摘要
油气集输管道容易腐蚀、结垢,造成压力增高、能耗增加,并存在失效风险。介绍了集输管道原位内涂层防腐施工工艺,以及在ZX1海上平台至陆地联合站Ф457mm管道的应用实例。涂层材料为bar-rust 257多功能环氧树脂,厚度为20～30μm,可有效降低输油能耗,延长管道使用寿命。
In situ internal coating process and application of the process in the offshore pipeline from ZX1 platform to union stations ashore. The process was completed through preparation, sur- face cleaning,coating process and inspection et al; dry film thickness was 20-30 μm at last. This process can reduce energy costs and increased pipeline life.
