General Description
Choke manifold is usually made of choke valves, gate valves, piping, pipe fittings, pressure gauges and other components. The system is suitable for places where acid fluid may go through. And its metal materials in contact with fluid in the well shall meet the requirements of NACE, API6A, PSL3 (or higher)
Specifications
Design & Manufacture:API SPEC 16C /API SPEC 6A
Connection:Threaded , Flanged or Union connected
Nominal Diameter: 2-1/16" ~ 4-1/16"
Working Pressure: 2,000PSI~15,000PSI
Material grade: EE, FF

Application
Choke manifold is a necessary device in pressure control of oil and gas and the prevension of well kicks. When BOP is off, the pressure in the wellbore shall be kept higher than that of the formation fluids by the switch of choke valve. When pressure in well rises at the limited level, it can be used to prevent blowout and protect wellhead.
