BOP Stacks

Ram BOPs

The ram BOP has three Structure styles as RSC, RSF and RSH.
Bore size (in): 9-26 3/4.
Working pressure range psi (MPa): 3 000-15 000 (21-105).

Annular BOPs

The annular BOP has two structural styles including Model A and Model D.
Bore size range (in): 7 1/16-21 1/4.
Working pressure range psi (MPa): 3 000-10 000 (21-70).

Rotating BOPs

Rotating BOP is developed for the control of underbalanced drilling. It mainly consists of drilling pipe driver, bearing assembly, sealing rubber, hub assembly and body.

Kill Manifold and Choke Manifold

The choke manifold is necessary to control well-kick & blowout and put the pressure control technology on oil/gas well into force.
The kill manifold is a necessary part in well-control assembly, its function includes as follows:
To pump drilling fluid into well barrel to control the pressure in oil/gas well;
To inject the fresh water into wellhead so as to avoid fire and burn as blowout;
To inject extinguishant into well barrel as blowout and on fire.
