在工程設計中，常遇到(dao)廠際管(guan)道（Pipeline between the Plants or District）的(de)設計，不同(tong)的(de)國內外(wai)規范，設計要求可能不同(tong)。

  在GB 50160《石油(you)化工企(qi)業(ye)設計(ji)防火規(gui)范》中，廠際管道指敷(fu)設在石油(you)化工企(qi)業(ye)、油(you)庫、油(you)氣碼頭等不同圍墻界區之間且通過公共區域、長(chang)度小于(yu)等于(yu)30km的輸油(you)輸氣管道。

  在GB/T 51359《石(shi)(shi)(shi)油(you)化(hua)工(gong)(gong)(gong)廠際管道工(gong)(gong)(gong)程(cheng)技術標準》規范中，廠際管道指石(shi)(shi)(shi)油(you)化(hua)工(gong)(gong)(gong)及煤化(hua)工(gong)(gong)(gong)企業、石(shi)(shi)(shi)油(you)庫、石(shi)(shi)(shi)油(you)化(hua)工(gong)(gong)(gong)碼頭等相互間(jian)的輸送可燃(ran)氣體、液化(hua)烴和(he)可燃(ran)液體管道（石(shi)(shi)(shi)油(you)化(hua)工(gong)(gong)(gong)園區(qu)(qu)除外(wai)）。其(qi)特征(zheng)是敷設在石(shi)(shi)(shi)油(you)化(hua)工(gong)(gong)(gong)及煤化(hua)工(gong)(gong)(gong)企業、石(shi)(shi)(shi)油(you)庫、石(shi)(shi)(shi)油(you)化(hua)工(gong)(gong)(gong)碼頭等圍墻或用地邊界線之間(jian)且通過公(gong)共區(qu)(qu)域，長度小于(yu)或等于(yu)30km。

  廠(chang)(chang)際(ji)管(guan)(guan)(guan)道(dao)的(de)特點是企業(ye)(ye)圍(wei)墻或(huo)用地邊界線之間(jian)(jian)、通過公共區域，長(chang)度(du)≤30km。廠(chang)(chang)際(ji)管(guan)(guan)(guan)道(dao)長(chang)度(du)限定(ding)在30km，考(kao)慮了與長(chang)距離輸(shu)(shu)油(you)(you)(you)(you)管(guan)(guan)(guan)道(dao)的(de)兩切斷閥間(jian)(jian)距相(xiang)協調。一般(ban)情(qing)況下，長(chang)距離輸(shu)(shu)送(song)油(you)(you)(you)(you)氣管(guan)(guan)(guan)道(dao)長(chang)度(du)在50km以上，有(you)中(zhong)(zhong)間(jian)(jian)泵(beng)站(zhan)或(huo)加壓(ya)站(zhan)等特征，而廠(chang)(chang)際(ji)管(guan)(guan)(guan)道(dao)通常是多條管(guan)(guan)(guan)道(dao)并列敷(fu)設，無中(zhong)(zhong)間(jian)(jian)泵(beng)站(zhan)或(huo)加壓(ya)站(zhan)，這一長(chang)度(du)也基(ji)本涵(han)蓋了目前石(shi)油(you)(you)(you)(you)化工企業(ye)(ye)不同圍(wei)墻或(huo)用地邊界之間(jian)(jian)的(de)油(you)(you)(you)(you)氣管(guan)(guan)(guan)道(dao)長(chang)度(du)。廠(chang)(chang)際(ji)管(guan)(guan)(guan)道(dao)不屬(shu)于(yu)地區輸(shu)(shu)油(you)(you)(you)(you)（輸(shu)(shu)氣）管(guan)(guan)(guan)道(dao)，也不包括石(shi)油(you)(you)(you)(you)化工園區內公用的(de)輸(shu)(shu)送(song)可燃氣體、液(ye)化烴和(he)可燃液(ye)體的(de)管(guan)(guan)(guan)道(dao)。一般(ban)定(ding)義(yi)廠(chang)(chang)際(ji)管(guan)(guan)(guan)道(dao)為GC類。
