Development and Validation of a Novel Gas Crack Detection Tool Using Guided Waves

In this paper, the authors describe the development and validation of an inline inspection (ILI)A method used to assess the the integrity and condition of pipelines. It involves the use of specialized tools that are inserted into the pipeline and propelled… crackA fracture or discontinuity in the wall of a pipeline, where the material is separated or broken, potentially compromising the integrity and safety of the pipel…‑detection
