RD Tubing Tester Flapper Valve / RD TST Valve For Well Testing Service
The Rupture Disc Tubing String Testing valve is a full-opening
tester valve used to pressure-test the drillstem test string while
running in the hole. The RD TST valve is operated after it is stung
into a permanent packer or after a retrievable packer is set. The
TST Valve requires a differential pressure between the annulus and
the tubing to shear. The valve can also be used for pipe flexing if
it is run below an annulus pressure-responsive circulating valve.
The RD Tubing String Tester Valve consists of:
• Ball valve section
• Rupture disc section
• locking dogs
