管道缺陷的超声导波检测研究
|
摘要
针对管道缺陷与超声导波交互的特点,为解决在管道超声导波检测中的缺陷定位困难、轴向尺寸无法量化等繁琐和耗时严重等问题,设计了自发自收和一发一收两种管道缺陷的超声导波检测平台,对特定环形缺陷进行管道超声导波检测进行了研究,探究了环形缺陷的轴向长度和径向深度对超声导波检测的影响。结果表明:采用自设计的超声导波检测平台可实现管道缺陷的定位检测及轴向尺寸定量检测,缺陷的轴向长度主要影响缺陷回波的形态,缺陷的径向深度主要影响回波的能量。
According to the characteristics of the interaction between pipeline defects and ultrasonic guided waves, two detection platforms of self-excitation and receipt and pitch-catch are designed to solve the severe problem of location and axial dimension assessment in ultrasonic guided wave testing. The experiment was carried out to explore the influence of axial length and radial depth of annular defects on ultrasonic guided wave detection. The results show that the self-designed ultrasonic guided wave detection platform can be used to detect the location and axial dimension of pipeline defects. The axial length of defects mainly affects the form of flaw echo, and the radial depth of defects mainly affects the energy of echo.
