鍍鋅鋼管，分熱鍍鋅和冷鍍鋅兩種，熱鍍鋅鍍鋅層厚，具有鍍層均勻，附著力強(qiáng)，使用壽命長(zhǎng)等優(yōu)點(diǎn)。冷鍍鋅成本低，表面不是很光滑，其本身的耐腐蝕性比熱鍍鋅管差很多。熱鍍鋅管是使熔融金屬與鐵基體反應(yīng)而產(chǎn)生合金層，從而使基體和鍍層二者相結(jié)合。熱鍍鋅是先將鋼管進(jìn)行酸洗，為了去除鋼管表面的氧化鐵，酸洗后，通過(guò)氯化銨或氯化鋅水溶液或氯化銨和氯化鋅混合水溶液槽中進(jìn)行清洗，然后送入熱浸鍍槽中。熱鍍鋅具有鍍層均勻，附著力強(qiáng)，使用壽命長(zhǎng)等優(yōu)點(diǎn)。北方大部分工藝采用鍍鋅帶直接卷管補(bǔ)鋅工藝。熱鍍鋅具有鍍層均勻，附著力強(qiáng)，使用壽命長(zhǎng)等優(yōu)點(diǎn)。熱鍍鋅鋼管基體與熔融的鍍液發(fā)生復(fù)雜的物理、化學(xué)反應(yīng)，形成耐腐蝕的結(jié)構(gòu)緊密的鋅一鐵合金層。合金層與純鋅層、鋼管基體融為一體。故其耐腐蝕能力強(qiáng)。冷鍍鋅管冷鍍鋅就是電鍍鋅，鍍鋅量少，只有10－50g/m2，其本身的耐腐蝕性比熱鍍鋅管差很多。鍍鋅管的用途很廣，除作輸水、煤氣、油等一般低壓力流體的管線(xiàn)管外，還用作石油工業(yè)特別是海洋油田的油井管、輸油管，化工焦化設(shè)備的油加熱器、冷凝冷卻器、煤餾洗油交換器用管，以及棧橋管樁、礦山坑道的支撐架用管等。確認(rèn)卡箍件的弧形完全嵌入外殼的凹槽，均勻擰緊螺栓，直到外殼表面和墊圈套接觸嚴(yán)密。</p><div
