Nondestructive Detection of Pipeline Based on Ultrasonic Guided Wave Technology

  • 摘要: 介绍了磁致伸缩超声导波检测方法的原理,通过对长输管道的建模分析,得到长输管道的导波传输特性.针对试验室样管与现场管道进行导波数据实测,检测表明:磁致伸缩超声导波无损检测技术应用于长输管道的检测中,可以提高检测效率并能达到截面变化量1%以上的检测灵敏度,给长输管道的长期稳定运行提供了较有力的技术保障.
    Abstract: The theoretical basis of magnetostrictive ultrasonic guided wave inspection was introduced.The transmission characteristics of guided wave in long range pipeline were obtained by building up modal analysis of the pipeline.Experimental tests were carried out for laboratory pipeline and field pipeline,respectively,and results showed that inspection by using the magnetostrictive ultrasonic guided wave could greatly enhance the testing efficiency for the long range pipelines and it could reach the sensitivity of detecting variation in cross section change of less than 1%.Current method of magnetostrictive ultrasonic guided wave inspection could provide strong support for the safe running of the pipelines.
