SYSTEM FOR PLUGGING HEAT EXCHANGING TUBES

摘要

A system and a method for plugging a heat exchanger tube or the like. The system includes a plug member having a central shaft having a compressible member mounted on the central shaft such that axial compression of the compressible member radially expands the compressible member into sealing engagement with an inner wall of a tube in which the plug member is inserted. The system further includes a drive means removably engaged with the plug member for inserting the plug member into the tube and for providing axial force on the compressible member to cause radial expansion of the compressible member into sealing engagement with the inner wall of the tube.
