Corrosion Under Insulation (CUI) is a common yet often concealed threat to industrial infrastructure, leading to the deterioration of steel components and costly repairs. When moisture becomes trapped beneath insulation—especially in environments exposed to temperature changes, humidity, or harsh conditions—corrosion can occur if the steel lacks adequate protective coatings or is not properly sealed with weather-resistant cladding.


Without the correct preventative measures, CUI can severely impact the lifespan and safety of plant equipment. Early detection and effective remediation are critical to avoiding unexpected shutdowns and high maintenance costs.
