Cathodic Protection & Electrochemical Techniques for Corrosion Control in Process Plants
Cathodic Protection & Electrochemical Techniques for Corrosion Control in Oil & Gas, Chemicals, Fertilizers, Petrochemicals, Power Plants, Infrastructure, etc. Corrosion is deterioration of a material, usually metal, that results from a chemical or electrochemical reaction with its environment. Three components responsible for corrosion: 1. Material to be corroded 2. Chemical or electrochemical reaction 3. Surrounding environment 1. Metal usually high carbon steel used in oil and gas pipeline 2. Chemical or electrochemical reaction : Chemical or electrochemical reaction takes place between metal and environment that contains moisture, oxygen and other chemicals which results into decay in metal that is called corrosion. 3. Environment : The surrounding environment responsible for electrochemical reaction is called electrolyte containing moisture, oxygen and other chemicals.
