Product Name: Lift Type Choke Manifold with API 16c Model NO.: api 16c Certification: API 16c, ISO Type: Petroleum Drilling Machine Usage: Well Drilling Machinery Trademark: JIELIN Transport Package: Wooden Case Box Specification: API 16c Origin: China Product Description Lift type Choke manifoldChoke manifold is a necessary device for controlling well kick and implementing oil-gas well pressure control. When blowout preventer is closed, choke valve can be turned on and off to control certain casing pressures to keep bottom hole pressure a little higher than formation pressure all the time, lest formation fluid should further flow into well. Besides, when well is shut off, choke manifold can be relieved for the realization of soft shut-in. When the pressure rises to a certain level, it can be used to open the well for gushing so as to protect the well.Choke manifold is composed of choke valve, gate valve, pipeline, pipe fittings and pressure gage, etc.When well pressure rises, the choke valve (it falls into three kinds: Manually adjustable, hydraulic and positive) on choke manifold can be turned on and off to release the fluid to control casing pressure. Gate valve can be used for direct blowout. When casing pressure is pretty high,The pressure class of our company's chokes manifold falls into five class: 14MPa, 21MPa, 35MPa, 70MPa and 105MPa. Also, we can design according to customer demand.NameChoke manifoldKill manifoldModelJG/S2-35JG/SY-35JG/SY2-70JG/S2Y2-105YG-35Y-70YG-105Main diameter and sideward diameter31/8× 21/16(80× 52) 41/16× 29/16(103× 65) 41/16× 31/16(103× 78) psi(MPa)Working pressure psi (MPa)3000(21)5000(35)3000(21)10000(70)5000(35)10000(70)15000(105)(° F)Working temperature º C (° F)LU -46º C ~ +121º C (-50° F ~ 250° F)Working mediumsDrilling fluid, mud and petroleum (with sulfuretted hydrogen)Control typeTwo-winged manual choke valveTwo-winged hydraulic manual choke valveThree-winged hydraulic manual choke valveFour-winged double-hydraulic manual choke valveTwo-winged main relief valve
