Numerical Analysis of the Corrosion of Buried Pipes near High Voltage Transmission Lines

摘要

We present the multi-physical analysis of theinduction-corrosion process undergone by a buried pipe subjectto electromagnetic induction from a nearby High VoltageTransmission Line (HVTL). The scenario analyzed models a typicalsituation found in Colombia by using realistic characteristics ofthe pipe, the HVTL, and environmental parameters such as soilresistivity. The results presented provide a quantitative view of thecorrosion process and constitute a useful tool for the analysis anddesign of the increasingly common situation of pipelines runningnear HVTLs.
