Chock and Manifold

1.Application Purpose
The Choke Manifold is an essential equipment to control well kick and implement (he oil and gas well pressure control technology. Under
the BOP closed conditions, the use of the throtle valve's opening and closing (o control a certain casing pressure in order to maintain chat
the downhole pressure is always slightly larger than (he formation pressure, so as to prevent the formation fuid further flow into lhe wel. in
addition, during the implementaion of wel shutdown, it is avalable to achieve a soft shutdown by virtue of pressure relief via the choke
manifold. When the well pressure rises to a certain limit, it is able to protect the wellhead through blowout prevention.
2.Composition and Structure
The Choke Manifold is constituted by the throtle valve, gate Valve, pipes, pipe fitings, pressure gauge and other components
3.Working Principle
When the well pressure increases, it is able to release the well fluids to conirol the casing pressure through opening and closing the throitle
valve on lhe choke manifold (including manual adjustable type, hydrauic type and fixed type. in addition, it is available to directly open the
well for gushing through the gate valve when the casing pressure is quite high
4.Choke Manifold Specification
The pressure level of the choke manifold manu factured by Our Company is divided into five levels, namely 14Mpa.21Mpa, 35Mpa. 70Mpa
and 105Mpa. Moreover, it can also be designed according to customer requirements

Working Pressure: 2,000psi to 15,000psi
Nominal Diameter: 2 1/16"- 4 1/16'
