讨论采用超声导波检测电站锅炉主汽管道的可行性,选择了合适的导波模式,试验结果表明超声导波检测主汽管道是可行的,可有效检测出深度1.5 mm、宽度0.2 mm的内外表面直槽,并且检测速度大大高于传统的逐点检测。
The feasibility of using ultrasonic guided wave to detect the main steam pipe of power plant boiler was discussed. The suitable guided wave mode was selected. The experimental results show that it is feasible to detect the main steam pipe by ultrasonic guided wave, which can detect the inner and outer depths of 1.5 mm and 0.2 mm Surface straight slot, and the detection speed is much higher than the traditional point-by-point detection.
