The common alloys used for tubing in power plant feedwater heaters and condensers are identified and the major corrosion problems encountered in these components are described. The frequency of failure and failure modes in both components are shown to be alloy specific. Some corrosion problems are shown to be controllable through minor design modifications in the equipment and others through judicious selection of alloys. In condensers, alloy selection is most effective when based on tube location. In feedwater heaters, strict control of water quality is shown to be necessary with most alloys to minimize corrosion problems. Benefits of some auxiliary techniques for preventing corrosion attack include coating and cathodic protection of the tube sheet and cooling water intake screens.
