Corrosion rates of buried pipelines caused by geomagnetic storms
Telluric effects associated with geomagnetic field variations cause currents to flow in burled pipelines, which present a continuing problem/or monitoring cathodfc protection. Protection methods Involving the application of a noncorrosive coating with cathodic protection should present the circulati...

Telluric effects associated with geomagnetic field variations cause currents to flow in burled pipelines, which present a continuing problem/or monitoring cathodfc protection.

This ejfect has a strong dependence on the electrical resistivity oj the host soil, produces a strong current channeling along the pipes, and Increases the risk of corrosion. A method was proposed to quantify the corrosion effects over the pipelines, assuming the geomagnetic field as the external source responsible for the erratic currents.
