Abstract

Abstract: To get the relationship between the defects and ultrasonic guided wave, the dispersion characteristic of guided wave in pipe was studied. Then the finite element model of a pipe with a through-type defect was established. Taking the axial and circumferential defects with different sizes as research objects, the relationship between the defect location and defect size with the ultrasonic guided wave reflection coefficients was studied, using a control variable method, by finite element simulation. The results show that there is a linear relationship between the circumferential sizes of the defect and the reflection coefficients for through-type defects when the L (0,2) and T (0,1) guided wave are used, and the axial position and circumferential size of the detect can be detected respectively by the defect echo position and amplitude values. The study provides a reference for sizing and locating of detects in pipe.
