Boiler Corrosion Inhibitors | ChemTreat Inc.

In the presence of oxygen and water boiler system corrosion occurs as metals attempt to revert to their natural state (such as iron oxide Fe 2 O 3 or Fe 3 O 4). Other problems include corrosion beneath deposits and in mechanically-stressed areas and corrosion caused by the presence of carbon dioxide dissolved in water (condensate).
