Corrosion Causes of Buried Metal Pipelines and Anti-corrosion Measures

Metal pipelines buried underground for long time,which are influenced by chemical corrosion and electrochemical corrosion,finally lead to corrosion failure of metal pipelines.In order to reduce the corrosion rate of pipelines and extend the service life of pipelines,the corrosion reasons and main corrosion factors of the buried pipelines were analyzed.Effective anti-corrosion measures were put forward.
