Drilling rig Wellhead control API 16C Choke manifold

Product Description

Application of API 16C Choke manifold                            

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 prevent the pollution of oil-layer, improve the speed of drilling and control blowout effectively. One end of the devicecon nects 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, so balanced drilling can work under minimum pressure-difference.

Assembly & structure of API 16C Choke manifold              

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

Working principle of API 16C Choke manifold

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 as the casing pressure is quite high.

Specification details of API 16C Choke manifold

Pressure level is divided into five levels, i.e. 2,000psi, 3,000psi, 5,000psi, 10,000psi, 15,000psi; it can be designed according to the requirement of customer.

Operation requirement

(1)All the working pressures of parts in choke manifold should be matched with the working pressure of the BOP stack used;

(2)Choke manifold should be installed at the place where operator approach it conveniently, pressure test should be executed as installation, while the sealing test pressure should equal to the rated working pressure;

(3)Pipeline should be so smooth and straight as possible, the corner of the pipeline should be made of 120°shaped forged steel bent pipe, which should have adequately large bore.

(4)The working pressure gauge should be installed.

(5) In winter, the choke manifold be able to work under a low temp condition.
