Abstract
Nondestructive testing has been used by the Canadian Forces to establish the durability of Naval boilers, an evaluation that has traditionally been performed by destructive sectioning and gaging of boiler tubes. Metallurgical analysis of wasted and failed marine boiler tubes has shown that numerous wastage mechanisms are operative: overheating and external oxidation, external corrosion, internal pitting corrosion, stress-corrosion cracking and corrosion-fatigue cracking. Those wastage mechanisms which are expected to result in failures can be and are being monitored by nondestructive testing; namely, immersion ultrasonic gaging, radiography, and visual inspection techniques.
