鍍(du)(du)鋅(xin)(xin)鋼(gang)管(guan)(guan)(guan)分為冷(leng)鍍(du)(du)鋅(xin)(xin)鋼(gang)管(guan)(guan)(guan)、熱(re)鍍(du)(du)鋅(xin)(xin)鋼(gang)管(guan)(guan)(guan)，冷(leng)鍍(du)(du)鋅(xin)(xin)鋼(gang)管(guan)(guan)(guan)已被(bei)禁(jin)用(yong)(yong)，后者還被(bei)國(guo)家提倡(chang)暫時(shi)能使用(yong)(yong)。六七十年代，國(guo)際上(shang)發(fa)達國(guo)家開始開發(fa)新型管(guan)(guan)(guan)材，并陸續(xu)禁(jin)用(yong)(yong)鍍(du)(du)鋅(xin)(xin)管(guan)(guan)(guan)。中國(guo)建設部等四(si)部委也發(fa)文明確從(cong)2000年起禁(jin)用(yong)(yong)鍍(du)(du)鋅(xin)(xin)管(guan)(guan)(guan)作為供(gong)水管(guan)(guan)(guan)，新建小(xiao)區(qu)的(de)冷(leng)水管(guan)(guan)(guan)已經很少使用(yong)(yong)鍍(du)(du)鋅(xin)(xin)管(guan)(guan)(guan)了(le)，有(you)些(xie)小(xiao)區(qu)的(de)熱(re)水管(guan)(guan)(guan)使用(yong)(yong)的(de)是鍍(du)(du)鋅(xin)(xin)管(guan)(guan)(guan)。熱(re)鍍(du)(du)鋅(xin)(xin)鋼(gang)管(guan)(guan)(guan)在消防、電力和高速公路(lu)上(shang)有(you)廣(guang)泛的(de)應用(yong)(yong)。

熱鍍鋅鋼(gang)管廣泛(fan)應用于建(jian)筑、機(ji)械(xie)、煤(mei)礦、化工(gong)、電(dian)力(li)、鐵道車(che)輛、汽車(che)工(gong)業(ye)、公路、橋梁、集裝(zhuang)箱、體育設(she)施、農業(ye)機(ji)械(xie)、石油機(ji)械(xie)、探礦機(ji)械(xie)等制(zhi)造工(gong)業(ye)。

鍍(du)鋅(xin)鋼(gang)管(guan)(guan)(guan)表(biao)面(mian)有熱浸鍍(du)或電鍍(du)鋅(xin)層的焊接鋼(gang)管(guan)(guan)(guan)。鍍(du)鋅(xin)可(ke)增加(jia)鋼(gang)管(guan)(guan)(guan)的抗腐蝕能力(li)，延長使(shi)用(yong)壽命。鍍(du)鋅(xin)管(guan)(guan)(guan)的用(yong)途(tu)很廣，除作(zuo)輸水(shui)、煤氣、油等(deng)(deng)一般低壓力(li)流體的管(guan)(guan)(guan)線(xian)管(guan)(guan)(guan)外，還用(yong)作(zuo)石油工業(ye)特別(bie)是海洋油田的油井管(guan)(guan)(guan)、輸油管(guan)(guan)(guan)，化工焦化設備(bei)的油加(jia)熱器、冷(leng)(leng)凝冷(leng)(leng)卻器、煤餾洗油交(jiao)換器用(yong)管(guan)(guan)(guan)，以(yi)及棧橋管(guan)(guan)(guan)樁(zhuang)、礦山坑道的支撐(cheng)架用(yong)管(guan)(guan)(guan)等(deng)(deng)。
