Commercialization of ILI Technology which Accurately Detects, Locates, and Measures Pipeline Girth Weld Defects
Diakont Sensor Identifies Defects Inside Natural Gas Pipelines
Diakont integrated the MS-EMAT sensor on Diakont's existing pipeline robot. In addition, Diakont demonstrated the MS-EMAT sensor on a pipeline in the Pacific Gas and Electric Company service territory. The project is completed, and the final report is published and posted on the Energy Commission's website at http://www.energy.ca.gov/2015publications/CEC-500-2015-028/CEC-500-2015…
Diakont demonstrated its multichannel scanning electromagnetic acoustic transducer (MS-EMAT) fitted on a robotic crawler and performed comprehensive remote in-line inspection of gas pipeline girth welds. The MS-EMAT sensor technology inspects for hidden defects remaining from construction and operational defects, such as cracks induced by ground movement. These types of defects worsen over time and reduce pipeline safety. The sensor provides a comprehensive method to evaluate a pipeline girth weld and provide operators with accurate data on the infrastructure integrity of the California pipeline network. The sensor technology performance has the potential to provide operators with valuable information on critical pipeline features.
Relative to hydrostatic testing, this technology can perform in-line inspection to detect girth weld defects faster and without excavation costs.
Early and timely damage detection using in-line inspection technology will improve reliability of gas pipelines in California.
Early and timely damage detection and adequate measures to prevent pipeline failure will improve safety of gas pipelines in California.
