鍍鋅圓管分為冷鍍鋅圓管、熱鍍鋅圓管。冷鍍鋅圓管已被禁用，熱鍍鋅圓管還被提倡暫時能使用。鍍鋅圓管表面有熱浸鍍或電鍍鋅層的焊接鋼管。鍍鋅可增加鋼管的抗腐蝕能力，延長使用壽命。鍍鋅圓管的用途很廣，除作輸水、煤氣、油等一般低壓力流體的管線管外，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。盤龍區(qū)40鍍鋅圓管公司鍍鋅管鍍銅屬于連續(xù)電鍍，但電鍍設(shè)備不同。</p><div

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(nèi)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(nèi)壁滋生的細(xì)菌，銹蝕造成水中重金屬含量過高，嚴(yán)重危害人體的健康。六七十年代，國際上發(fā)達(dá)國家開始開發(fā)新型管材，并陸續(xù)禁用鍍鋅管。中國建設(shè)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。 </p> <p> <br /> </p> <p> <br /> </p>鋼材力學(xué)性能是保證鋼材終使用性能（機(jī)械性能）的重要指標(biāo)，它取決于鋼的化學(xué)成分和熱處理制度。在鋼管標(biāo)準(zhǔn)中，根據(jù)不同的使用要求，規(guī)定了拉伸性能（抗拉強(qiáng)度、屈服強(qiáng)度或屈服點、伸長率）以及硬度、韌性指標(biāo)，還有用戶要求的高、低溫性能等。 <p> 低壓流體輸送用鍍鋅焊接鋼管
