APPLICATION OF NERNST EQUATION FOR CORROSION RESEARCH OF UNDERGROUND PIPELINE

Employing the Nernst Equation the electrode potential of any possible corrosion galvanic cell may be calculated.Therewith,the possible oxidizer may be estimated which may result in corrosion of pipeline.Based on a corrosion survey and the calculation,the main cause of pipeline corrosion may be clearly analyzed.Finally according to the foregoing method,one pipeline was analyzed,as an example,in detail.
