Corrosion Under Insulation (CUI)

When the integrity of an insulation is compromised, moisture penetrates and is trapped. This, along with the high temperatures and contaminants present, creates a highly corrosive environment that is not immediately visible.

Corrosion Mechanism Under Insulation (CUI)

Damage caused by corrosion under insulation (CUI) is a common and ongoing threat to the integrity of assets in industrial facilities. Some of the consequences are: prolonged downtime, high maintenance costs, equipment failure, and even catastrophic leaks or explosions.
