Ultrasonic Corrosion Mapping, Computerised

Ultrasonic corrosion mapping techniques are widely used in industry for the in-service detection and characterisation of corrosion in pipes and vessels. The data acquired for scanning is processed in real time and C-Scan view of the material (plate or pipe) being inspected develops on the computer screen as the scanning proceeds. C-Scan gives the image of the flaws in the material on the plan view, i.e., as seen from the direction of scanning. This view gives changes in thickness of the material due to far side corrosion, and also planar defects parallel to the entry surface. The discontinuities detected are: laminations, lamellar tears and hydrogen induced cracking.
