Abstract: To overcome the limitations of conventional multi-mode total focused method (M-TFM) in circumferential ultrasonic inspection of thin-walled pipes, this study proposes a circumferential shear-wave multi-mode total focused method (CSM-TFM). Based on M-TFM, analytical expressions for direct, full-skip, and half-skip wave paths and their corresponding time delays in a double-layer medium are derived by the geometric relationships of shear wave propagation in the circumferential detection of pipe structures, thereby eastablishing a CSM-TFM suitable for circumferential inspection of thin-walled pipes. Experiments were performed on a 10 mm-thick flat plate and thin-walled carbon steel pipes (outer diameters: 150 mm, 100 mm, and 75 mm) to compare the imaging performance of M-TFM and CSM-TFM. The results indicate that while M-TFM is effective for defect detection in flat plates, it fails to provide reliable circumferential imaging in curved pipe structures. In contrast, CSM-TFM achieves high-quality imaging for both flat plates and thin-walled pipes with different outer diameters, demonstrating superior defect detectability, image clarity, and circumferential coverage across varying pipe diameters.
