Determining the Extent of Corrosion on Gas Pipelines

Короткий зміст

This final rule requires that when gas pipeline operators find harmful external corrosion on buried metallic pipelines that have been exposed, they must investigate further to determine if additional harmful corrosion exists in the vicinity of the original exposure. Further investigation can help determine the significance of the initial corrosion discovery. The new requirement may prevent accidents due to corrosion that might otherwise go undetected near an exposed portion of pipeline.
