Root cause investigations of failures in heat exchangers that are used in cooling water service often reveal that design conditions were a major contributor to the failure. This paper will review several of the most commonly encountered design problems and show how they inevitably lead to severe corrosion and/or fouling. Examples will be used to illustrate design failures. Guidelines will be suggested on heat exchanger design methods to minimize the potential for future failures.
