Providing Repair Kit for Combi BOP


During coiled tubing operations, combi BOP can be equipped with quad BOP to protect against blowout. The combi rams can realize pipe seal, pipe cut, pipe clamping and complete well seal which is suitable for high-pressure wellhead control and H2S service.
Ram open and close are controlled hydraulically with quick response and remote control. The manual lock capability ensures reliable BOP shutoff.  The designed hydraulic system facilitates quick and easy ram change without having to remove the hydraulic cylinder from the BOP. Besides combining functions of conventional quad BOP, the combi BOP features compact structure, light weight, high efficiency and low maintenance cost.
We can provide customized combi BOP depending on customer's requirements.
