摘要
分析了埋地钢质燃气管道在水泥套管、铸铁套管、做外防腐的钢套管内的腐蚀情况,讨论了采用带状镁(锌)阳极、镯状阳极的局部阴极保护方法。
The corrosion of buried steel gas pipeline in sleeves such as cement sleeve, cast iron sleeve, external anti-corrosive steel sleeve is analyzed, and the local cathodic protection method using ribbon magnesium (zinc) anode and ring anode is discussed.
