Save Time & Money - Eliminate Costly Pre-Heat & Post-Weld Heat Treatment
Conventional methodology for pressure testing plain/bevel end pipe spools requires welding on end caps,
performing the pressure test, then cutting off the end cap and re-beveling the pipe. Employing test plugs in lieu
of welding end caps eliminates this time consuming cycle, as well as pre-heat and post-weld stress on the heat
affected zone (HAZ) at the spool’s end.
GripTight MAX® - Stats & Features
GripTight MAX Test Plug is a revolutionary plug designed to significantly improve project schedules and increase
the range of pipe materials and pressures that can be safely tested.
