ABSTRACT:
Corrosion damage to the tubes of power plant boiler waterwalls is detected by a portable hand-held ultrasonic scanner probe equipped with plurality of dual element transducers having concave cylindrically curved surfaces for simultaneously examining arcuate areas of walls of several tubes as the probe is moved along the waterwall. Tube wall thickness and probe location data are processed by a computer for detection, display and recording of places where significant tube damage has occurred.
