Well control equipment, choke manifold Choke manifold is necessary device to control the well kick successfully and execute the pressure control technology on oil/gas well in the course of drilling, as it is, the device is adopted to execute new drilling-well's technique of balance pressure, which can prevent the pollution of oil-layer, improve the speed of drilling and control blowout effectively. One end of the devicecon nects with the side flange of bop spool. When bop closes, it can control the finite pressure from casing by adjusting the choke valve's opening, so balanced drilling can work under minimum pressure-difference. Fabrication of choke manifold is according to the requirements of API spec 16c. Working pressure: 2, 000psi - 15, 000psi Nominal bore size: 2.1/16" to 4.1/16"Model Working Pressure Inlet Outlet Valve Control JG-21 3000 3-1/8"-3000psi 3-1/8"-3000psi Manual and Hydraulic JG-35 5000 3-1/8"-5000psi 3-1/8"-3000psi Manual and Hydraulic JG-70 10000 3-1/16"-10000psi 3-1/8"-5000psi Manual and Hydraulic JG-105 15000 3-1/16"-15000psi 3-1/16"-10000psi Manual and Hydraulic Working Temperature:-20-250°F Specification Level:PSL1-PSL4 Material Class:AA BB CC DD EE FF Performance Level:PR1-PR2 Working Medium:Mud,Petroleum,Natural Gas
