Nernst方程在埋地管线腐蚀研究中的应用

APPLICATION OF NERNST EQUATION FOR CORROSION RESEARCH OF UNDERGROUND PIPELINE

应用Nernst方程计算出各可能的腐蚀原电池电极电位 ,从而判断出引起管线腐蚀的可能的氧化剂 ,结合腐蚀调查分析出管线腐蚀的主要原因 .

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.
