各有关单位: 传统的镀锌钢管及其配套管件作为水管应用已经有近百年的历史,铜管作为供水管的应用也已有较长的时间。但是,上述供水管均存在着很大的缺陷,如镀锌管在使用过程中容易生,产生“白水”、“红水”现象,铜管在酸性水质(如使用液氯消毒自来水会出现酸性水)的情况下,会生成氯化铜等毒性物 The relevant units: the traditional galvanized steel pipe and its supporting pipe as the water pipe application has been nearly a hundred years of history, as a water supply pipe brass has also been a long time. However, there is a big flaw in the above water supply pipes. For example, the galvanized pipe is easy to be born during use, resulting in “white water” and “red water” phenomenon. When the copper pipe is in acid water quality Tap water acidic water occurs), will produce toxic substances such as copper chloride
