API Choke Manifold And Kill Manifold 2 9/16" 5000psi
Choke Manifold And Kill Manifold is the necessary equipment to control well kick and implement pressure control technology of oil and gas wells. When the BOP is closed, the choke valve is used to control the casing pressure to maintain the bottom hole pressure slightly greater than the formation pressure and to prevent further formation fluid flow into the well. In addition, choke manifold can be used to relieve pressure to achieve soft shut-in.

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.
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.
