直埋供热管道腐蚀成因分析与防腐蚀措施

The Cause Analysis Of Corrosion and Corrosion Protection About Directly Buried Heating Pipeline

我国供热管道主要以直埋敷设为主,为提高系统可靠性,减少维修成本,加强防腐蚀措施是供热系统的重要任务。本文根据腐蚀的机理,从管道特性、土壤特性和供热介质特性等多方面详细阐述了直埋供热管道产生内腐蚀和外腐蚀的主要因素,并介绍了直埋供热管道的防腐蚀措施。

In our country, heating pipeline is directly buried mostly. In orcter to improve me reuut, utLy 7o tern and reduce cost of maintenance, strengthen the anticorrosion measures is an important task of heating system. The article based on the theory of corrosion and combine with pipeline features, soil features and heating medium and so on to explain the main factor that cause inner and outer corrosion of directly buried heating pipeline, and also introduee directly buried heating pipeline anticorrosion measures.
