沙特阿美输油管道现场FBE内防腐补口技术

Field FBE internal anticorrosion coating of oil pipelines in Saudi Aramco

在沙特阿美标准体系下进行输油管道的现场FBE(Fusion-Bonded Epoxy)内防腐补口施工尚属首次。结合沙特拉斯坦努拉管道工程实际,介绍了沙特阿美FBE内防腐现场补口技术,阐述了FBE内防腐现场补口设备、防腐补伤材料、人员配置、环境要求、施工流程、工艺措施、安全要求、施工注意事项等内容。工程实践证明,在本项目管道环焊缝的FBE内防腐现场补口施工中,166道环焊缝仅有2道补口不合格,一次合格率达到了98.79%,施工进度达到5道/d,提高了施工效率,降低了施工成本。该项目的成功实施对今后在沙特进行类似工艺管道FBE内防腐现场补口施工有一定的指导意义。

It is the first time that the field FBE(Fusion-Bonded Epoxy)internal anticorrosion coating of oil pipeline has been carried out under the Saudi Aramco standard system.Combining with the actual situation of the Saudi Ra's Tannūrah pipeline project,this paper introduces the technology of field FBE internal anticorrosion coating in Saudi Aramco,and expounds the contents of field coating equipment,anticorrosion material,staffing,environmental requirements,construction process,technical measures,safety requirements,construction matters needing attention.Engineering practice has proved that in the construction of the field FBE internal anticorrosion coating of the pipe girth welds in this project,there are only 2 unqualified girth welds of 166 girth welds,the one-time pass rate is 98.79%,and the construction schedule is 5 girth welds per day,which improves the construction efficiency and reduces the construction cost.The successful implementation of the project has certain guiding significance for the construction of field FBE anticorrosion coating of similar process pipelines in Saudi Arabia in the future.
