Cooling water system corrosion causes immediate and delayed problems.

Difficulties spread from a failure like ripples from a pebble thrown into a pool. A single failure may force an unscheduled outage, redirect worker efforts, contaminate product, compromise safety, increase equipment expense, violate pollution regulations, and decrease productivity.

The closer one is to the failure, the more its direct effects are apparent. The cumulative effects of failure are often overlooked in the rush to “fix” the immediate problem. Too often, the cause of failure is ignored or forgotten because of time constraints or indifference. The  failure or corrosion is considered “just a cost of doing business.” Inevitably, such problems become chronic; associated costs, tribulations, and delays become ingrained. Problems persist until cost or concern overwhelm corporate inertia. A temporary solution is no longer acceptable; the correct solution is to identify and eliminate the failure.

Preventative costs are almost always a small fraction of those associated with neglect.

The solution to any cooling water system failure begins with a thorough understanding of the cause. Careful, meticulous investigation will almost always reveal the failure source and any attendant accelerating factors. Ideally, potential problems will be identified before failure. The identification of cooling water system potential problems begins with a knowledge of how to recognize such problems. Knowing where particular forms of damage might occur, what damage looks like, how critical factors influence damage, and, most importantly, how such problems can be eliminated are the objectives of this book.

This book follows the format used in The Nalco Guide to Boiler Failure Analysis, also authored by Robert D. Port and Harvey M. Herro, copyright 1991 by McGraw-Hill, Inc. Each chapter is divided into eight sections, giving specific information on damage:

General Description

Locations

Critical Factors

Identification

Elimination

Cautions

Related Problems

Case Histories
