Corrosion under insulation (CUI) is corrosion that occurs in the base metal of piping, storage tanks, pressure vessels, and other assets when moisture penetrates the outer insulation. Corrosion and damage to the insulation are difficult to detect without the costly process of removing portions of it and performing an inspection. Standard techniques help identify damage in isolated areas but are resource intensive if prioritizing the overall condition of the asset.

Alternatively, robotics-based NDT techniques, such as Rapid Ultrasonic Gridding (RUG), reveal CUI through an internal inspection without the need for scaffolding or removing insulation. This technique utilizes ultrasonic testing to measure the thickness of the insulated metal. When paired with data visualization tools, the readings are used to generate 2D or 3D corrosion heat maps of the entire asset.
