CATHODIC PROTECTION BASIC PRINCIPLES AND

Cathodic Protection is an industrial technique for controlling metallic corrosion that occurs in the Anode by oxidation and metal is lost, whereas in the cathode protection occurs by the reduction reaction. So in the cathodic protection technique, the concerned metal is converted into the cathode of the electrochemical corrosion cell.CATHODIC PROTECTION OF UNDERGROUND STEEL One of the types of cathodic protection is sacrificial anode or galvanic cathodic protection. Corrosion occurs through the loss of the metal ions at anodic area to the electrolyte. Cathodic areas are protected from corrosion because of the deposition of hydrogen or other ions that carry current (Sandoval, A., Beruvides, M., Wiesner, T.F. 2001). By using the sacrificial anode technique the steel pipe will CATHODIC PROTECTION SYSTEM DESIGN.pptCathodic Areas Anodic Area Pipe Wood Bed Block .
