Abstract
A method for measuring pipeline corrosion includes: obtaining a material property of a to-be-detected pipeline, and calculating a theoretical dispersion curve of the to-be-detected pipeline based on the material property; determining a theoretical frequency-thickness product and a theoretical frequency of a zero-group-velocity (ZGV) Lamb wave mode from the theoretical dispersion curve; obtaining a target excitation signal corresponding to the theoretical frequency; sending the target excitation signal to the to-be-detected pipeline and receiving a target waveform, where the target waveform is obtained by reflecting the target excitation signal through the to-be-detected pipeline; determining an actual frequency of the ZGV Lamb wave mode from the target waveform; and calculating corrosion of the to-be-detected pipeline based on the theoretical frequency-thickness product and the actual frequency of the ZGV Lamb wave mode.
