraulics eliminates the breaking of oil seals when servicing or changing rams, thus reducing the risk of environmental pollution.

We can provide customized Quad BOP depending on customer's requirements.


  • Available with a 2-1/16"BX-152 standard side flange for slurry circulation, throttling and well killing.
  • The top and bottom portions are connected by standard or other types of flanges or unions to meet customers various demands.
  • Ram design is available in Single, Twin, Triple and Quad. Rams are controlled by hydraulics with simple configuration and quick response which can shut off the well within 3 to 8 minutes.
  • Each actuator can be locked manually in case of hydraulic failure.
  • The second hydraulic system allows quick and easy ram service or change without having to remove the hydraulic cylinder from the BOP.
  • Quad BOP comprises of blind, shear, slip and pipe rams, suitable for various tubing sizes.
  • The equalizing mechanism evenly distributes wellbore pressure in the body to avoid pressure fluctuation due to ram open.
  • A debooster is optional depending on customer needs which can reduce the pressure to 1/4 shown on the pressure gauge, thus safeguarding operation safety.
