關于鍍鋅鋼管分為冷鍍鋅鋼管和熱鍍鋅鋼管，鍍鋅管被普(pu)遍應用(yong)，除水、氣、油等普(pu)通高(gao)壓流體(ti)管(guan)(guan)(guan)線(xian)外，還用(yong)于煤油工業，特別是(shi)遠洋油田的油田油井管(guan)(guan)(guan)道、管(guan)(guan)(guan)道、冷凝冷卻器、煤蒸餾油交換管(guan)(guan)(guan)，以及(ji)橋管(guan)(guan)(guan)樁、礦井管(guan)(guan)(guan)支持(chi)管(guan)(guan)(guan)。鍍鋅(xin)(xin)鋼(gang)管(guan)(guan)(guan)有熱浸層或鍍鋅(xin)(xin)層的焊接鋼(gang)管(guan)(guan)(guan)，鍍鋅(xin)(xin)提(ti)高(gao)了鋼(gang)管(guan)(guan)(guan)的耐腐蝕性，延長了應用(yong)壽命。

人(ren)們常說(shuo)鍍鋅(xin)鋼管(guan)(guan)用(yong)于煤氣和取暖，鍍鋅(xin)鋼管(guan)(guan)作為(wei)一種(zhong)水管(guan)(guan)，應用(yong)幾年后會(hui)發現少(shao)量(liang)的鐵(tie)銹。不但傳(chuan)染(ran)衛生(sheng)(sheng)潔具，并(bing)且含有細菌生(sheng)(sheng)長在不光滑(hua)的內壁上(shang)，鐵(tie)銹致使(shi)水體中重金(jin)屬含量(liang)高，危(wei)害人(ren)類健康。

熱(re)鍍(du)(du)(du)鋅(xin)管(guan)(guan)是將熔融(rong)的(de)(de)(de)金屬與(yu)鐵合金層(ceng)(ceng)相融(rong)，使基體(ti)與(yu)涂層(ceng)(ceng)互(hu)相感化(hua)(hua)。熱(re)浸鍍(du)(du)(du)鋅(xin)是將鋼(gang)管(guan)(guan)浸入(ru)酸中(zhong)(zhong)，為了去(qu)除鋼(gang)管(guan)(guan)外表的(de)(de)(de)氧化(hua)(hua)鐵，鋼(gang)管(guan)(guan)酸洗后(hou)(hou)，用水溶液氯(lv)化(hua)(hua)銨(an)或(huo)氯(lv)化(hua)(hua)鋅(xin)或(huo)氯(lv)化(hua)(hua)銨(an)和(he)氯(lv)化(hua)(hua)鋅(xin)的(de)(de)(de)混(hun)合，而后(hou)(hou)放入(ru)熱(re)浸鍍(du)(du)(du)槽中(zhong)(zhong)。熱(re)鍍(du)(du)(du)鋅(xin)涂層(ceng)(ceng)勻稱，附著力強(qiang)，應用壽命長。熱(re)鍍(du)(du)(du)鋅(xin)鋼(gang)管(guan)(guan)基體(ti)與(yu)熔融(rong)的(de)(de)(de)鍍(du)(du)(du)液發(fa)生復(fu)雜的(de)(de)(de)物理、化(hua)(hua)學反應進而構成(cheng)了布局致密的(de)(de)(de)耐蝕鋅(xin)鐵合金層(ceng)(ceng)。合金層(ceng)(ceng)與(yu)純鋅(xin)層(ceng)(ceng)和(he)鋼(gang)管(guan)(guan)基體(ti)融(rong) 合在一起，所以它的(de)(de)(de)耐腐(fu)蝕性(xing)異常強(qiang)。

冷(leng)鍍(du)(du)(du)(du)鋅(xin)(xin)管(guan)(guan)(guan)是用(yong)電(dian)(dian)鍍(du)(du)(du)(du)鋅(xin)(xin)的(de)，鍍(du)(du)(du)(du)鋅(xin)(xin)量(liang)很少，耐腐(fu)蝕(shi)功能和(he)熱鍍(du)(du)(du)(du)鋅(xin)(xin)管(guan)(guan)(guan)差異很大(da)。為(wei)了保障品(pin)質，大(da)部分(fen)正規的(de)鍍(du)(du)(du)(du)鋅(xin)(xin)管(guan)(guan)(guan)出產(chan)廠家(jia)都不應用(yong)電(dian)(dian)鍍(du)(du)(du)(du)鋅(xin)(xin)（冷(leng)鍍(du)(du)(du)(du)）。那些范(fan)圍小、設(she)置裝備擺設(she)陳(chen)腐(fu)的(de)小企業由于價錢相(xiang)對便宜，會使(shi)用(yong)電(dian)(dian)鍍(du)(du)(du)(du)鋅(xin)(xin)。冷(leng)鍍(du)(du)(du)(du)鋅(xin)(xin)鋼(gang)管(guan)(guan)(guan)的(de)鍍(du)(du)(du)(du)鋅(xin)(xin)層(ceng)(ceng)為(wei)電(dian)(dian)鍍(du)(du)(du)(du)層(ceng)(ceng)，鋅(xin)(xin)層(ceng)(ceng)與鋼(gang)管(guan)(guan)(guan)基體獨立分(fen)層(ceng)(ceng)。鋅(xin)(xin)層(ceng)(ceng)較薄(bo)，簡(jian)略附著在鋼(gang)管(guan)(guan)(guan)上，容易脫落。所(suo)以(yi)，其(qi)耐腐(fu)蝕(shi)性差。新建屋宇(yu)，禁止使(shi)用(yong)冷(leng)鍍(du)(du)(du)(du)鋅(xin)(xin)鋼(gang)管(guan)(guan)(guan)作為(wei)供水管(guan)(guan)(guan)。
