Corrosion is a persistent issue in various facilities, affecting productivity. Corrosion under insulation (CUI) is prevalent in industries like oil and gas, causing hidden damage, reducing equipment efficiency, and posing environmental and safety risks. CUI is hard to detect, leading to increased maintenance costs and potential safety hazards like leaks or explosions. Preventative measures include using appropriate insulation materials, proper installation, regular inspections, and employing corrosion inhibitors to mitigate the environmental impact and ensure safety. The Piper Alpha incident in 1988 highlights the severe consequences of corrosion-related explosions.
