The choke manifold is a necessary piece of equipment used for controlling the well kick and implementing oil-gas well pressure control technologies
- Through opening and closing the choke valve it can control certain pressure so as to maintain a bottom hole pressure that is higher than the formation pressure;
- It is also used for blowout protection (BOP) in order to protect the wellhead in the event that in-hole pressure exceeds certain limits;
- The throttle manifold is composed of a choke valve, gate valve, pipeline, fittings, pressure gauge, etc.
|Pressure (psi)||2000 – 20000|
|Nominal Diameter (in)||2 1/16 – 4 1/16|
