Aberdeen Branch Event – Developments in remote magnetic monitoring of carbon steel pipelines to locate and measure abnormal stress

April 29 @ 12:00 pm - 1:00 pm

Developments in remote magnetic monitoring of carbon steel pipelines to locate and measure abnormal stress
1 hr | Free

Hamed Habibi | Spier Hunter

This presentation outlines recent developments in an emerging non-intrusive sensing technique developed to detect localised abnormal pipe wall stress by mapping variations in the earth’s magnetic field around pipelines. Corrosion, metallurgical defects and ground movements result in areas of increased localised stress in pressurised pipelines and a direct relationship has been described mathematically relating magnetic field characteristics to the magnitude of stress due to magnetostriction. The presentation explores how measurements of remote magnetic field can be applied to define the location of defects in operational pipelines, quantify the associated abnormal stress, report the position of girth welds and to concurrently report a 3-dimensional map of the pipeline route.
