Features of Tubing String Tester Valve

 

* The flapper valve required only need 4psi to be openned .

* The testing string can be pressure-tested many times .

* Valve shear rating can be pre-determined at 500psi increments.

* The tubing tester Valve can also be used for pipe flexing.

 

Operation of the TST Valve

 

When the tubing string testing valve run in the hole, flapper valve keeps open, it allows the workstring to fill up. The shear pins hold the mandrel in place. The workstring can be pressure-tested as many times as required when the tubing string tester valve is run in the well.
