Corrosion Nondestructive Evaluation (NDE) in Confined Access Areas

NDE corrosion monitoring of steel vessels, tanks, walls, and pipes involve steel thickness measurements, often with hand-held ultrasonic instruments that require the application of a couplant material, that isslow and labor intensive.For this confined space application,IEM proposes a Rapid Corrosion Inspector (RCI) that uses EMAT sensor technology with a build in machine vision camera system to automatically classify corrosion types and map with position and wall thickness.EMAT sensors do not require couplant application and can cover large wall areas rapidly.The sensor/vision system will be designed into a rolling ergonomic assembly that allows users to scan the walls at high speed with one hand.
