為(wei)提(ti)高(gao)鋼(gang)管的耐(nai)腐(fu)蝕性(xing)能，對一般鋼(gang)管進行鍍(du)鋅。鍍(du)鋅鋼(gang)管分(fen)熱(re)鍍(du)鋅和電(dian)鍍(du)鋅兩種(zhong)，熱(re)鍍(du)鋅鍍(du)鋅層厚(hou)，電(dian)鍍(du)鋅成(cheng)本低，表面不(bu)是很光滑(hua)。吹(chui)氧焊管：用(yong)作(zuo)煉鋼(gang)吹(chui)氧用(yong)管，一般用(yong)小口徑的焊接鋼(gang)管，規格由(you)3/8-2寸八種(zhong)。用(yong)08、10、15、20或者195-Q235的鋼(gang)帶制(zhi)作(zuo)成(cheng)的，為(wei)了防腐(fu)蝕，有(you)(you)的要進行有(you)(you)效滲鋁處理。

老房子大(da)部(bu)分是用(yong)的(de)都是鍍(du)(du)(du)鋅(xin)(xin)管(guan)(guan)(guan)(guan)(guan)(guan)，現(xian)在煤氣(qi)、暖氣(qi)用(yong)的(de)那(nei)種(zhong)鐵管(guan)(guan)(guan)(guan)(guan)(guan)也是鍍(du)(du)(du)鋅(xin)(xin)管(guan)(guan)(guan)(guan)(guan)(guan)，鍍(du)(du)(du)鋅(xin)(xin)管(guan)(guan)(guan)(guan)(guan)(guan)作為水(shui)管(guan)(guan)(guan)(guan)(guan)(guan)，使用(yong)幾(ji)年后，管(guan)(guan)(guan)(guan)(guan)(guan)內(nei)(nei)產(chan)生大(da)量銹垢，流出的(de)黃水(shui)不(bu)僅污染(ran)潔(jie)具，而且(qie)夾(jia)雜著不(bu)光滑(hua)內(nei)(nei)壁滋生的(de)細菌，銹蝕造(zao)成(cheng)水(shui)中重(zhong)金屬含量過(guo)高，嚴重(zhong)危害人體的(de)。六七(qi)十年代(dai)，國際上發(fa)達 開始開發(fa)新(xin)型管(guan)(guan)(guan)(guan)(guan)(guan)材，并陸續禁用(yong)鍍(du)(du)(du)鋅(xin)(xin)管(guan)(guan)(guan)(guan)(guan)(guan)。中國建(jian)設部(bu)等四(si)部(bu)委也發(fa)文明確從二000年起禁用(yong)鍍(du)(du)(du)鋅(xin)(xin)管(guan)(guan)(guan)(guan)(guan)(guan)，目前新(xin)建(jian)小區的(de)冷水(shui)管(guan)(guan)(guan)(guan)(guan)(guan)已經很少使用(yong)鍍(du)(du)(du)鋅(xin)(xin)管(guan)(guan)(guan)(guan)(guan)(guan)了，有些小區的(de)熱水(shui)管(guan)(guan)(guan)(guan)(guan)(guan)使用(yong)的(de)是鍍(du)(du)(du)鋅(xin)(xin)管(guan)(guan)(guan)(guan)(guan)(guan)。
