The Choke Manifold is a sort of high pressure manifold used in oil well drilling operation and testing operation, it is the important wellhead equipment to carry out the pressure control technology in the oil/gas well. The choke manfiold with high working pressure is used for controlling casing pressure, keeping wellbore pressure balance, to avoid overflowing and prevent wells from blowing out, releasing pressure through choke valves to realize soft closing, and blowing down to protect the wellhead. The choke manifold can be provided with the hydraulic control manifold for the remote control. The choke manifold manufactured by our company conform to API Spec 16c and NACE Standard MR0175.

Working principles of the Choke manifold

When the pressure inside the well rises, opening/closing the choke valves(including manual chokes, hydraulic chokes and positive chokes) on the choke manifold can allow the release of the fluid inside the well so as to control casing pressure, which can be directly blown out through the gate valve if the casing pressure is quite high.
