我國早期的管道建設主要采用的是不銹鋼無縫管，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(han)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(dou)無縫(feng)、包鋼(gang)等企業(ye)按(an)《一般無縫(feng)鋼(gang)管(guan)》（YB 231-1970）和后(hou)來的《輸(shu)送流體(ti)用(yong)無縫(feng)鋼(gang)管(guan)》（GB／T 8163-1987）標準，生產流體(ti)輸(shu)送用(yong)管(guan)，主要牌號：A3（A3F）、10、20、16Mn、Q235、Q295、Q345等，主要管(guan)徑：Φ159mm、ф219mm、φ273mm、Φ325mm、φ426mm、最(zui)大(da)管(guan)徑為Φ630mm。
