The 3 1/8" Choke Manifold 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.
