  • System for plugging heat exchanging tubes
    Patent number: 8863387
    Abstract: 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.
    Type: Grant

  • HEAT EXCHANGER TUBE CLEANING APPARATUS AND METHOD OF REMOVING A BLOCKAGE FROM A TUBE
    Publication number: 20120175078
    Abstract: A cleaning apparatus for removing a blockage from a heat exchanger tube of a steam generator, or the like, having a plurality of tubes extending between a pair of tube sheets. Anchor plate fasteners, which are expandable inside tubes adjacent to the blocked tube, are used to mount an anchor plate to one of the tube sheets. The anchor plate has an opening for aligning in registry with the condenser tube having the blockage and provides a solid platform for mounting either a mechanical device or a fluid pressure device for providing a force against the blockage for removal of the blockage. The cleaning apparatus enables a force to be applied which is significantly greater than that which can be applied with known hand-held devices for removing blockages.
