摘　　要：对管道内壁实施阴极保护的主要技术问题 :保护距离 ,阳极材料 ,阴极结垢等进行了分析和探讨 ,给出了计算保护距离的公式 ;提出了以铜芯外包钛再镀铂 (或钌、铱、铟等混合金属氧化物层 )做线状阳极材料 ,可以提高保护距离 ;指出了阴极结垢问题及防止的方法。Some main technical issues for cathodic protection (CP) of pipeline interior surface, i. e., protection distance, anode material and scale formation on cathodic surface etc were studied. Two formulas for calculating CP distance were derived. It is demonstrated that CP distance can be increased by using a linear anode material consisting of Ti-cladded copper core with plating of Pt (or mixed metal oxide such as Ru, In, Ir, etc.). A method for preventing the scale formation on cathodic surface was developed.
