• Drilling Chokes

    Fluids can be circulated from the well bore while holding any desired back pressure rating of the choke. The system includes one or two hydraulically operated chokes, pressure transmitters for drill pipe and annulus pressures, and a floor-mounted control panel.

    Features/Benefits

    Available at Different Working Pressures:

    Chokes are available for working pressures of 5,000, 10,000, and 15,000 psi. They will operate at temperatures up to 300 F and are suitable for H2S service. Choke plug, seat and downstream inner sleeve are designed for long life, even under extreme operating conditions.

    Downstream inner sleeve:

    Downstream inner sleeve, plug and seat are all manufactured from sintered tungsten carbide - an extremely hard, fine grained material - for maximum wear resistance.

    Threaded Bonnet:

    Threaded bonnet makes maintenance simple. It is possible to change all components in a very short time without removing the choke from the manifold.

    Conveniently Arranged Control Panel:

    Conveniently arranged control panel allows operation of one or two chokes and monitoring of important well-killing data from any desired remote location. The control system is designed to operate the choke quickly and reliably in response to changing conditions in the well bore.

    Panel is Compatible with any Rig Design:

    Panel is compatible with any rig design with hydraulic power to the chokes available from an air operated pump with a manual hydraulic pump for back up.
