[0002] With the continuous development of industrial facilities and the increasing complexity of pipeline systems, the safety and reliability of pressure pipelines have become a critical concern. Over long periods of use, pipeline materials may change due to factors such as corrosion, fatigue, and wear, affecting the pipeline's mechanical properties and operational safety. Therefore, how to efficiently and accurately assess the damage status of pipelines has become a key problem that urgently needs to be solved in the field of pipeline inspection.

[0003] Ultrasonic thickness measurement is an essential stage in pipeline inspection. However, this method requires knowledge of the sound velocity of the pipeline material. In some cases, the material of the pipeline may be unknown, which necessitates material analysis methods to obtain the current material parameters of the pipeline.

Furthermore, these methods have limitations in assessing the material uniformity of the pipe's internal and external surfaces. In recent years, ultrasonic testing technology, as a non-destructive testing method, has gained widespread attention due to its ability to evaluate the internal structure and material properties of the workpiece without damaging it.
