Boiler Alkalinity Chemical

Boiler Alkalinity Boiler Alkalinity chemicals are used to increase the boiler water pH within the boiler water. The mild steel boiler tubes prefer higher pH waters. Increasing the boiler pH may reduce corrosion rates, allow the polymer to activate, and minimize silica scaling. ChemWorld stocks 25% and 50% of alkalinity solutions.
