CUI is localized external corrosion of carbon steel or stress corrosion cracking of austenitic stainless steel caused by trapped moisture under insulation. It is most common in service temperatures between -4°C and 175°C (25°F to 350°F). The insulation wicks water, chlorides leach out, and the metal corrodes invisibly. Inspection requires stripping insulation at random "bell hole" locations or using real-time radiography. The Expectation: Design thickness calculations
