Various surroundings factor damages boiler tube. We must inspect tubes and find the damage which lead to hazard before hazard happened. In boiler tube, the most typical damage is thickness reduction. We show Inner Ultrasonic Testing method with examples of inspecting thickness reduction for boiler tube. We developed the probe which have multi-channel and can inspect cross section of tube at one time. Inner Ultrasonic Testing method is that we apply Ultrasonic Testing for boiler tube by the probe in boiler t...
