Choke Manifold & Data Head


Choke Manifold and Data Head are key components in surface test system.                                     


Choke Manifold

  • Used to control flow and pressure during testing

  • Special five-valve module (gate valve)

  • Double-bean design: one (1) positive choke valve with a pressure relief valve on one side and one (1) manual choke valve on the other side. 

  • Full bore and two-way metal seal

  • Choke bean features hard alloy inside, delivering high resistance to erosion and corrosion.


Data Head

  • Installed on upstream and downstream of choke manifold, equipped with pressure ports and temperature ports to connect pressure gauge, pressure sensor and chemical injection device.

  • Easy for pressure and temperature record and monitor.

  • A sampling port is available for fluid sampling.

  • Pressure port can be used to inject chemicals such as anti-freezing agent and anti-foaming agent to prevent hydrate from blocking flow path. 

  • Autoclave is available for pressure above 10,000psi.
