Reliable 10,000-psi choke for pressure control during transition operations
The advanced 10K SUPER CHOKE is one of the industry’s most widely used pressure control innovations. It delivers easy and precise well pressure control during transition operations, such as mud pump start-up or shut-down. The 10K SUPER CHOKE is equally effective when mud and gas are flowing alternately through the choke. It is designed and manufactured for hydrogen sulfide service and abrasive fluid applications.
The 10K SUPER CHOKE regulates pressure automatically under all conditions. Choke operators no longer have to fight the controls
Three methods of operation:
-
Normal operations – Activation is rig air-operated.
-
If rig air is lost – Activation is manual with hydraulic pump located on remote control skid.
-
If hydraulic lines are severed – Activation is manual with bar provided on indicator head.
Features and Benefits
-
Built to Handle the Pressure – The 10,000-psi drilling choke (10K SUPER CHOKE) is precision engineered for precise well control under harsh and demanding conditions.
-
Unique Choke Plate Design – Heavy duty diamond lapped tungsten carbide plates are honed to a flatness measured by light bands and feature unique half-moon shaped orifices. Rotation of the actuator fork allows finite regulation of the size of the opening from full open to full close.
-
Positive Closure – A 17°-dead band overlap beyond the full close position is designed to ensure closure even if the plates become worn following extended exposure to abrasive laden fluid flow. Pressure drops or surges will not affect the quality of the seal in the plate-to-plate design. In fact, the seal improves under pressure.
-
Tungsten Carbide Wear Sleeves – Tungsten carbide wear sleeves increase in-service life. Extended wear sleeves are available to absorb the effects of abrasive downstream turbulence especially during underbalanced drilling operations.
-
Versatile – Ideal for onshore and offshore applications. Controls can be from either remote or on-site consoles.
