A BOP stack can well function in different environments of low or high temperatures or rich in sulphur. The blowout preventer assembly can meet diverse well control demands in processes of drilling, well testing and underground drilling. Our BOP stack ranges from 2 9/16" to 30" in its nominal diameter and from 3.5MPa (500psi) to 140MPa (20000psi) in the working pressure. The stack adopts a forged or cast body and can be closed manually or hydraulically.

A choke manifold is a common device in a well-control system to control kicks. The manifold uses choke valves to adjust flows and pressures in various well applications, minimizing equipment damage. Designed and produced by standards of API Spec 16C and 6A, all models of the kill manifolds are made from anticorrosive materials which can also withstand the washing of drilling fluids and prevent leakages, ensuring safe and reliable operation.
