關于鍍鋅管的分類有哪些?
1、熱鍍鋅(xin)管。是(shi)使(shi)熔融(rong)金(jin)屬與(yu)鐵基(ji)體反應而產生合(he)金(jin)層(ceng)(ceng),從而使(shi)基(ji)體和(he)鍍層(ceng)(ceng)二者相(xiang)結合(he)。熱鍍鋅(xin)是(shi)先將鋼管進(jin)行酸洗,為(wei)了去除(chu)鋼管表(biao)面的(de)氧(yang)化鐵,酸洗后,通(tong)過(guo)氯(lv)(lv)(lv)化銨(an)或氯(lv)(lv)(lv)化鋅(xin)水(shui)溶液或氯(lv)(lv)(lv)化銨(an)和(he)氯(lv)(lv)(lv)化鋅(xin)混合(he)水(shui)溶液槽(cao)中進(jin)行清(qing)洗,然后送(song)入熱浸鍍槽(cao)中。熱鍍鋅(xin)具有鍍層(ceng)(ceng)均勻,附(fu)著力強,使(shi)用壽(shou)命長等(deng)優點。北(bei)方大部(bu)分工藝采用鍍鋅(xin)帶直接(jie)卷管補鋅(xin)工藝。
2、冷鍍(du)鋅(xin)管(guan)(guan)。冷鍍(du)鋅(xin)就是(shi)電鍍(du)鋅(xin),鍍(du)鋅(xin)量很少,只有10-50g/m2,其本身(shen)的(de)耐腐蝕性(xing)比熱(re)鍍(du)鋅(xin)管(guan)(guan)相差很多。正(zheng)規的(de)鍍(du)鋅(xin)管(guan)(guan)生產(chan)廠家,為了保證質(zhi)量,大多不采(cai)用電鍍(du)鋅(xin)(冷鍍(du))。只有那(nei)些規模(mo)小、設備陳舊的(de)小企業采(cai)用電鍍(du)鋅(xin),當(dang)然他們的(de)價格也相對便宜一(yi)些。今后(hou)不準用冷鍍(du)鋅(xin)管(guan)(guan)作(zuo)水、煤氣管(guan)(guan)。

3、熱鍍鋅鋼(gang)管。鋼(gang)管基體(ti)與熔融(rong)的(de)鍍液發(fa)生(sheng)復雜的(de)物理、化學(xue)反應,形成耐腐(fu)蝕的(de)結構(gou)緊密的(de)鋅一(yi)鐵合金層。合金層與純鋅層、鋼(gang)管基體(ti)融(rong)為一(yi)體(ti)。故其耐腐(fu)蝕能力強。
4、冷(leng)鍍(du)(du)鋅鋼(gang)管。鋅層是電鍍(du)(du)層,鋅層與鋼(gang)管基(ji)體獨立分層。鋅層較薄,鋅層簡單附著在鋼(gang)管基(ji)體上,容易(yi)脫落。故其(qi)耐腐蝕(shi)性能差(cha)。在新建住宅中(zhong),禁止使(shi)用冷(leng)鍍(du)(du)鋅鋼(gang)管作(zuo)為給水管。
鍍鋅(xin)管的(de)規格(ge)都有什(shen)么
為提高(gao)鋼(gang)(gang)(gang)管(guan)(guan)(guan)(guan)(guan)的耐腐(fu)蝕性能(neng),對一(yi)般鋼(gang)(gang)(gang)管(guan)(guan)(guan)(guan)(guan)進行(xing)鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)。鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)管(guan)(guan)(guan)(guan)(guan)分熱鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)和電鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)兩(liang)種(zhong),熱鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)層厚,電鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)成(cheng)本低,表面(mian)不是(shi)很光滑。吹氧焊(han)管(guan)(guan)(guan)(guan)(guan):用(yong)作煉鋼(gang)(gang)(gang)吹氧用(yong)管(guan)(guan)(guan)(guan)(guan),一(yi)般用(yong)小口徑的焊(han)接鋼(gang)(gang)(gang)管(guan)(guan)(guan)(guan)(guan),規格由3/8-2寸八種(zhong)。用(yong)08、10、15、20或者195-Q235的鋼(gang)(gang)(gang)帶制作成(cheng)的,為了防腐(fu)蝕,有(you)的要(yao)進行(xing)有(you)效滲鋁(lv)處理。老(lao)房子大(da)部分是(shi)用(yong)的都是(shi)鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)管(guan)(guan)(guan)(guan)(guan),現在煤氣(qi)(qi)、暖氣(qi)(qi)用(yong)的那種(zhong)鐵管(guan)(guan)(guan)(guan)(guan)也是(shi)鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)管(guan)(guan)(guan)(guan)(guan)。
