在工程設(she)計(ji)中，常遇(yu)到廠際管(guan)道（Pipeline between the Plants or District）的設(she)計(ji)，不同的國(guo)內外規范(fan)，設(she)計(ji)要求可(ke)能不同。
在GB 50160《石油(you)(you)化(hua)工企(qi)(qi)業設(she)計防(fang)火(huo)規(gui)范》中，廠(chang)際管(guan)(guan)道指(zhi)敷設(she)在石油(you)(you)化(hua)工企(qi)(qi)業、油(you)(you)庫、油(you)(you)氣(qi)碼(ma)頭等(deng)不(bu)同圍墻界(jie)區之間且通過公共區域、長(chang)度小于(yu)等(deng)于(yu)30km的(de)輸油(you)(you)輸氣(qi)管(guan)(guan)道。
在(zai)GB/T 51359《石(shi)(shi)(shi)油化(hua)(hua)(hua)(hua)(hua)工(gong)(gong)(gong)廠際管(guan)道(dao)工(gong)(gong)(gong)程(cheng)技術(shu)標準》規范中，廠際管(guan)道(dao)指石(shi)(shi)(shi)油化(hua)(hua)(hua)(hua)(hua)工(gong)(gong)(gong)及(ji)煤(mei)化(hua)(hua)(hua)(hua)(hua)工(gong)(gong)(gong)企業(ye)、石(shi)(shi)(shi)油庫、石(shi)(shi)(shi)油化(hua)(hua)(hua)(hua)(hua)工(gong)(gong)(gong)碼頭等相(xiang)互間的輸送可(ke)燃氣體、液化(hua)(hua)(hua)(hua)(hua)烴和可(ke)燃液體管(guan)道(dao)（石(shi)(shi)(shi)油化(hua)(hua)(hua)(hua)(hua)工(gong)(gong)(gong)園區除外(wai)）。其特征是(shi)敷設在(zai)石(shi)(shi)(shi)油化(hua)(hua)(hua)(hua)(hua)工(gong)(gong)(gong)及(ji)煤(mei)化(hua)(hua)(hua)(hua)(hua)工(gong)(gong)(gong)企業(ye)、石(shi)(shi)(shi)油庫、石(shi)(shi)(shi)油化(hua)(hua)(hua)(hua)(hua)工(gong)(gong)(gong)碼頭等圍墻或(huo)用地邊界(jie)線之間且(qie)通(tong)過公共區域，長度小于或(huo)等于30km。
廠際(ji)管(guan)(guan)道(dao)的(de)特點是企業(ye)圍墻或用(yong)地邊界線之間、通(tong)(tong)過公共區域(yu)，長(chang)(chang)度(du)≤30km。廠際(ji)管(guan)(guan)道(dao)長(chang)(chang)度(du)限(xian)定在(zai)30km，考慮了與長(chang)(chang)距(ju)離輸(shu)油(you)管(guan)(guan)道(dao)的(de)兩(liang)切斷(duan)閥間距(ju)相協調。一(yi)般情況下，長(chang)(chang)距(ju)離輸(shu)送(song)油(you)氣(qi)管(guan)(guan)道(dao)長(chang)(chang)度(du)在(zai)50km以上，有(you)中間泵站(zhan)或加壓(ya)站(zhan)等特征，而廠際(ji)管(guan)(guan)道(dao)通(tong)(tong)常是多條(tiao)管(guan)(guan)道(dao)并(bing)列敷設，無中間泵站(zhan)或加壓(ya)站(zhan)，這一(yi)長(chang)(chang)度(du)也(ye)基本涵蓋了目前石油(you)化工企業(ye)不同圍墻或用(yong)地邊界之間的(de)油(you)氣(qi)管(guan)(guan)道(dao)長(chang)(chang)度(du)。廠際(ji)管(guan)(guan)道(dao)不屬于地區輸(shu)油(you)（輸(shu)氣(qi)）管(guan)(guan)道(dao)，也(ye)不包括石油(you)化工園區內(nei)公用(yong)的(de)輸(shu)送(song)可(ke)燃氣(qi)體、液化烴和(he)可(ke)燃液體的(de)管(guan)(guan)道(dao)。一(yi)般定義廠際(ji)管(guan)(guan)道(dao)為GC類。
