Multi-Physical Analysis of the Corrosion of Buried Pipes due to Nearby High Voltage Transmission Lines

摘要

In this contribution we present the multi-physical analysis of the induction-corrosion process undergone by a buried pipe that experiences electromagnetic induction from a nearby High Voltage Transmission Line (HVTL). The scenario analyzed models a typical situation found in Colombia by using realistic characteristics of the pipe, the HVTL, and environmental parameters such as soil resistivity. The results presented provide a quantitative view of the corrosion process and constitute a useful tool for the analysis and design of the increasingly common situation of pipelines running near HVTLs. 1
