Close proximity of high voltage lines and metallic pipelines becomes more frequent. This paper presents a recently developed simulation software to facilitate prediction and mitigation. Flexible (no limitation on number of pipes, transmission lines, bonds, groundings, coating and soil resistivity), user-friendly and robust.
In the present paper, characteristics of the AC corrosion problem are demonstrated using laboratory results and field measurements as examples. Evidence has been given that the AC corrosion mechanisms involve alkalization of the environment nearby the coating defect, and in combination with AC, corrosion may be induced.
