The choke manifold is flow control device used in well testing for reduction and/or control of flow pressure. The choke manifold consists of gate valves, high-pressure fittings, chokes, pressure gauge, connections and skid. The choke manifold is designed based on the operator’s condition, but usually designed as 4- or 5-valve assembly. Chokes, either adjustable or fixed, are used to achieve desired flow rate during testing.

Chokes are the pressure and flow reduction valves, either adjustable or positive used in the choke manifold, as well as other oilfield equipment, such as x-mas tree, line heaters.
