GripTight^® Reverse Pressure Test Plug

Pressure test flange-to-pipe welds with full radial, hoop and axial stresses – equivalent to the stresses that would be produced when using a blind to pressurize the entire piping system. Pressure testing can effectively verify the weld integrity providing the user confidence that the flange and weld will properly function when placed into service.

Test Pressure
2250 PsiG (155 BarG)*

Size Range
2” to 12” NPS (DN50 to DN300)
Larger sizes available upon request

Standard Seal Material
Urethane**

Features

• Subjects the flange-to-pipe weld to full radial, hoop and axial stresses during hydrostatic testing

• Flange-to-pipe welds can be tested without needing to pressurize the entire system

• Optional lanyard assembly acts as visual plug movement indicator allowing the operator to monitor the plug position during testing and halt work if improper installation occurred

• ASME PCC-2 Type IV testing device1
