摘　　要：对于阴极保护这一项技术而言,它能够在一定的程度上保护城镇燃气埋地钢管外防腐层的缺点,使其能够在最大的限度中加强生命的周期。但是我们在实际的使用过程中,却可以发现这一项技术它在城镇燃气输配管网中的使用较晚,这便使得城镇燃气输配管网并没有进行相应的专业绝缘隔离设计,使得阴电流流失的情况发生,因此在本篇文章当中,我们主要是简单的探讨了当前城镇燃气输配管网不停输法兰绝缘改造的研究,希望能够提供给相关从事者一些有效的帮助。As far as the cathodic protection technology is concerned,it can protect the shortcomings of the external anti-corrosion coating of urban gas buried steel pipe to a certain extent,so that it can strengthen the life cycle in the maximum extent.However,in the actual use process,we can find that this technology is used later in the urban gas transmission and distribution network,which makes the urban gas transmission and distribution network not carry out the corresponding professional insulation design,making the loss of negative current happen.Therefore,in this article,we mainly discuss the current research on the flange insulation transformation of urban gas transmission and distribution network,hoping to provide some effective help to the relevant practitioners.
