Description

Currents on gas pipelines are known to arise from intentional sources such as impressed current systems used for cathodic protection and from unintended and often unknown sources including local transit systems, power stations and a range of telluric sources. Under some conditions these stray currents can be large enough to present a potential threat to the integrity of the pipeline through accelerated local corrosion. This is even true for nominally cathodically protected systems if the magnitudes of the stray currents are sufficiently large.

Magnetometer-Based Measurements of Stray Current Distribution on Cathodically Protected Gas Transmission Pipeline
