  • Water Handbook - Preboiler & Industrial Boiler Corrosion

    Low makeup or feedwater pH can cause serious acid attack on metal surfaces in the preboiler and boiler system. Even if the original makeup or feedwater pH is not low, feedwater can become acidic from contamination of the system. Common causes include the following: improper operation or control of demineralizer cation unitsLearn More

  • pH Treatment | CleanBoiler.org

    It ranges from 0 to 14. A pH of 7 is neutral. A pH less than 7 is acidic, and a pH greater than 7 is basic (alkaline). Each whole pH value below 7 is ten times more acidic than the next higher value. For example, a pH of 4 is ten times more acidic than a pH of 5 and 100 times (10 times 10) more acidic than a pH of 6.Learn More

  • Common Steam Boiler Problems & How to Troubleshoot …

    Acid damage: When the pH of the water is too low, the water is acidic. Without neutralizing the acid, it will cause overall thinning of the metal inside a boiler. Caustic corrosion: At the other end of the pH spectrum is damage caused by water that is too basic or has too high of a pH. Typically, this type of damage occurs under scale deposits where the water can boil.Learn More
