Detailed information

1. Application

Choke manifold is a necessary equipment for well kill and pressure-control process. Besides the normal size and pressure, we may design and manufacture according to the customer's requirements.

It can prevent the pollution oil-layer, improve the speed of drilling and control blowout effectively. One end of the device connects with the side flange of BOP spool. When BOP closes, it can control the finite pressure from casing by adjusting the choke valve's opening.

2. Assembly & structure

Choke manifold consists of choke valve, gate valve, pipeline, fittings and pressure gauge etc.

3.Working Principle

When the pressure rising in well, fluid in well can be released in utilization of the choke valve opening/closing in choke manifold to control casing pressure, which can directly blow out through gate valve when the casing pressure is quite high.


Pressure level is divided into six levels, 2000PSI, 3000PSI, 5000PSI, 10000PSI, 15000PSI, 20000PSI; it can be designed according to the requirement of client.


Choke manifold is according to the requirements of API Spec 16C

Working Pressure: 2,000PSI ~ 20,000PSI

Nominal Bore Size: 2 1/16” ~ 4 1/16
