Corrosion Under Insulation Course and 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.

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

Who should attend

The course was designed to be applicable for anyone working within an industry affected by CUI. Job titles may include but are not limited to:

  • Specifiers and Designers
  • Metals, Coatings and Risk Based Inspectors
  • Coating Contractors
  • Maintenance personnel and project engineers
  • Manufacturers of insulation materials and equipment
  • Unit managers involved in CUI
