2 9/16" 20000psi Choke And Kill Manifold Drilling Equipment
The choke And Kill Manifold is used during well testing, The positive choke has a fixed diameter and the size of the orifice on the adjustable choke can be varied. In addition, the adjustable choke allows fixed chokes to be switched out as needed without stopping the well, increasing the flexibility of the overall system.

Choke And Kill Manifold 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 Choke And 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.
