在工程(cheng)設(she)計(ji)中，常遇(yu)到廠際管道（Pipeline between the Plants or District）的(de)設(she)計(ji)，不(bu)同的(de)國(guo)內外(wai)規(gui)范，設(she)計(ji)要求可能不(bu)同。

  在GB 50160《石油(you)(you)化(hua)工企業設(she)計防火規范(fan)》中，廠際(ji)管道指敷(fu)設(she)在石油(you)(you)化(hua)工企業、油(you)(you)庫、油(you)(you)氣(qi)(qi)碼頭等(deng)(deng)不同圍墻界(jie)區之(zhi)間且通過公共區域、長度小(xiao)于(yu)(yu)等(deng)(deng)于(yu)(yu)30km的輸(shu)油(you)(you)輸(shu)氣(qi)(qi)管道。

  在(zai)GB/T 51359《石(shi)(shi)(shi)(shi)油(you)化(hua)(hua)(hua)(hua)工(gong)(gong)廠際管道(dao)(dao)工(gong)(gong)程技術標準》規范中，廠際管道(dao)(dao)指石(shi)(shi)(shi)(shi)油(you)化(hua)(hua)(hua)(hua)工(gong)(gong)及(ji)煤(mei)(mei)化(hua)(hua)(hua)(hua)工(gong)(gong)企(qi)業、石(shi)(shi)(shi)(shi)油(you)庫(ku)、石(shi)(shi)(shi)(shi)油(you)化(hua)(hua)(hua)(hua)工(gong)(gong)碼頭(tou)等相(xiang)互間的輸送可燃(ran)氣(qi)體、液(ye)化(hua)(hua)(hua)(hua)烴和可燃(ran)液(ye)體管道(dao)(dao)（石(shi)(shi)(shi)(shi)油(you)化(hua)(hua)(hua)(hua)工(gong)(gong)園區(qu)除外）。其特征(zheng)是敷設在(zai)石(shi)(shi)(shi)(shi)油(you)化(hua)(hua)(hua)(hua)工(gong)(gong)及(ji)煤(mei)(mei)化(hua)(hua)(hua)(hua)工(gong)(gong)企(qi)業、石(shi)(shi)(shi)(shi)油(you)庫(ku)、石(shi)(shi)(shi)(shi)油(you)化(hua)(hua)(hua)(hua)工(gong)(gong)碼頭(tou)等圍墻或(huo)(huo)用地邊界線(xian)之間且(qie)通過公共(gong)區(qu)域，長度小于或(huo)(huo)等于30km。

  廠(chang)(chang)際(ji)管(guan)道的(de)特(te)點是企業圍(wei)墻或用(yong)地邊界線之間(jian)(jian)、通過公共區(qu)域(yu)，長(chang)度(du)(du)≤30km。廠(chang)(chang)際(ji)管(guan)道長(chang)度(du)(du)限定在(zai)30km，考慮了與長(chang)距(ju)離輸(shu)油(you)管(guan)道的(de)兩切斷閥間(jian)(jian)距(ju)相協調。一般情況下(xia)，長(chang)距(ju)離輸(shu)送油(you)氣(qi)管(guan)道長(chang)度(du)(du)在(zai)50km以上，有中間(jian)(jian)泵站(zhan)或加(jia)壓站(zhan)等特(te)征，而(er)廠(chang)(chang)際(ji)管(guan)道通常(chang)是多條管(guan)道并列(lie)敷設(she)，無中間(jian)(jian)泵站(zhan)或加(jia)壓站(zhan)，這一長(chang)度(du)(du)也(ye)基本涵蓋了目前石油(you)化(hua)工企業不(bu)同圍(wei)墻或用(yong)地邊界之間(jian)(jian)的(de)油(you)氣(qi)管(guan)道長(chang)度(du)(du)。廠(chang)(chang)際(ji)管(guan)道不(bu)屬于地區(qu)輸(shu)油(you)（輸(shu)氣(qi)）管(guan)道，也(ye)不(bu)包括石油(you)化(hua)工園(yuan)區(qu)內公用(yong)的(de)輸(shu)送可(ke)燃(ran)氣(qi)體(ti)、液(ye)(ye)化(hua)烴和可(ke)燃(ran)液(ye)(ye)體(ti)的(de)管(guan)道。一般定義廠(chang)(chang)際(ji)管(guan)道為GC類。
