Brief of DST tubing string testing valve / TST valve

The tubing string testing /TST valve is used to pressure-test the work string while running in the hole. The valve is operated after it is stung into a permanent packer or a retrievable packer is set. The TST valve requires a differential pressure between the annulus and the tubing to shear. The TST valve can also be used for pip flexing if it is run below an annulus pressure-responsive circulating valve.

 

The TST valve consists of:   

• Flapper valve and spring.

• shear pin section

• locking dogs
