1、表面技术第44卷第11期112SURFACETECHNOLOGY2015年11月管道内防腐技术现状与研究进展赵帅,兰伟(重庆科技学院冶金与材料工程学院,重庆401331)摘要:介绍了石油管道内溶解氧、二氧化碳、硫化氢、以及二氧化碳和硫化氢协同腐蚀的机理。综述了油气管道内防腐技术,现阶段主要的处理方式是选择耐蚀金属材料或非金属材料、添加缓蚀剂、涂层防腐和衬里防腐。分析了各种内防腐技术的优缺点,认为管道内防腐在未来的发展方向是将基材选择、添加缓蚀剂、内涂镀层和内衬里技术进行综
2、合,以减缓管道内的腐蚀。低碳钢表面镀镍层自纳米合金化技术,即是集中内防腐技术的综合运用,得到了表面无缝冶金结合的高耐蚀性能管材,是未来发展趋势的代表。关键词:管道;防腐;耐蚀材料;缓蚀剂;涂层;镀层;衬里中图分类号:TG174.4文献标识码:A文章编号:1001-3660(2015)11-0112-07DOI:10.16490/j.cnki.issn.1001-3660.2015.11.018PresentStatusandResearchProgressofAnti-corrosionTechnologyinPipelineZHAOShuai,LANWei(Scho
