94-10: Pitting Corrosion of Cooling Water Systems FillsOperation of cooling water systems requires that availability of system components be optimized. Pitting corrosion of pumps, valves, heat exchangers, piping, etc. impacts this availability. Pitting due to crevices, microbiological activity, deposit is, materials selection, system operation and other variables is discussed. Prevention and control guidelines for pitting corrosion in cooling water systems based upon real system experience are presented.
The thermodynamics and surface phenomena associated with the water chemistry in scale formation will be delineated
Operational causes of system failure may include: (1) improper commissioning
Evaluations of biocide treatment programs are made by monitoring the microbial cells (algal
Pultruded profiles dominate the cooling tower market as the material of choice for field erected cooling towers
Precise knowledge of the heat transfer and pressure drops both on the steam side and airside
presents a special challenge because of the variability in makeup water sources
To reduce energy consumption nearer to design at other than design wet-bulb conditions
these metals suffer from corrosion in acidic-to-neutral and highly halogenated environments that are common in cooling water systems
development of calcium phosphate deposits
the maximum adsorption can be obtained
Amorphous silica alone
