Cooling Systems and equipment that are not properly cleaned and passivated prior to entering service will experience corrosion problems that are difficult to overcome once the system is placed in operation. This paper reports on recent developments in cleaning and passivation chemistry that are applicable to new cooling systems and to older systems requiring rust removal and passivation. Laboratory electrochemical results will be presented as well as plant application case histories.
