Inflatable shutter THPGV

for pipesrubber

THPGV inflatable pipe stoppers are used within the primary zone of nuclear facilities. These systems are designed to plug steam generator man-holes during maintenance operations or if leaks are present in the steam generator’s water boxes. It becomes essential to rapidly plug the man-holes. Indeed, they have remained open in the event that leaks are identified on the stopper or if the primary pipeline’s drains have ruptured. Moreover, Our THPGV inflatable pipe stoppers have been studied and developed in close collaboration with EDF. They are the perfect solution to these problem scenarios. Finally, several diameters of stopper are available based on the diameter of the manhole: 900mW, 1300 mW and EPR.
