用來去除鋼管表面的氧化鐵，酸洗后，通過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行清洗，然后送入熱浸鍍槽中。熱鍍鋅鋼管是鋼管基體與熔融的鍍液發(fā)生復雜的物理、化學反應，形成耐腐蝕的結構緊密的鋅鐵合金層。合金層與純鋅層、鋼管基體融為一體，因此熱鍍鋅鋼管具有鍍層均勻、附著力強、使用壽命長等優(yōu)點。2、冷鍍鋅管/冷鍍鋅鋼管冷鍍鋅就是電鍍鋅，鍍鋅量很少，只有10-50g/m2，其本身的耐腐蝕性比熱鍍鋅管相差很多。正規(guī)的鍍鋅管生產廠家，為了保證質量，大多不采用電鍍鋅(冷鍍鋅)。只有那些規(guī)模小、設備陳舊的小企業(yè)采用電鍍鋅，當然他們的價格也相對便宜一些。二、鍍鋅管的生產工藝流程鍍鋅鋼管的生產工藝屬于各生產廠家的機密，因此只能提供大致工藝流程：a.圓鋼準備;b.加熱;c.熱軋穿孔;d.切頭;e.酸洗;f.修磨;g.潤滑;h.冷軋加工;i.脫脂;j.固溶熱處理;k.矯直;l.切管;m.酸洗;n.成品檢驗。三、鍍鋅管的技術要求與標1、牌號和化學成分鍍鋅管鍍鋅鋼管用鋼的牌號和化學成分應符合GB-3092所規(guī)定的黑管用鋼的牌號和化學成分。2、鍍鋅管的制造方法鍍鋅管的制造方法(爐焊或電焊)由制造廠選擇。鍍鋅多采用熱浸鍍鋅法。3，安徽不銹鋼鍍鋅鋼管定制、鍍鋅管的螺紋及管接頭，安徽不銹鋼鍍鋅鋼管定制，安徽不銹鋼鍍鋅鋼管定制。操作設置在立柱頂部的手輪，轉動手輪緩慢向下，在鉆頭與鋼管接觸處添加適量潤滑劑完成鉆頭在鋼管上開孔。安徽不銹鋼鍍鋅鋼管定制</p><div
