INSPECTION HISTORY OF FOSTER-WHEELER STEAM ACCUMULATORS USED WITH TC13 AND TC13 MOD 1 STEAM CATAPULTS.
Abstract
The various methods used to inspect the steam accumulators were visual, magnetic particle and dye penetrant, radiographic, and ultrasonic. All cracks 1/4 in. or less in depth were ground out and faired; cracks greater than 1/4 in. in depth were repaired by grinding, welding, and stress relieving. Almost all defects foundd during the inspections of the steam accumulators were in the circumferential welds and large nozzle forgings to shell welds, which are areas of high stress concentration and appear to be most affected by rapid and large changes in steam conditions. Grinding, welding, and stress relieving of cracks in the steam accumulators proved to be an acceptable repair practice, and aided in prolonging accumulator service life.
