浅析埋地燃气钢管防腐

Analysis on Corrosion Protection of Steel Gas Pipe Underground

概述了地下燃气钢管腐蚀的分类,重点分析了电化学腐蚀的方式和机理,对目前应用较为广泛的两种防腐方法即绝缘层防腐法和电保护法作了介绍,并给出了应用实例。

The paper describes the corrosion type of steel gas pipe underground, analyzes the corrosion mode and mechanism of electrochemistry. Two ways of corrosion protection applied abroad are introduced, that are isolation layer anti-corrosion and electricity protect anti-corrosion. Some examples are also given in this paper.
