其實鍍鋅鋼管分為冷(leng)鍍(du)鋅鋼(gang)(gang)管(guan)(guan)、熱鍍(du)鋅鋼(gang)(gang)管(guan)(guan),冷(leng)鍍(du)鋅鋼(gang)(gang)管(guan)(guan)已(yi)被(bei)禁用,后者還被(bei)提倡暫時能使用。
產品應用
熱鍍(du)鋅鋼(gang)管廣泛(fan)應用(yong)于(yu)建(jian)筑、機(ji)(ji)械(xie)(xie)、煤礦(kuang)、化工(gong)、電力、鐵道車輛、汽車工(gong)業(ye)、公路、橋(qiao)梁、集裝箱、體育設施、農業(ye)機(ji)(ji)械(xie)(xie)、石(shi)油(you)機(ji)(ji)械(xie)(xie)、探礦(kuang)機(ji)(ji)械(xie)(xie)、大棚建(jian)設等制造(zao)工(gong)業(ye)。
鍍鋅鋼管表面有熱浸鍍或電鍍鋅層的焊接鋼管。鍍鋅可增加鋼管的抗腐蝕能力,延長使用壽命。鍍鋅管的用(yong)(yong)途很(hen)廣,除(chu)作輸水、煤氣、油(you)等一般低壓力流體的管線管外,還用(yong)(yong)作石油(you)工(gong)業特別(bie)是海洋油(you)田(tian)的油(you)井管、輸油(you)管,化工(gong)焦化設(she)備的油(you)加熱器(qi)、冷凝(ning)冷卻(que)器(qi)、煤餾洗油(you)交換器(qi)用(yong)(yong)管,以(yi)及棧橋管樁、礦山坑道的支(zhi)撐(cheng)架用(yong)(yong)管等。

詳細介紹
熱鍍鋅管
鍍鋅管
鍍鋅管(3張)
熱(re)(re)鍍(du)鋅(xin)管(guan)是(shi)(shi)使(shi)熔(rong)融金(jin)屬與鐵基體(ti)反應(ying)而產(chan)生合金(jin)層(ceng)(ceng)(ceng),從而使(shi)基體(ti)和鍍(du)層(ceng)(ceng)(ceng)二者相結(jie)合。熱(re)(re)鍍(du)鋅(xin)是(shi)(shi)先(xian)將鋼(gang)(gang)管(guan)進行(xing)酸洗(xi),為了去除鋼(gang)(gang)管(guan)表面的氧化(hua)(hua)鐵,酸洗(xi)后,通過(guo)氯(lv)化(hua)(hua)銨或(huo)(huo)氯(lv)化(hua)(hua)鋅(xin)水溶(rong)液(ye)或(huo)(huo)氯(lv)化(hua)(hua)銨和氯(lv)化(hua)(hua)鋅(xin)混(hun)合水溶(rong)液(ye)槽中(zhong)進行(xing)清洗(xi),然后送入熱(re)(re)浸(jin)鍍(du)槽中(zhong)。熱(re)(re)鍍(du)鋅(xin)具(ju)有鍍(du)層(ceng)(ceng)(ceng)均勻,附著力(li)強,使(shi)用壽命(ming)長等優點。熱(re)(re)鍍(du)鋅(xin)鋼(gang)(gang)管(guan)基體(ti)與熔(rong)融的鍍(du)液(ye)發(fa)生復雜的物理、化(hua)(hua)學反應(ying),形成耐(nai)腐蝕(shi)(shi)的結(jie)構緊密的鋅(xin)一鐵合金(jin)層(ceng)(ceng)(ceng)。合金(jin)層(ceng)(ceng)(ceng)與純鋅(xin)層(ceng)(ceng)(ceng)、鋼(gang)(gang)管(guan)基體(ti)融為一體(ti),故其(qi)耐(nai)腐蝕(shi)(shi)能(neng)力(li)強。
冷鍍鋅管
冷(leng)(leng)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)管(guan)(guan)(guan)(guan)就是電鍍(du)(du)(du)(du)鋅(xin)(xin)(xin),鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)量(liang)很(hen)少,只有10-50g/m2,其本身的(de)(de)耐腐蝕性比熱鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)管(guan)(guan)(guan)(guan)相(xiang)差很(hen)多。正規的(de)(de)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)管(guan)(guan)(guan)(guan)生產(chan)廠家,為(wei)了(le)保(bao)證質量(liang),大多不(bu)采(cai)用(yong)電鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(冷(leng)(leng)鍍(du)(du)(du)(du))。只有那些規模小、設備陳舊的(de)(de)小企業采(cai)用(yong)電鍍(du)(du)(du)(du)鋅(xin)(xin)(xin),當然他們的(de)(de)價格也(ye)相(xiang)對便宜一些。建設部已正式下文,淘汰技術落后的(de)(de)冷(leng)(leng)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)管(guan)(guan)(guan)(guan),不(bu)準(zhun)用(yong)冷(leng)(leng)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)管(guan)(guan)(guan)(guan)作水、煤氣管(guan)(guan)(guan)(guan)。 冷(leng)(leng)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)鋼(gang)管(guan)(guan)(guan)(guan)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)層(ceng)是電鍍(du)(du)(du)(du)層(ceng),鋅(xin)(xin)(xin)層(ceng)與鋼(gang)管(guan)(guan)(guan)(guan)基體(ti)獨立(li)分層(ceng)。鋅(xin)(xin)(xin)層(ceng)較(jiao)薄(bo),鋅(xin)(xin)(xin)層(ceng)簡單(dan)附著在(zai)鋼(gang)管(guan)(guan)(guan)(guan)基體(ti)上,容(rong)易脫落。故(gu)其耐腐蝕性能差。在(zai)新建住宅中,禁(jin)止使用(yong)冷(leng)(leng)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)鋼(gang)管(guan)(guan)(guan)(guan)作為(wei)給水管(guan)(guan)(guan)(guan)。
