摘要
根据生产实践和管道防腐涂料的发展状况 ,结合埋地管道涂层的国际规范RP0 6 19的规定和该涂层的国内技术规范 ,分析了该涂层对城市埋地管道防腐工程存在的问题和弊端。
Currently coal tar epoxy is widely used as anti corrosion coating for underground pipelines in China.However,as new anti corrosion technology is developed and international standards are updated,this method seems not to be the best choice in anti corrosion practice.This paper thus summarizes the problems existed in the current anti corrosion coating method on the basis of experience and the standard in NACE RP 0169'Control of External Corrosion on Underground or Submerged Metallic Piping Systems'.
