摘要:: 报道袋装牺牲阳极阴极保护方法在埋地输气管线施工中的应用,从工艺原理、袋装牺牲阳极的制作、埋设以及运行与维护等方面进行了介绍.袋装牺牲阳极阴极保护方法具有不需外部电源、对邻近构筑物干扰小、保护电流分布均匀、利用率高、工程量小、经济效益高等优点.
The paper reported application of the galvanic anode bag for cathodic protection during buried pipeline construction e.g.from process princi-ple,galvanic anode bag manufacture,buried method to running & maintenance.The galvanic anode bag needen't other power & has a less interfere-nce to other facilities.Also,the anode protection current distribution is uniform & utilization efficiency is high.The anode cost is low & e-conomic benef it is good.
