A CLEAR PICTURE

摘要

Inline inspection of axial strain provides additional information regarding the integrity of pipelines in landslide conditions. Mohamed ElSeify (Canada), Stuart Clouston (Canada), Dennis Janda (USA) and Yongtao Zhu (Canada), Baker Hughes, with Doug Dewar (Canada), Enbridge, explain. Inline inspection (ILI) remains a highly effective and widely used method for assessing the integrity of pipeline systems. Over the past two decades, the use of inspection tools equipped with inertial measurement units (IMUs) to map pipelines, measure bending strain and monitor pipe movement, has grown from a niche application to a routine measurement that is performed in thousands of inspection runs each year. However, while IMU measurements effectively identify areas of localised bending strains, they do not detect axial strains.
