埋地管道牺牲阳极阴极保护中a和E0的确定

Determination of a and E0 on Cathodic Protection System of Underground Pipelines with Sacrificial Anodes

    摘要
  • 摘要: 通过对埋地煤气管线实施牺牲阳极阴极保护的大量测试数据,经系统整理分析,得出电位衰减系数a与修正系数r和涂层电导之间的关系,以及通电点管地电位偏移量E0的计算公式。

     

    Abstract: The equation of negative shift “E0” of pipe/ground potential at connection point, the relation-ship between potential attenuation coefficient “a” and calibration coefficient “r” as well as electric conductivity “g1” of coating are dedueecl by systematic analysis a vast amount of experimental data collected from cathodic protection system of underground pipelines with sacrificial anodes.
