Abstract

In order to study the propagation characteristics of ultrasonic guided waves in power plant boiler pipes and the ability to detect defects, the motion equation and dispersion equation of pipe guided waves were derived and analyzed; Numerical simulation study on the propagation process of T (0,1) mode guided waves in power plant boiler bends using finite element software. The results indicate that the longitudinal mode is more sensitive to circumferential defects, while the torsional mode is more sensitive to axial defects. When the T (0,1) mode ultrasonic guided wave propagates in a U-shaped bend, the mode of the guided wave will change.
