鍍鋅管的介紹 

　　鍍(du)(du)(du)鋅(xin)鋼(gang)管(guan)(guan)分為冷鍍(du)(du)(du)鋅(xin)鋼(gang)管(guan)(guan)、熱鍍(du)(du)(du)鋅(xin)鋼(gang)管(guan)(guan)，冷鍍(du)(du)(du)鋅(xin)鋼(gang)管(guan)(guan)已(yi)被禁(jin)(jin)用(yong)(yong)(yong)，后(hou)者還被國(guo)家(jia)(jia)提倡暫時能使用(yong)(yong)(yong)。六七十年代，國(guo)際(ji)上發(fa)達(da)國(guo)家(jia)(jia)開始(shi)開發(fa)新型(xing)管(guan)(guan)材(cai)，并陸續禁(jin)(jin)用(yong)(yong)(yong)鍍(du)(du)(du)鋅(xin)管(guan)(guan)。中(zhong)國(guo)建設部(bu)(bu)等四部(bu)(bu)委也發(fa)文明確從2000年起禁(jin)(jin)用(yong)(yong)(yong)鍍(du)(du)(du)鋅(xin)管(guan)(guan)作為供(gong)水(shui)管(guan)(guan)，新建小(xiao)區(qu)的(de)(de)冷水(shui)管(guan)(guan)已(yi)經很少使用(yong)(yong)(yong)鍍(du)(du)(du)鋅(xin)管(guan)(guan)了，有些小(xiao)區(qu)的(de)(de)熱水(shui)管(guan)(guan)使用(yong)(yong)(yong)的(de)(de)是鍍(du)(du)(du)鋅(xin)管(guan)(guan)。熱鍍(du)(du)(du)鋅(xin)鋼(gang)管(guan)(guan)在(zai)消防、電(dian)力和高速(su)公路上有廣泛的(de)(de)應用(yong)(yong)(yong)。
