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(guan)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(dai)成(cheng)都無(wu)縫、包鋼等企(qi)業按《一般(ban)無(wu)縫鋼管》（YB 231-1970）和后來的《輸送流體用(yong)無(wu)縫鋼管》（GB／T 8163-1987）標準，生產流體輸送用(yong)管，主要(yao)牌號：A3（A3F）、10、20、16Mn、Q235、Q295、Q345等，主要(yao)管徑(jing)(jing)：Φ159mm、ф219mm、φ273mm、Φ325mm、φ426mm、最大管徑(jing)(jing)為Φ630mm。
