Design of Cathodic Protection for Underground Crude- Oil Pipeline by sacrificial anodes systems

Abstract

Cathodic protection is the most important of all approaches to corrosion control and for underground crude oil pipelines .In petroleum industry cathodic protection, is a precautionary measure used to provide complete corrosion protection to ferrous metal structures and tubes as their surfaces are exposed to soil or water, as they begin to gradually erode when in contact with soil or water under the influence of Chemical reactions accompanied by an electric current flowing. Sacrificial anode cathodic protection is one of the most widely used methods in protecting underground petroleum pipelines against the corrosion damages. The object of this study is to design of cathodic protection for underground crude-Oil Pipeline by sacrificial anodes systems to be used in the protection of the petroleum pipelines that pass through the Naseer oilfield to the EL Brega region.
