SubCHECKER PT Test Stand
Off-line High Pressure Testing of Drill String Well Control Valves
The Sudelac SubCHECKER™ PT is a versatile pressure testing stand to pre-use test many types and sizes of drill-string pressure control subs, (Safety Valves, IBOP’s, Gray Valves, Kelly Cocks etc.). The SubCHECKER™ PT Test Stand allows safe and efficient off-line high pressure testing of subs to take place saving valuable rig time and providing pre-use assurance of drill-string components. Importantly no high torque make-up is necessary and only a chain-tong or strap wrench is required to make-up and break-out the subs being tested.
The SubCHECKER™ PT is self-contained, free-standing, portable and should be used in a designated area suitable for high pressure testing. The operator can connect suitable high-pressure iron (chicksans) directly to the stand from a permanent high-pressure pumping unit or a flexible HP hose and air operated pressure testing pump skid. Each different size and type of drill string connection on well control valves is accommodated by a dedicated Adapter Sub. The Adapter Subs are usually box up to accept the pin on the valves, but pin up Adapter Subs for IBOP’s can also be provided.
The SubCHECKER™ PT is easy to use and maintain with only low cost consumables being required. The stand is suitable to use on Offshore or Onshore Rigs, in maintenance workshops or remote locations to support nearby rig operations.
Pressure test the closed or shut-off feature of the sub with the stand and with the addition of a test cap the integrity of the whole sub mandrel or housing can also be assured.
