Distribution of Stray Current in the Buried Metallic Pipeline Based on Inducted Electric Field

Article Preview

Abstract:

Stray current flows through the buried metallic pipeline which exposed to electrochemical corrosion attack. The distribution of stray current is studied by Finite Element Method analysis model, the results indicate that stray current increase gradually along the buried metallic pipeline, reaching to a maximum value in an intermediary point, and then decreases gradually, has a regular bilateral symmetry. The distribution model of stray current is discussed by the inducted electric field theory.
