摘　　要：为明确埋地热力管线腐蚀失效的主要形式,提高供暖质量。以下就以埋地热力管线几种主要的腐蚀失效作为论述对象,着重论述了不同腐蚀失效形式的成因。结果显示,包括管道自身原因、管道外部及内部环境等都可能引起管道腐蚀失效。可见,埋地热力管线的腐蚀原因较为复杂,但并非无法治理,故本文还提出了几点防控埋地管线腐蚀失效的措施,希望能为相关领域工作者提供一定参考。To clarify the main forms of corrosion failure in buried thermal pipelines and improve heating quality.The following focuses on the main corrosion failures of buried thermal pipelines,with a particular emphasis on the causes of different forms of corrosion failures.The results show that pipeline corrosion failure may be caused by factors such as the pipeline itself,the external and internal environment of the pipeline.It can be seen that the corrosion causes of buried thermal pipelines are relatively complex,but it is not impossible to treat them.Therefore,this article also proposes several measures to prevent and control the corrosion failure of buried pipelines,hoping to provide some reference for workers in related fields.
