简要介绍了大庆油田埋地管道腐蚀和外防腐材料现状。对埋地管道外腐蚀原因并针对外防腐结构和外选材的不合理性 ,更新改造工程的“以换代修”等问题进行了分析。为提高埋地管道外防腐工程质量 ,建议根据管道工程实际条件 ,对外防腐方案进行充分的技术经济论证 ,并应尽快制定旧管道更换和维修标准及界限 ,加强长输管道外防腐的检测和评价等工作。
Briefly introduces the status quo of corrosion and external anticorrosive materials of buried pipeline in Daqing Oilfield. The reasons for the corrosion of buried pipelines are analyzed and the problems such as the unreasonableness of outer anticorrosive structure and outer selection materials and the “replacing and repairing” project of renovation and reconstruction project are analyzed. In order to improve the quality of anti-corrosion engineering of buried pipelines, it is suggested to conduct sufficient technical and economic feasibility studies on external anti-corrosion programs according to the actual conditions of pipeline engineering. Standards and boundaries for replacing and repairing old pipelines should be formulated as soon as possible to enhance the detection and evaluation of anti-corrosion of long-distance pipelines Wait for work.
