摘要
对魏荆输油管道的腐蚀防护层状况、恒电位仪运行参数和管道本体状况进行了调查分析 ,认为造成腐蚀的主要原因是防护层老化 ,出现阴极保护死角。采取了加强管道防护层监、检测 ,及时补漏、大修和增设阴极保护装置等措施。
Through investigating and analyzing the bituminous coating, parameters of potentiostats etc. of Weijing oil pipeline, it is concluded that the pipeline corrosion results from the coating aging and shortage of necessary power of cathodic protection in some part of the pipeline. In order to prolong the usage of Weijing oil pipeline some methods are put forward.
