Monogram Electric Resistance Weld – Potential Hazard
On July 3, 2019, the NEB issued safety advisory NEB SA 2019-01 to inform pipeline operators of a potential hazard regarding API 5L Monogram Electric Resistance Weld pipe joints manufactured by Hyundai Steel in their Ulsan, South Korea, mill.
A review of recent pipeline incidents in Alberta did not find any links to the hazard identified in NEB SA 2019-01. However, this hazard, if present, could lead to pipeline integrity issues in the future. As such, the AER reminded licensees that they must conduct an engineering assessment if they become aware of a condition that can lead to failures in their pipeline systems.
