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...
