Comparison of Corrosion Mapping Solutions using Phased Array and Conventional UT Techniques

There are many kinds of corrosion inspection solutions and choosing the right one may be complex.

Comparison of Corrosion Mapping Solutions

Corrosion mapping by ultrasonic testing has been proven by many industries for numerous years. Specific Inspection Fields using this application are pressure tanks and clad vessels. The solution depends on the customers’ requirements and this paper will show how Sonatest can provide them.

UT Corrosion mapping is a quantitative way to inspect the thickness of a material affected by corrosion. Oxidation or erosion reduces piece thickness and pulse-echoes distances are directly reduced.
