The Choke Manifold consists of choke valves, gate valves, pipes, fittings, pressure gauges and other components. It is a necessary device of controlling the well kick and executing the pressure control on oil & gas in the process of well drilling and producing. When BOP is closed, it can control the final pressure from casing by adjusting the opening & closing of the choke valve, which avoid pollution of oil-layer and improve the speed of drilling and control blowout effectively. Also in well testing and producing, choke manifold is used to control the crude oil and gas flow rate and pressure to achieve a proper yield to avoid following equipment's overpressure and overloading by changing the choke beans.
