摘　　要：站场埋地管道的腐蚀控制比较复杂,本文针对可用于站内埋地管道防腐的5种防腐方式进行了优缺点对比分析,并给出推荐的埋地管道防腐层选用原则:即在大型项目中宜优先采用3LPE防腐层,小型改造项目中宜选用无溶剂液体环氧涂层+聚丙烯胶粘带或粘弹体胶带+聚丙烯胶粘带的防腐方式。Corrosion control of buried pipelines in petroleum and gas stations is very complicated.This paper compares and analyzes the advantages and disadvantages of five anti-corrosion methods that can be used for anti-corrosion of buried pipelines in the station,and gives the recommended selection principles of anti-corrosion layers for buried pipelines.That is,3LPE should be preferred in large-scale projects,and the anti-corrosion method of solvent-free liquid epoxy coating+polypropylene adhesive tape or viscoelastic tape+polypropylene adhesive tape should be used in small-scale renovation projects.
