4 1/16 Inch 5000psi Kill Manifold Drilling Rig Spare Parts
Kill Manifold is mainly composed of a one-way valve, gate valve, pressure gauge, connecting pipeline, etc. One end of it is connected with the BOP and the other end is connected with the injection pump. The kill manifold and choke manifold are designed according to APl 16C standard. The working pressure of all pipelines, gate valves, check valves, etc. must match the working pressure of the blowout preventer used; the kill manifold cannot be used as a pipeline for daily drilling fluid injection.

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.
