Corrosion Under Insulation

Corrosion Under Insulation (CUI) is a severe form of localized external corrosion that occurs in carbon and low alloy steel equipment that operates at temperatures between -4°C and 175°C. CUI occurs at the interface of the external surface of the equipment and the insulation medium used to conserve energy or protect personnel.
