Fully-Automated Corrosion Mapping

Fully-automated corrosion mapping is a conventional ultrasonic thickness method used to map a materials thickness. The transducer is fixed in a rastering probe holder that travels a fixed distance such as the circumference of a pipe or pressure vessel. Thickness measurements are made at a pre-set resolution such as 3mm x 3mm depending on the application and essentially replaces the manual UT thickness “1 inch grid” survey. Variations in material thickness due to corrosion, abrasion or erosion are then graphically displayed as a 2D or 3D image. Additionally, all thickness measurements can be exported to excel spreadsheet where statistical analysis of results can be made.
