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(bu)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)縫(feng)、包鋼等企業按《一般(ban)無(wu)縫(feng)鋼管》（YB 231-1970）和后來的《輸送流(liu)體用(yong)(yong)無(wu)縫(feng)鋼管》（GB／T 8163-1987）標(biao)準(zhun)，生產流(liu)體輸送用(yong)(yong)管，主要牌(pai)號(hao)：A3（A3F）、10、20、16Mn、Q235、Q295、Q345等，主要管徑：Φ159mm、ф219mm、φ273mm、Φ325mm、φ426mm、最大(da)管徑為Φ630mm。
