“After several years of technical and numerous market surveys we have established that there are only two means by which to repair condenser tubes reliably. The first method is to replace the tubes. The alternate method of Shield/Seal repair has proven to be the most effective and technologically sound means of not repairing, but also significantly extending the service life of condensers.” J.J.D’Amato, Commanding Officer NAVSURFLSNT United states navy
