Acid Corrosion Inhibitor




- Various acids such as hydrochloric acid, sulfuric acid, citric acid, phosphoric acid and sulfamic acid are used to clean scale and rust of the inner parts of equipment such as the boilers for chemical power generation, heat exchangers, chemical plants, etc. for the purpose of maintaining the equipment. The acid corrosion inhibitor is added into the acids with just a small amount during pickling in order to inhibit to the maximum the corrosion of the equipment by the acids.
