There are several methods for non-intrusive corrosion detection. Most give average or spot thickness measurements. Corrosion mapping provides precise measurement and a virtual picture of the damage. UT corrosion mapping can produce precise, repeatable images displaying corrosion damage in top and sectional views.

Images are analysed dynamically to determine pit diameter, depth and distribution. Repeated surveys allow comparison of images and thickness data to determine corrosion rate

Advantage

Precise measurement and monitoring of corrosion damage.
Easily understood images of damage including top and sectional views.
Mechanical scanner makes scans highly repeatable and suitable for long-term monitoring and corrosion rate determination.
