Product Name: API 16c Choke Manifold in Wellhead Model NO.: Choke Manifold Material: Alloy Operation Pressure: Atmospheric Pressure Transport Package: Plywood Box Specification: 2-1/16" ~ 4-1/16" Origin: China Product Description General DescriptionChoke 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)SpecificationsDesign & Manufacture:API SPEC 16C /API SPEC 6AConnection: Threaded, Flanged or Union connectedNominal Diameter: 2-1/16" ~ 4-1/16"Working Pressure: 2000PSI~15000PSIMaterial grade: EE, FFBody Material: Carbon steel 10#,20#,1045; Low-alloy steel ASTM4130; Stainless steel 410,17-4PH,CRAbApplicationChoke manifold is a necessary device in pressure control of oil and gas and the prevention 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 the choke valve. When the pressure in the well rises at a limited level, it can be used to prevent blowout and protect wellhead.about TAVAL
