Check valves are used to prevent the reverse flow of fluid. The principle of operation of the check valve is that the valve is opened by the flow of fluid,

Valves are essential components of oil refining and petrochemical pipeline systems. Its primary function is to connect and cut off the logistics, and adjust the pressure, flow, emptying, and discharging,

Rotary BOP is a dynamic sealing device for drilling under negative pressure, foam and air. It is often using to close the wellhead during oil testing, workover, completion and other

The factors affecting the drilling speed are mainly geological and engineering factors. Along with China’s oil and gas industry has entered the late stage of development, how to improve the

(1) Expansion valve 1, in the switching process, the oil valve plate thickness is minimum, reduce the valve plate and seat sealing surface wear, reduce the switching torque 2, valve

overview During drilling operations, to prevent formation fluid intrusion into the well, keep the drilling fluid column pressure slightly higher than the formation pressure at all times. However, in the
