焊接鋼管也稱焊管，是用鋼板或鋼帶經過卷曲成型后焊接制成的鋼管鋼管。焊接鋼管生產工藝簡單，生產效率高，品種規格多，設備資少，但一般強度低于無縫鋼管。20世紀30年代以來，隨著優質帶鋼連軋生產的迅速發展以及焊接和檢驗技術的進步，吹氧管廠家焊縫質量不斷提高，焊接鋼管的品種規格日益增多，并在越來越多的領域代替了無縫鋼管。焊管的應用范圍：產品廣泛應用于自來水工程、石化工業、化學工業、電力工業、農業灌溉、城市建設，是我國開發的二十個重點產品之一。作液體輸送用：給水、排水。作氣體輸送用：煤氣、蒸氣、液化石油氣。作結構用：作打樁管、作橋梁；碼頭、道路、建筑結構用管等。</strong>

焊接鋼管采用的坯料是鋼板或帶鋼，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。焊管因其材質和用途不同而分為如下若干品種： GB/T3091-2008（低壓流體輸送用焊接鋼管）：主要用于輸送水、煤氣、空氣、油和取暖熱水或蒸汽等一般較低壓力流體和其它用途管。其代表材質為：<a href="www.n7203.cn" target="_blank">Q235A級鋼。 GB/T14291-2006</a>（礦用流體輸送焊接鋼管）：主要用于礦山壓風、排水、軸放瓦斯用直縫焊接鋼管。其代表材質Q235A、B級鋼。 GB/T12770-2002（機械結構用不銹鋼焊接鋼管）：主要用于機械、汽車、自行車、家具、賓館和飯店裝飾及其他機械部件與結構件。其代表材質0Cr13、1Cr17、00Cr19Ni11、1Cr18Ni9、0Cr18Ni11Nb等。 GB/T12771-1991（流體輸送用不銹鋼焊接鋼管）：主要用于輸送低壓腐蝕性介質。代表材質為0Cr13、0Cr19Ni9、00Cr19Ni11、00Cr17、0Cr18Ni11Nb、0017Cr17Ni14Mo2等。</strong><br /></td> </tr> <tr> <td align="left" style="border-top:1px #CCCCCC dotted;
