Abstract : An experimental investigation was conducted to determine whether the present practice of solder-wiping the interior of monel water boxes is actually necessary when they are assembled with copper-nickel condenser tubes and tube sheets. Tests of four model condensers were conducted with natural sea-water circulation for a period of 26 months. In addition, corrosion data were obtained in relatively short duration tests of galvanic couples. The tests have demonstrated the continued need for solder-wiping, as well as for provision of zinc anodes, to achieve maximum protection against galvanic attack of tubes and tube sheets. (Author)
