Regarding to saving maintenance cost and extending the life of boiler facilities, if the amount of damages can be evaluated quantitatively in the early stage by Nondestructive inspection, the facilities can be operated with lesser repairs. To make this come true, the facilities should be checked, evaluated, and made the quantitative analysis data on the damages like crack etc. in the early stage. Type IV cracks that caused by the creep damages developing on main steam pipe or reheat pipe weld, are difficult to detect and measure a crack depth with usual UT technique, because of the damaged location (subsurface) and its direction (slope). As the third stage of this development of crack measuring technology on steam pipe using the phased array UT technique, we performed measuring and quantitative analysis of actual sample test pieces having type IV cracks.
