Stray Current Pipeline Corrosion

Application ID: 54761

The impressed current cathodic protection (ICCP) system is often employed to mitigate corrosion of buried pipelines in the oil and gas industry. Metallic objects such as buried pipelines, which are present within the current flow of the ICCP system, may suffer from the stray current interactions leading to accelerated corrosion.

This tutorial model demonstrates stray current corrosion of a buried pipeline, which is in the vicinity of a crossing pipeline that is protected by an ICCP system. The model calculates and predicts the corrosion rate of the nonprotected pipeline, which is much higher close to the crossing.

This model example illustrates applications of this type that would nominally be built using the following products:
