Corrosion under insulation: a rewiew

Corrosion under insulation (CUI) occurs from electrochemical reactions on the surface of thermally insulated industrial equipment and has water as an electrolyte. CUI generates many costs for companies due to maintenance can also cause problems human environmental integrity. In this work, vast bibliographic research was carried out corrosion insulation, in articles published between 1998 2022, with objective evaluating Industry, factors that influence it, mechanism, non-destructive inspection techniques work a mitigation problem. As result, it confirmed is serious problem industry, especially petrochemical one, its detection not so simple expensive when done visually. To solve difficulty identification detection, tests are used, through various technologies, possible prevent being damaged and, some cases, be without stopping process. addition, situations generated non-monitoring CUI, such as: Economic, integrity impacts.
