corrosion inhibitor
In matrix treatments, a chemical added to acid that adsorbs on the pipe surface to form a protective film. This decreases the destructive reaction of acid with metals. The inhibitor does not completely stop the corrosion reaction, but it eliminates more than 99% of the metal losses that would occur if the inhibitor were not present. The inhibitor has little
Detailed Explanation
or no effect on the reaction rate of acid with limestone, dolomite or acid-soluble minerals.Specific corrosion inhibitors are environmentally compatible, effective in hydrogen sulfide [H2S] environments, effective on high chrome steel, and effective on special steel alloys, such as coiled tubing. These inhibitors may be used at temperatures approaching 500oF [260oC].
