n recent years, the quality of the circulated water in evaporative condensers and cooling towers has declined as air and water pollution has increased. As regulations limit the use of many corrosion inhibitors for the hot dip galvanizing process, such as chromates, the passivation process for protection has become even more critical. Passivation is a […]
