我國早期的管道建設主要采用的是不銹鋼無(wu)縫管，但口徑受到了限制。隨著焊管生產技術的發展和焊管質量的提高以及不銹鋼焊管的直徑可以做得更大，焊管很快就替代了不銹鋼無縫管，成為管道建設的主角。隨著管道建設向大型化、高輸送量發展，中大口徑的管道基本采用了焊管，90年代以來，我國油氣管道的主干線全部被焊管所壟斷，不銹鋼無縫管主要用于支線管、集輸管線、海底管線和城市的管網。

  70-80年代成都無(wu)(wu)縫、包鋼等企業(ye)按《一(yi)般(ban)無(wu)(wu)縫鋼管(guan)》（YB 231-1970）和后來的《輸(shu)送流(liu)體用(yong)無(wu)(wu)縫鋼管(guan)》（GB／T 8163-1987）標準，生(sheng)產流(liu)體輸(shu)送用(yong)管(guan)，主(zhu)要牌號：A3（A3F）、10、20、16Mn、Q235、Q295、Q345等，主(zhu)要管(guan)徑：Φ159mm、ф219mm、φ273mm、Φ325mm、φ426mm、最大管(guan)徑為Φ630mm。
