Corrosion Under Insulation (CUI) Micro-Credential

Corrosion Under Insulation Micro Credential

Corrosion Under Insulation (CUI) Micro-Credential

Corrosion under insulation (CUI) is a severe form of localized, external corrosion that most commonly occurs on insulated carbon and low alloy steel and stainless steel equipment that operate at high temperatures at or below 175°F.

CUI is most prevalent in the chemical/petrochemical, refining, offshore, and marine/maritime industries. If left undetected, CUI can result in catastrophic leaks or explosions, equipment failure, prolonged downtime due to repair or replacement, and safety and environmental concerns.

Attaining the micro-credential demonstrates competency to prevent corrosion under insulation in refineries, chemical plants, utilities, and other facilities. Identification of CUI can prevent metal loss and expensive maintenance projects.

The course introduces the theoretical and practical aspects of preventing, managing, and inspecting CUI.
