- 摘要:
- 结合钢质管道与钢质储罐阴极保护工程的情况,研究探讨了埋地管道和储罐阴极保护电流密度及保护电流的确定,并与规范中的推荐值进行对比。介绍了恒电位仪主要参数的确定,对长输管道穿越公路、铁路、水渠处阴极保护方案、新旧管道交叉交汇处阴极保护方案及钢质储罐如何合理设置接地装置提出了建议。
Associated with the practical application of cathodic protection for steel pipeline and storage tank, this paper probes into the proper cathodic protection current density and protection current for buried pipeline and tank, and compares them with the recommended values listed in relevant codes. It illustrates the determination of the main parameters of a potentiostat, proposes the cathodic protection scenarios of pipeline crossing highway, railway and water channel as well as the cathodic protection scenario of intersection of old and new pipelines, and explains how to set up a grounding device as well.2009,2(2): 46-49 收稿日期：2008-3-28分类号：U177.1作者简介：杨万国(1961-),男,甘肃武威人,高级工程师,注册自动化系统工程师,1981年毕业于兰州石油学校自动化仪表专业,后取得专科、本科学历,现从事电气、仪表、通信、阴极保护工程施工及管理工作,发表相关论文7篇.参考文献：
