Oil Gas Drilling Wellhead Choke Kill Manifold High Pressure
Oil & Gas Wellhead High Pressure Choke Manifold & Kill Manifold
The Choke Manifold is necessary device to control the well kick successfully and execute the pressure control technology on oil&gas well during the drilling operation. In case that the BOP is off, the pressure at the bottom of well shall be kept higher than formation pressure through controlling casing pressure with choke valve on-off. The choke line manufactured by our company conforms to the API 16C, NACE MR0175 Standards
Choke manifold composes of choke valve, gate valve, flanged pipe and pressure indicator. When the pressure in well increases, the pressure can be relieved by opening and closing the choke valve (manual, HYD and fixed) on choke manifold.
