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)，使用壽命長等優(yōu)點。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)。 </p><p> 鍍鋅圓管是按內(nèi)徑還是外徑計算價格呢？公稱直徑,有別于外徑和內(nèi)徑 ,是一種大家認(rèn)可的叫法,通過其可以很好的去找到相應(yīng)的外徑和壁厚,只要其公稱直徑相同,就可用相同公稱直徑的管件相連接,具有通用性和互換性。一般來說，管子的直徑可分為外徑、內(nèi)徑、公稱直徑。管材為無縫鋼管的管子的外徑用字母D來表示，其后附加外直徑的尺寸和壁厚，例如外徑為108的無縫鋼管，壁厚為5MM，用D108*5表示。 </p> <p> 塑料管也用外徑表示，如De63,其他如鋼筋混凝土管、鑄鐵管、鍍鋅鋼管等采用DN表示，在設(shè)計圖紙中一般采用公稱直徑來表示，公稱直徑是為了設(shè)計制造和維修的方便人為地規(guī)定的一種標(biāo)準(zhǔn)，也叫公稱通徑，是管子（或者管件）的規(guī)格名稱。 </p> <p> 標(biāo)準(zhǔn)中稱此外徑與厚度為公稱外徑與公稱厚度。輸送流體用無縫鋼管和一般用途無縫鋼管分熱軋管和冷拔管兩種。冷拔管的外徑為200mm；熱軋管的外徑為630mm。 </p> <p> 在管道工程中，管徑過57mm時，常采用熱軋管。管徑在57mm以內(nèi)常選用冷拔管。DN2000鞍座是指支承DN2000mm容器的鞍式支座。還有一些零部件的公稱直徑是與它相配的管子公稱直徑表示的。如管法蘭，DN200管法蘭是指連接DN200mm管子的管法蘭。云南鍍鋅圓管報價，云南贛僑貿(mào)易供應(yīng)。</p><div style="width:100%;text-align:
