Description

The choke manifold is used to control well kick and well pressure. The operator can control the open/close angle of the choke valve to control the casing pressure, keeping the balance of downhole pressure or making it a little above the surface pressure to avoid overflow or blowout.

We can provide customized choke manifold depending on customers' requirements.

Feature


  • The design, manufacture and inspection of choke manifold conform to API Spec 16C Specification for choke and kill systems, and NACE MR0175 Metals for sulfide stress cracking and stress corrosion cracking resistance in sour oilfield environment.
  • Flanges are connected by bolts and adopt pressure energized ring gasket to deliver reliable sealing performance. 
  • With the chocking effect, the choke valve controls the drilling process and the pressure of wellhead casing and riser by replacing the contaminated mud downhole, restoring the mud column control over the downhole pressure to avoid overflow and blowout. 
  • With the blowdown effect, the choke valve can realize “soft well shutoff” by reducing the wellhead casing pressure. 
  • With the large discharge capacity, the bleeder valve is designed to protect the BOP stack by reducing the wellhead casing pressure.
