Choke Manifold
Description
Technical Parameters
Choke manifold is necessary device to control the well kick successfully and execute the pressure control technology on oil/gas well in the course of drilling, as it is,the device is adopted to execute new drilling-well's technique of balance pressure,which can avoid pollution of oil-layer,improve the speed of drilling and control blowout effectively.
Kill Manifold consists of check valves, gate valves, pressure gauges and line pipes. One end of the kill manifold is connected to drilling spool and the other to pump.Kill manifold is necessary equipment in well-control system to pump drilling fluid into well barrel or inject the water into wellhead.
Our company’s choke and kill manifold falls into five class: 14MPa, 21MPa, 35MPa, 70MPa and 105MPa. Also, We can design according to customer demand.
