Choke Manifold



Choke Manifold is neccessary equipment for well control and implementation of well pressure control technology during drilling process.Using this equipment,we can implement balanced pressure drilling technology to prevent oil pollution and improve drilling speed.



The choke manifold consists of choke valves, gate valves, line pipes, fittings, pressure gauges and other components.


Working Principles

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.


Pressure Ratings

The kill manifold is available in pressure ratings of 14MPa, 21MPa, 35MPa, 70MPa and 105MPa, and also can be available upon customer request.


Operating Instructions

  1. The working pressure of all components on the choke manifold shall be compatible with that of the BOP stack used.
  2. The choke manifold shall be installed at the place where the operator can reach it easily. The pressure test must be performed prior to installation and the seat test pressure shall be equal to the rated working pressure.
  3. The line pipe shall be level and straight as much as it could. In case of the turn of the line pipe, the 120 degree steel bent pipe shall be used. The bore of the line pipe shall be large enough.
  4. The pressure gauge must be installed.
  5. In winter, the choke manifold can work under a low temperature condition.
