Corrosion under Insulation (CUI) is accelerated corrosion that takes place under insulation typically used to conserve energy, help with process control, and protect workers from temperature extremes. CUI is an issue for facility owners in many industries that use heat or cold in their industrial processes, including chemical processing, refining, fertilizer manufacturing, and power generation. Insulation used in these applications is generally mechanically attached to the substrate vessel or pipeline and is typically covered with cladding. Cladding is typically made out of metal or plastic and is applied to protect the insulation from physical damage and to keep water away from the insulation and substrate.
