按照TSG R1001《壓(ya)力(li)(li)(li)容器壓(ya)力(li)(li)(li)管(guan)(guan)(guan)道設計許可規(gui)則》2008版(ban)的定義，壓(ya)力(li)(li)(li)管(guan)(guan)(guan)道分(fen)為(wei)GA類(lei)(lei)長(chang)輸管(guan)(guan)(guan)道、GB類(lei)(lei)公(gong)(gong)用(yong)管(guan)(guan)(guan)道、GC類(lei)(lei)工業管(guan)(guan)(guan)道及GD類(lei)(lei)動力(li)(li)(li)管(guan)(guan)(guan)道。據2014年(nian)公(gong)(gong)布施行(xing)的《特種設備目錄(lu)》，壓(ya)力(li)(li)(li)管(guan)(guan)(guan)道分(fen)類(lei)(lei)變為(wei)：長(chang)輸管(guan)(guan)(guan)道（輸油管(guan)(guan)(guan)道、輸氣管(guan)(guan)(guan)道），公(gong)(gong)用(yong)管(guan)(guan)(guan)道（燃氣管(guan)(guan)(guan)道、熱力(li)(li)(li)管(guan)(guan)(guan)道），工業管(guan)(guan)(guan)道（工藝(yi)管(guan)(guan)(guan)道、動力(li)(li)(li)管(guan)(guan)(guan)道、制(zhi)冷(leng)管(guan)(guan)(guan)道），TSG R1001升版(ban)后也會按照新的壓(ya)力(li)(li)(li)管(guan)(guan)(guan)道分(fen)級（類(lei)(lei)）。
