Choke Manifold is used to lower the pressure from the wellhead in oil & gas production. It consists of a set of high pressure gate valves, studded cross, flow line, flange, and at least two choke valves. These chokes can be fixed or adjustable or a mix of both. The redundancy is needed so that if one choke has to be taken out of service, the flow can be directed through another one. By lowering pressure the retrieved gas can be flared off on site.

All of our Choke and Kill Manifolds are fully designed, manufactured, and tested in accordance with API 6A & API 16C standards. Service applications range from noncorrosive to extreme sour oil and gas. Qihang's drilling chokes, manual or hydraulic, allow maximum operational flexibility and control in working pressures from 2000 psi to 15000 PSI, as well as field-replaceable components that simplify maintenance. All manifolds can be controlled remotely or via a local control panel.
