Corrosion Under Insulation: The Hidden Threat!

CUI is currently the subject of increased focus for the industrial process industries. Corrosion Under Insulation Masterclass (CUI) refers to the external corrosion of piping (corrosion of metals)and vessels that occurs underneath externally clad/jacketed insulation as a result of the penetration of water. By its very nature CUI tends to remain undetected until the insulation and cladding/jacketing is removed to allow inspection or when leaks occur. CUI annual global control spend is estimated as €2 billion yet there continue to be CUI failures, many of which are significant in terms of safety, cost and reputation
