,是一種大家認可的叫法,通過其可以很好的去找到相應的外徑和壁厚,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，在設計圖紙中一般采用公稱直徑來表示，公稱直徑是為了設計制造和維修的方便人為地規(guī)定的一種標準，也叫公稱通徑，是管子（或者管件）的規(guī)格名稱。 </p> <p> 標準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。 </p><p style="text-indent:25px"><p>鍍鋅圓管的分類有哪些？<p>一、熱鍍鋅管。是使熔融金屬與鐵基體反應而產(chǎn)生合金層，從而使基體和鍍層二者相結合。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。北方大部分工藝采用鍍鋅帶直接卷管補鋅工藝。<p>二、冷鍍鋅管。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(chǎn)廠家，為了保證質量，大多不采用電鍍鋅（冷鍍）。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。今后不準用冷鍍鋅管作水、煤氣管。<p>三、熱鍍鋅鋼管。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。如何控制鍍鋅圓管的焊接過程？</p><div

2.冷鍍鋅層均勻，厚度很薄，熱鍍鋅層較厚，厚度不均勻。 3.冷鍍外觀光亮，熱鍍顏色較暗。 4.冷鍍層因為較薄，耐蝕性較差；熱鍍層因為較厚是冷鍍鋅的幾十倍，而且與基體金屬形成滲入層，耐蝕性好。 5.冷鍍鋅圓管看上去表面亮一些，光滑平整；熱鍍鋅外表沒有冷鍍鋅細膩光亮，熱鍍鋅圓管表面看上去好像有一些高低不平的凹凸，而且表面不發(fā)亮，不太反光。6.熱鍍鋅一般鍍層比較厚，這是熱鍍鋅的工藝所具備的，可以用刀或者刃器刮出鋅，像焊錫層一樣。冷鍍鋅鍍層一般比較薄，可以用刀或者刃器難以（或者無法）刮出鋅。鍍鋅圓管廠家報價，云南贛僑貿(mào)易供應。昆明官渡區(qū)6分鍍鋅圓管市場行情</p><p

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。冷鍍鋅鋼管鋅層是電鍍層，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> 鍍鋅鋼管的用途 </p> <p> 常說的鍍鋅管，鍍鋅管的用途現(xiàn)在煤氣、暖氣用的那種鐵管也是鍍鋅管，鍍鋅管作為水管，使用幾年后，管內產(chǎn)生大量銹垢，流出的黃水不僅污染潔具，而且夾雜著不光滑內壁滋生的細菌，銹蝕造成水中重金屬含量過高，嚴重危害人體的健康。六七十年代，國際上發(fā)達國家開始開發(fā)新型管材，并陸續(xù)禁用鍍鋅管。中國建設部等四部委也發(fā)文明確從二000年起禁用鍍鋅管，目前新建小區(qū)的冷水管已經(jīng)很少使用鍍鋅管了，有些小區(qū)的熱水管使用的是鍍鋅管。
