Haynes ManualsThe Haynes Author : Marshall Parker, Edward G. Peattie """Description:This update of Marshall Parker's classic text contains the latest ""hands-on"" information for taking measurements and making the calculations necessary for cathodic protection of buried pipe lines. Essentially a practical field manual for corrosion technicians and engineers, it is a simple and direct introduction to the fundamentals of a complex subject. The contents cover soil resistivity surveys, potential surveys, line currents, current requirement surveys, rectifier systems for coated lines, ground bed design and installation, galvanic anodes on coated lines, hot spot protection, bond protection, stray current electrolysis, interference, operation and maintenance, and coating inspection and testing. There are also helpful appendixes that explain the fundamentals of underground corrosion, basic principles of cathodic protection, tables of properties of metals, and attenuation equations. While other books on corrosion are sometimes too theoretical for practical work, Pipe Line Corrosion and Cathodic Protection, Third Edition, shows you how to take actual field measurements and apply them to design a well-protected system.

CATHODIC protection is complementary to the physical protection of metals, since it is used in conditions where painting and similar methods are not practicable, or not wholly satisfactory; in the case of metals which are buried in damp ground or immersed in aqueous fluids. The underlying principle is that, if metal surfaces in need of protection can be made completely cathodic, no corrosion will occur. This is effected by the introduction of an artificial anode which sets up a flow of current, the circuit of which is completed by the aqueous medium acting as the electrolyte. Higgins, W.

Pipeline Corrosion and CP

ASME Press, The prevention of external corrosion on underground structures is accomplished using a dual system of coatings and CP. To define corrosion, pipelines will be considered synonymous with all underground structures. All metallic corrosion is electrochemical in nature and is the result of direct electrical current flow.

Methods and Materials in Cathodic Protection

To understand cathodic protection, you must first understand how corrosion is caused. For corrosion to occur, three things must be present:. Two dissimilar metals 2. An electrolyte water with any type of salt or salts dissolved in it 3.

Marsh, Glenn A.. The corrosion of steel in an aqueous environment proceeds by an electrochemical process, usually controlled by the speed of the cathodic reaction. Over the pH range from 5. Electrons consumed in the cathodic reaction are supplied by the anodic reaction.
