Assessment of corrosion on buried metallic pipeline induced by AC interference below high transmission line

High voltage alternating current (HVAC) transmission line is usually shared the same right of way with buried metallic pipeline. Long-term exposure of inductive coupling on buried metallic pipeline will cause AC corrosion at any coating defects on the pipeline. In the West Coast of Malay Peninsula,...
