Corrosion Under Insulation: CUI Testing and Inspections
ATS experts conduct corrosion under insulation (CUI) testing and inspections. Corrosion under insulation is a type of metal corrosion that occurs due to moisture and oxygen exposure. Breaks in jacketing or insulation can allow water to seep into an insulation system via rain, condensation, or spillage. If the insulation absorbs the water, or the water collects underneath it and cannot escape the system, CUI can occur. CUI affects carbon steel as general or localized corrosion; even stainless steel can experience localized corrosion or stress corrosion cracking. Left unaddressed, CUI can cause leaks, equipment failure, and unexpected downtime. ATS performs CUI testing and inspections to help clients minimize these potential issues.
