Estimating the term…
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.
A heat exchanger tube cleaner for removing a blockage in a tube, the blocked tube being part of an array of tubes wherein a tube sheet provides access to the tubes through openings in the tube sheet in registry with the tubes, comprising:
A tube cleaner for removing a blockage in a condenser tube, the blocked tube being part of an array of tubes and wherein a tube sheet provides access to the tubes through openings in the tube sheet in registry with the tubes, comprising:
A tube cleaner for removing a blockage in a condenser tube, the blocked tube being part of an array of tubes wherein a tube sheet provides access to the tubes through openings in the tube sheet in registry with the tubes, comprising:
