摘要
本文从长输管道外腐蚀控制所需考虑的因素出发,结合国内外长输管道外防护技术的特点和防腐蚀层应用的现状,分析、比较了目前主要防护材料的防腐蚀性能。论述了复杂地形条件下,对管道外防护层的选择应综合考虑环境条件、施工条件及经济性因素。最后,对长输管道常用的几种外防腐涂层的应用提出了看法和建议。
This article analyzes all factors should be considered to control the external corrosion for long distance pipeline, combining characteristics of external corrosion prevention technology and the present situation on the application of coating materials at home and abroad. It also discusses the properties of external anti-corrosion materials commonly used. We should consider the environmental conditions, constructional conditions and economy factors to select proper coating materials on the complicated terrain. In the end, the author suggests some opinions and advices on application of several anti-corrosion coating for long distance pipeline.
