Research on High-Frequency Ultrasonic Guided Waves In-service inspection of Tank Bottom

  • 摘要: 石油、天然气等化工行业中,储罐经过长时间运行后,储罐的底板会出现不同程度的腐蚀变薄甚至穿孔,严重危害生产安全。采用S0模态的高频超声导波对模拟储罐边缘板人工试块进行检测,得出不同条件对高频导波检测能力的影响。在实际检测中,成功采用高频导波对储罐边缘进行快速大面积在役检测并发现储罐边缘板的腐蚀缺陷。通过人工试块对比试验和现场在役检测,验证了高频导波对储罐边缘板腐蚀检测的可行性。
    Abstract: In the oil, gas and other chemical industries, different degree of damages, such as corrosion, thinning and even perforation often appears on the tank bottom after a long time operation, which affects the safety of production. The artificial blocks simulating the tank edge were inspected by using high-frequency ultrasonic guided waves of mode S0, and influences on testing capacities of high-frequency ultrasonic guided waves in the different conditions were obtained. Based on the experiment, the tank edge plate was detected successfully by means of the large area and in-service rapid inspection, and the tank corrosion defects at the edge of the plate were found. Through artificial blocks contrast experiment and in-service inspection, it is concluded that the corrosion testing of tank edge floor by high-frequency guided waves is feasible.
