Product Description
Lift type Choke manifold
Choke manifold is a necessary device for controlling well kick and implementing oil-gas well pressure control. When blowout preventer is closed, choke valve can be turned on and off to control certain casing pressures to keep bottom hole pressure a little higher than formation pressure all the time, lest formation fluid should further flow into well. Besides, when well is shut off, choke manifold can be relieved for the realization of soft shut-in. When the pressure rises to a certain level, it can be used to open the well for gushing so as to protect the well.

Choke manifold is composed of choke valve, gate valve, pipeline, pipe fittings and pressure gage, etc.
When well pressure rises, the choke valve (it falls into three kinds: Manually adjustable, hydraulic and positive) on choke manifold can be turned on and off to release the fluid to control casing pressure. Gate valve can be used for direct blowout. When casing pressure is pretty high,

The pressure class of our company's chokes manifold falls into five class: 14MPa, 21MPa, 35MPa, 70MPa and 105MPa. Also, we can design according to customer demand.
