ART is an ultra-wideband acoustic measurement technology that delivers highly accurate pipeline wall thickness data. Like other ultrasonic technologies, the direct nature of the measurement provides a significant improvement over magnetic 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… technologies, when compared in terms of defectA flaw, anomaly, or imperfection in a pipeline that could compromise its integrity, safety, or performance. Defects can vary in nature, size, and severity and c… detection, classification, and sizing.
