API 16C Choke Manifold Features:1) Working pressure: 2000PSI 20000PSI 2) Nominal Bore: 2.1/16" 4.1/16" 3) Working Medium: oil, natural gas, mud 4) Working Temperature: -46°C 121°C(Class LU) 5) Material class:EE,FF 6) Executive standard:API SPEC 16C Choke manifold is necessary support equipment to control well blow out and well pressure. It consists of choke valves, gate valves, line pipes, fittings, pressure gauges and other components. The choke manifold is support equipment of hydraulic BOP for controlling well blow out and well pressure. Through the choke valve, perform well killing, replacing polluted slurry in well. Control wellhead pressure of casing and standpipe, restoring mud to control pressure at well bottom to stop overflow.
