Corrosion Control in Cooling Water Systems

Corrosion control in cooling water systems involves good design and materials selection, as well as good fabrication, installation and operation. Complete corrosion prevention by materials selection 

Substitution of carbon or low-aUoy steels in cooling water systems for those of more expensive materials results in marked savings in initial costs. Use of cheap materials can increase the costs of operation, including water treatment and inhibitor application. A compromise between the cost of construction, materials, and operation should be performed at the design stage. 

The principal economic advantages for the treatment of cooling water system come from two sources  

It reduces frequency of maintenance and inspection shut-downs. 

It permits more extensive use of iron and carbon or low-aUoy steel instead of high-alloy steel and
