摘要
北滩油库输油管道的镁阳极使用 6年后 ,北京一条液化气管道镁阳极埋于菜地使用 14年后 ,都仍能输出相当大的保护电流 ;与之相反 ,埋于土壤不那么潮湿的野草地里的镁阳极只能输出小得多的电流。锌阳极的情况与镁阳极相似。这说明把带填料的牺牲阳极埋于持久潮湿的土壤里 ,才能长期正常运行。
After six years′usage, the Magnesium Anodo that protocting the oil pipeline of Beitan oil depot can still output sizeable protecting current. And after fourteen years′usage, the magnesium anode that protecting another LNG pipeline can also output sizeable protecting current. On the contrary, the magnesium anode that buriod in dryness area can only output lesser current. The magnesium anode work normally can when it was buried in moist earth with backfilling .
