冷鍍鋅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。建設(shè)部已正式下文，淘汰技術(shù)落后的冷鍍鋅管，不準用冷鍍鋅管作水、煤氣管。冷鍍鋅鋼管鍍鋅層是電鍍層，鋅層與鋼管基體獨自分層。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。蘇州消防**管公司鋼塑復合管中的塑料一般是高密度聚乙烯（HDPE）。</p><div

無縫鋼管按生產(chǎn)方法可分為：熱軋無縫管、冷拔管、精密鋼管、熱擴管、冷旋壓管和擠壓管等。 </p> <p> 無縫鋼管用優(yōu)異碳素鋼或合金鋼制成，有熱軋、冷軋（拔）之分。 </p> <p> 2.焊接鋼管因其焊接工藝不同而分為爐焊管、電焊（電阻焊）管和自動電弧焊管，因其焊接形式的不同分為直縫焊管和螺旋焊管兩種，因其端部形狀又分為圓形焊管和異型（方、扁等）焊管。 </p> <p> 焊接鋼管是由卷成管形的鋼板以對縫或螺旋縫焊接而成，在制造方法上，又分為低壓流體輸送用焊接鋼管、螺旋縫電焊鋼管、直接卷焊鋼管、電焊管等。無縫鋼管可用于各種行業(yè)的液體氣壓管道和氣體管道等。焊接管道可用于輸水管道、煤氣管道、暖氣管道、電器管道等。鋼塑管的性質(zhì)有哪些？湖州鋼塑管哪里有</p><p
