熱鍍鋅鋼管：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行酸洗，為了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。熱鍍鋅具有鍍層均勻，附著力強，使用壽命長等優(yōu)點。熱鍍鋅鋼管基體與熔融的鍍液發(fā)生復(fù)雜的物理、化學反鍍鋅鋼管應(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。 </p> <p> 冷鍍鋅鋼管：冷鍍鋅管就是電鍍鋅，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(chǎn)廠家，為了保證質(zhì)量，大多不采用電鍍鋅(冷鍍)。只有那些規(guī)模小、設(shè)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。目前建設(shè)部已正式下文，淘汰技術(shù)落后的冷鍍鋅管，今后不準用冷鍍鋅管作水、煤氣管。冷鍍鋅鋼管鍍鋅層是電鍍層，鋅層與鋼管基體**分層。鋅層較薄，鋅層簡單附著在鋼管基體上，容易脫落。故其耐腐蝕性能差。在新建住宅中，禁止使用冷鍍鋅鋼管作為給水管。 </p> <p> <br /> </p><p> 有一種流體管，其實就是經(jīng)過處理的高頻焊管，，其處理方法就是將原來的焊縫用**的設(shè)備或者刨掉或者磨掉，還有一種就是將焊管熱軋。 </p> <p> 1）凡是刨掉的或者磨掉的都會留下痕跡，有的還很明顯，有時用工具除銹后更明顯； </p> <p> 2）大家仔細觀察以下，20#鋼和Q235由于材質(zhì)不同，它們的銹也不同； </p> <p> 3）這種管子的廠家由于怕承擔責任，他們的質(zhì)量證明書上都是流體管而不敢說是流體用無縫鋼管； </p> <p> 4）賣這種管子的商家一般會要求按理論重量結(jié)算，大家都知道真正的國產(chǎn)無縫鋼管都是超出標準厚度的，一般是過磅； </p> <p> 5）還有就是探傷和做成分檢驗了，這兩個手段都有局限，因為探傷對經(jīng)過熱軋的焊管很難辨別，而現(xiàn)在河北有專門用20#鋼板做的焊管然后在加工，成分分析也就失去了意義。鍍鋅管鍍鋅角鋼鍍鋅方管現(xiàn)貨供應(yīng)規(guī)格齊全，還有其他可以選嗎！</p><div style="width:100%;text-align: center;"><img
