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.

 Through relief pressure, decrease wellhead pressure to perform “Flexibility Shut Off Well”.

  Through drain valve, decrease casing pressure of wellhead to protect BOP stack.

  Furnished with hydraulic control pod to achieve the function of remote control.
