长输管道的防腐措施及施工要点

Corrosion Prevention Measures and Construction Keys of Long-distance Pipeline

金属管道在自然环境下会受到腐蚀,使管道本身的结构或力学性能退化甚至破坏。因此在长输管道类型的工程建设中,应根据不同管道类型和规格,采取相应的技术措施,降低腐蚀对长输管道造成的不利影响。本文以大伙房输水(二期)工程为例,介绍了长输管道的常规防腐措施及施工要点。

Metal pipelines would be subject to corrosion in the natural environment so that the structure or mechanical properties of the pipe itself can be degraded or even destructed. Therefore,appropriate technical measures should be adopted to reduce the adverse effects of corrosion on long-distance pipe in the project construction of long-distance pipe according to different pipe types and sizes. In the paper,Dahuofang Water Transfer（ Stage Ⅱ） Project is adopted as an example for introducing conventional anti-corrosion measures and construction keys of long-distance pipes.
