Fix drilled wellhead, connect wellhead casing string. Seal and control the annular space between the tubing, suspension, control and regulation of wellhead pressure oil ( gas ) well flow, and can induce oil into outlet pipeline, if necessary, can also be used to shut off well, can also be used for acid fracturing, water injection, […]

When full ram seals well, inject weighted mud into well bore to perform well killing. When well blowout occurred, inject water into well through kill manifold to prevent be on fire. When the well is on fire, inject extinguishing agent into well bore through kill manifold to put out fire.

The seat design of a lift-Check valve is similar to a Globe valve. The disc is usually in the form of a piston or a ball. Lift Check valves are particularly suitable for high-pressure service where velocity of flow is high. the disc is precisely guided and fits perfectly into the dashpot. Lift Check valves […]

Split-type body and trunnion ball design, to avoid excessive pressure on the valve seat and damaged seat. The ball and the valve stem are designed and processed in an integrated manner to ensure the ball and stem in the centre line of valve, and avoid the valve stem disengagement by the frequent opening. Used Inconel […]

Full port or reduced port Floating ball or trunnion ball Metal to metal seated Blowout-proof stem Fire safe design to API 607 / API 6FA Anti-static to BS 5351 Cavity pressure self relief Double seats with spring loading

Mud gate valve is mainly used for mud circulation system of oil field or mine to control the mud flow and close. They are buttress threaded connected, easy for quick installation with great rigidity, safety and reliability. Parallel-type elastic sealing between valve seat and gate has good sealing performance and is easy to open. Connection […]

Mud manifold converges and shunts mud in drilling operation, and transport mud sufficiently and reasonably to standpipe manifold, so that there is plenty of mud through the top drive to proceed with drilling operation.

Fix drilled wellhead, connect wellhead casing string. Seal and control the annular space between the tubing, suspension, control and regulation of wellhead pressure oil ( gas ) well flow, and can induce oil into outlet pipeline, if necessary, can also be used to shut off well, can also be used for acid fracturing, water injection, […]

Full bore design eliminates efficiently pressure drop and vortex, eliminates washing by solids in fluid. Mental-to-mental seal is used between bonnet and body, gate and seat, body and seat. The surface of gate and seat is weld overlay with hard alloy, which has feature of corrosion resistance and washing resistance. The bonnet and stem designed […]

Hydraulic ram blowout preventer is the important component of well control device which has characteristics of flexible switch, easy operation , safe operation, simple maintenance.etc. Ram Structure and Operation Characteristics. Double sides of the gate can be used, and the upper and down sides of gate are symmetrical. Different sizes of drilling tools only need […]
