Corrosion Under Insulation


Case Study 8 - CUI

Case Study 8: CUI

Corrosion under insulation (CUI) is a severe form of localized external corrosion which occurs in carbon and low alloy steel pipe that has been insulated. CUI is common in refineries and process plants that typically operate equipment at elevated temperatures and can quickly lead to structural failure which can have catastrophic consequences. GUL's guided wave system can successfully detect CUI in pipes.
