ABSTRACT

Corrosion is both costly and dangerous. Billions of dollars are spent annually

for the replacement of corroded structures, machinery, and components,

including metal roofing, condenser tubes, pipelines, and many other items.

In addition to replacement costs are those associated with maintenance to

prevent corrosion, inspections, and the upkeep of cathodically protected

structures and pipelines. Indirect costs of corrosion result from shutdown,

loss of efficiency, and product contamination or loss.
