Recently we discussed the basics of corrosion under insulation. CUI is a blanket term that refers to several different types of corrosion processes. Based on how a part is used and what conditions it’s exposed to, the kind of corrosion that develops may differ.

Corrosion under insulation (CUI) is a severe form of localized external corrosion that occurs in carbon and low alloy steel equipment that has been insulated.
CUI itself is most commonly galvanic, chloride, acidic or alkaline corrosion. If undetected, the results can lead to leaks and the shutdown of a process unit or an entire facility, causing a war against corrosion!
