摘要: 介绍了超声导波检测技术的理论基础,指出了这一技术用于在线监测的原理。利用该技术对炼油厂催化装置7条高温管道的腐蚀状况实施了在线监测,举例03-13管线三次监测情况及其数据的对比分析,得出基于磁致伸缩效应的超声导波技术可以实现高温管道腐蚀的在线监测。此外,还指出目前管道超声导波监测技术应用中存在的问题并提出了展望。Abstract: The theory of ultrasound guided wave detection and the principle of using guided wave on on-line monitoring were introduced. At the same time, we made use of the guided wave on 7 high temperature pipes in catalytic cracking unit, and took pipe 03-13 as an example to monitor its corrosion and analyze the data. Finally, conclusions were drawn that the magnetostrictive effect based guided wave technology allowed the monitoring of high temperature corrosion of pipe-line. In addition, the paper pointed out problems faced by ultrasonic guided wave monitoring technology and overviewed its future development.
