钢套管内金属管道的腐蚀及防护

Case Study on the Corrosion of Steel Pipeline in Sleeve and Pipeline Protection

分析了钢套管内金属管道的腐蚀原因,提出了相应的防护措施,并对取消套管穿越措施进行了探讨,指出穿越套管内管道的腐蚀问题应在设计、施工等环节引起重视。

The reason for metal pipeline corrosion in steel casing is analyzed and corresponding countermeasures against the corrosion are set up. A discussion on the depth of buried pipe segment at highway crossing or railway crossing is carried out. It is pointed out that more attention should be paid on the issue of steel pipeline corrosion in steel casing during design and construction stages.
