Abstract

Ultrasonic guided waves in pipes have been used as a powerful and effective tool for long-range inspection of pipes as they have the potential of propagating long distances with little attenuation. The propagation phenomena of guided waves in straight pipes have been investigated by many researchers; however, the propagation of guided waves across features such as bends in the pipe network is still not well understood. In order to study the complicated characteristics of guided waves propagating in multi-bends pipe, experiment on detecting multi-bends pipe using guided wave was conducted based on magnetostrictive sensors. Guided wave properties such as propagation speed, mode conversion, energy attenuation were studied in experiment. The result showed as follows: guided waves’ propagation speed in multi-bends pipe with slight bend curvature was similar to the one in straight pipe; the bend lead to mode conversion obviously; the energy of guided waves attenuated exponentially along with the propagation time and the attenuation rule was closely associated with excitation frequency. This study would provide reference for the guided waves application in complex pipes with bends.
