Corrosion of Underground Water Pipelines

介绍了中国石油天然气股份有限公司大庆石化分公司地下输水管网的腐蚀现状与调查分析情况,提出了对地下输水管网实施以深井阳极地床外加电流阴极保护为主、局部欠保护区辅以镁合金牺牲阳极的阴极保护方案。经分析,采取上述防护措施后,每年可产生2488万元的经济效益。

The corrosion and corrosion analysis of the underground water pipelines in PetroChina Daqing Petrochemical Company are described. The cathodic protection system of deep-well anode bed with applied current coupled with Al-alloy sacrificing anode in certain areas is recommended. An annual benefit of 24,88 million Yuan （RMB） can be achieved by the acove measures.
