2 1/16" -3000psi Choke Kill Manifold For Oil Well
The Choke Kill Manifold is the essential well-control devices to control overflow and blow-out,and also to approach the balance pressure drilling .the Choke Kill Manifold is applicable for controlling casing pressure by use of pressure relief and blowout,and for maintaining the pressure balance inside the well bore and hence protecting the wellhead.the kill-line manifold is applicable for killing operation to pump the killing fluid into the down-hole,which prevents accidents from happening and insures production safety.

Configuration
The choke manifold consists of choke valves, gate valves, line pipes, fittings, pressure gauges, and other components.
Working Principles
When the pressure inside the well rises, opening/closing the choke valves(including manual chokes, hydraulic chokes, and positive chokes)on the choke manifold can allow the release of the fluid inside the well to control casing pressure, which can be directly blown out through the gate valve if the casing pressure is quite high.
4. Pressure Ratings
The kill manifold is available in pressure ratings of 2000psi,3000psi,5000psi,10000psi, and 15000psi, and also can be available upon customer request.
Operating Instructions
(1) The working pressure of all components on the choke manifold shall be compatible with that of the BOP stack used.
(2) The choke manifold shall be installed at a place where the operator can reach it easily. The pressure test must be performed before installation and the seat test pressure shall be equal to the rated working pressure.
(3) The line pipe shall be level and straight as much as it could. In case of the turn of the line pipe, the 120-degree steel bent pipe shall be used. The bore of the line pipe shall be large enough.
(4) The pressure gauge must be installed.
(5) In winter, the choke manifold can work under a low-temperature conditions.
