Corrosion Scanning with Handheld DM Array Probe

Customer Need

Historically, ultrasonic corrosion surveys have been conducted with point measurement probes taking a grid of points over a given area. Unfortunately, this method provides an incomplete picture which makes it likely that the true minimum of a given inspection area is never detected.


Inspection of assets subject to internal corrosion and erosive wall loss such as piping, storage tanks, and other critical assets; requiring visual display and confirmation of remaining wall thickness.

Customer Solution

By using BHGE's handheld DM Array Probe, the suspect area can be 100% scanned to locate the true minimum thicknesses--as well as any random pitting or damage that may exist. This provides a much more accurate assessment.
