Manifold
Ram BOP
Single and double ram type BOPs are widely used in oilfield and offshore platform. They have the features of compact structure, easy handling and reliable seal. The pipe ram adopts the pressure increasing seal way, which makes it seal drill tool rapidly and efficiently, even remain its seal effect after the disappearance of fluid control pressure.
The open or close of ram preventor and ram replacing are both hydraulically controlled. The onsite replacing of pipe ram and sealing parts saves much time.
•Driving mode：Manual & hydraulic
•End connection：Flanged and bolted
•Working pressure：2000~10000PSI
•Nominal bore：90mm、120mm、179.4mm、279.4mm、346mm
•Executive standard: API 16A and relevant specification
Annular BOP
In case of blowout and well-sealing is needed,high pressure oil coming from control system enters the bottom closing chamber from bottom inlet to push piston moving upward.The movement of piston forces tubber core to move upward along the sphere surface, then supporting ribs get closer to push the internal rubber towards the wellhead center to fulfill the function of sealing drill equipment or the wellhead. When unlocking the seal is needed,hydraulic oil pushes the piston moving downward and the rubber core will reset to its original under its elastic force.
Structure Characteristics
1.The connection between top cap and housing ,top and bottom ends adopt flanges and bolts.
2.Semisphere rubber core has many advantages,such as not easy folding back, big volume of rubber storage.Under the well pressure,the piston pushes the rubber core upward to form a funnel shape.The funnel effect of rubber core increases its sealing performance and life span.
3.Characteristics of the sealing structure
Choke and Kill manifold
Choke manifold and Killing manifold are the important well control equipments to carry out close balance drilling in petroleum exploration. During well drilling process, these equipments can keep oil reservoir from pollution and efficiently control well blowout. That product designs a manufacturing according to the API Spec 16 C standard, the machine function is good, sealing completely credibility, the function is well-found, operating convenience.
