Ultrasonic guided wave techniques and applications in pipeline defect detection: A review

Ultrasonic guided wave techniques are extensively applied in the non-destructive testing and structural health monitoring (SHM) of oil and gas pipelines due to its advantages of wide coverage, high screening efficiency, and cost-effectiveness. This paper presents a comprehensive review of the applications of ultrasonic guided wave techniques in pipeline defect detection, including developments in pipeline ultrasonic guided wave theory, advances in transducers for pipeline ultrasonic guided wave detection, the interaction between ultrasonic guided waves and pipeline defects and features, signal processing techniques for pipeline detection and monitoring. This paper aims to provide valuable references for researchers involved in ultrasonic guided wave-based pipeline detection through a comprehensive review.
