我处自用超声波探伤以来,一直延用我国推荐的机油耦合剂,白山水电站钢管安装后、为了保证钢管外表面与混凝土接触严密,要求彻底清除探伤机油、虽然用了大量劳动力和汽油,也很难清除干净,为了解决上述难点,对化学浆糊粉代替机油探伤耦合剂进行了试验,经过多次试验和白山电站两台机组钢管、蜗壳的实用结果,完全符合耦合剂的四个指标,即。
Since our own use of ultrasonic flaw detection, has been extended with our recommended oil coupling agent, Baishan Hydropower Station steel pipe installation, in order to ensure strict contact with the outer surface of concrete pipe, requiring the complete removal of flaw detection oil, although the use of a large amount of labor and gasoline, it is difficult Clean, in order to solve the above difficulties, chemical pulverized powder instead of oil coupling agent was tested, after several tests and Baishan Power Station two units of steel, volute practical results, in full compliance with the four indicators of coupling agent, namely .
