Abstract
Nondestructive evaluation techniques have been used extensively in naval boilers to establish wastage in superheater, economizer and generator tubes. Ultrasonic gauging and radiography have proven most effective. The paper describes a semiautomatic immersion ultrasonic system which has been developed for the evaluation of generator tube corrosion above the mud drum and of superheater tube thinning by external oxidation. The unit utilizes microprocessor-based electronics and refined ultrasonic probes.
