Corrosion On Pipelines
Buried steel pipelines for the transport of gases and of crude oil, brine, and chemical products must be cathodically protected against corrosion according to technical regulations.
Corrosion has been a problem since man began to use metals. Except for gold and a few other metals, metals do not occur as a basic element in nature.
Impressed current cathodic protection is a method used in corrosion control to reduce the dissolution of anodic structures by reducing the difference between potential energy & the cathodic
Galvanic Corrosion is an electrical-chemical process where one of the metals are more likely to corrode than the other, when both metals are linked electrically.
