Overview of Cooling Water Corrosion

Cooling Water (CW) Corrosion and fouling are closely related and should be considered together. Critical factors in controlling both include: process and CW temperatures, heat flus, water velocity, type and quality of water (salt, brackish, fresh), and type of cooling system. When managing heat exchanger bundles, cooling water corrosion control is simply a matter of proper design, continuous maintenance of high quality water treatment, and proper operating practices. Corrosion in CW exchangers can manifest itself as general thinning, pitting, stress corrosion cracking, and microbiologically induced corrosion (MIC).  Metallurgical upgrades may be necessary in some circumstances, especially where fluid velocities cannot be adequately controlled, process or CW temperatures are too high, or water chemistry is not good.
