Corrosion Behavior and Comparative Assessment of Mitigation Alternatives for Buried Natural Gas Pipelines Under Urban Stray Current Influence—A Case Study of HVDC Grounding Electrode Interference
With the large-scale deployment of high-voltage direct current (HVDC) transmission projects, monopolar ground return operation has increasingly intensified stray current interference risks to adjacent buried metallic pipelines. This study investigates a high-pressure natural gas pipeline project in Guangdong Province b...
