大型电站锅炉的汽水分离器体积比较大,壁厚比较厚,采用常规的超声波检测技术耗时多,对缺陷的定性也比较困难。TOFD检验技术具有缺陷检出能力强,缺陷定位精度高、节省设备的制造时间等特点,在检测数据上保证安全,并且可以用数字型式永久保存。T0 FD检验技术原理是利用超声波遇到诸如裂纹 Large-scale power plant boiler water separator larger volume, thicker wall thickness, the use of conventional ultrasonic testing technology takes more time, the qualitative characterization of the defect is also more difficult. TOFD inspection technology with defect detection ability, defect location accuracy, saving equipment manufacturing time and other characteristics of the test data to ensure safety and can be permanently stored with digital type. T0 FD test principle is the use of ultrasound encountered such as cracks
