河道敷设供热管道防腐问题的研究

Study of the anticorrosion of the directly buried cross-river heating pipeline

介绍了供热管道内外部的腐蚀机理,从选用耐腐蚀材料、水质、外护管、管道冲洗等方面,阐述了过河管道腐蚀的防范措施,并提出了埋地套管内管道的新型防腐方法,旨在确保供热管线的安全运行。

Combining with the corrosion mechanism of internal and external river channel heating pipeline,from the selection of corrosion resistant materials,water quality,external casing,pipeline flushing and other aspects,elaborated the prevention measures of river channel pipeline corrosion,and put forward the new anticorrosion methods of buried casing inside the pipeline,to ensure the safety operation of heating pipe line.
