摘要
文章介绍了目前国内外长输管道外防护技术的特点和防护层应用的现状,分析了常用防腐蚀材料的防腐蚀性能。指出在山区复杂地形条件下,应考虑环境条件和施工条件,并通过技术经济分析对管道外防腐蚀层进行合理选择。
The techniques and application of external protection of long-distance pipelines are discussed, and the conventional corroslon-resistant materials and their corrosion-resisting performances are analyzed. It is pointed out that, for the pipeline in compllcated topographical conditions, the proper external corrosion protection measures should be selected in consideration of environmental and site construction conditions and economic analysis.
