Preventing Corrosion in Liquid Cooling Systems

A suitable corrosion inhibitor must be used with deionized or demineralized water. There are different inhibitors for use with different metals, each with its advantages and disadvantages. Phosphate is an effective corrosion inhibitor for iron, steel, lead/tin solder, and most aluminum components. It is also a very good buffer for pH control.Preventing Contamination and Corrosion in When aerated water is introduced at startup, corrosion of components takes place, thereby harming the boiler system. Many demineralized water storage tanks are dosed with ammonia and hydrazine to reduce the oxygen content. These mitigation practices, however, increase by about 10 times the concentration of carbonate due to the formation of ammonium carbonate.Oxidation Behavior of Carbon Steel Effect of Formation Demineralized Water Corrosion on Carbon Steel Oct 25, 2017The nature of surface oxide formed on carbon steel piping used in nuclear power plants affects flow-accelerated corrosion.
