The Pipeliners Podcast is continuing a series on inline inspection (ILI) with Marc Lamontagne of the Lamontagne Pipeline Assessment Corporation. In this episode, host Russel Treat and Mr. Lamontagne discuss the important roles of geometry and mapping for inline inspection. In this episode, you will learn about the caliper and geometry tools used for inline inspection, why it's important to have accurate maps to track the movement of a pipeline due to changes in the environment, why highly-trained people are critical to process the data produced by these tools, and more. Stay tuned for more episodes in this inline inspection series covering corrosion, cracks, deformation, and the data that is used in inline inspection.
