Well Controls
BOP and Components

Blowout Preventer A large valve, usually installed above the ram preventers, that forms a seal in the annular space between the pipe and well bore or, if no pipe is present, on the well bore itself.



We offer more than 40 kinds of Blowout Preventers with pressure ranging from 500 psi to 15000 psi and diameter from 7 -1/16 to 29-1/2 and cable BOP, non-kill BOP diverter, rotating BP and so on. Furthermore, we can develop and manufacture other kinds of BOP on customers request. The blowout are designed and manufactured by absorbing the advantages of the world famous BOP manufactures in structural design. It complies with the technical requirements of well control in drilling, workover and oil testing.


Kill and Choke



Manifold Choke

Manifold The arrangement of piping and special valves,called chokes, through which drilling mud is circulated when the blowout preventers are closed to control the pressures encountered during a kick.
