Corrosion Under Insulation (CUI) inspection plays a vital role in maintaining the structural integrity and longevity of insulated piping systems and industrial assets. Over time, trapped moisture beneath insulation layers can lead to hidden corrosion, weakening metal surfaces and compromising safety. Through specialized CUI inspection techniques such as ultrasonic testing, visual assessment, and thermal imaging, industries can detect early signs of deterioration before costly failures occur. This process is essential across sectors like oil and gas, petrochemical, power, and marine, ensuring operational safety, reduced downtime, and extended equipment life through proactive maintenance and timely intervention.
