在工程設計(ji)中，常(chang)遇到廠際(ji)管道（Pipeline between the Plants or District）的(de)設計(ji)，不同(tong)的(de)國內外規范，設計(ji)要求可能不同(tong)。

  在GB 50160《石(shi)油(you)化工(gong)企(qi)業設(she)計防(fang)火規范》中，廠(chang)際管(guan)道指敷(fu)設(she)在石(shi)油(you)化工(gong)企(qi)業、油(you)庫、油(you)氣(qi)碼頭(tou)等(deng)不同圍墻(qiang)界區之間(jian)且通過(guo)公(gong)共(gong)區域、長度(du)小于等(deng)于30km的輸油(you)輸氣(qi)管(guan)道。

  在GB/T 51359《石(shi)(shi)油(you)化(hua)(hua)(hua)工(gong)(gong)廠(chang)(chang)際管(guan)(guan)道(dao)工(gong)(gong)程(cheng)技術(shu)標準》規范中，廠(chang)(chang)際管(guan)(guan)道(dao)指石(shi)(shi)油(you)化(hua)(hua)(hua)工(gong)(gong)及煤化(hua)(hua)(hua)工(gong)(gong)企業(ye)、石(shi)(shi)油(you)庫(ku)、石(shi)(shi)油(you)化(hua)(hua)(hua)工(gong)(gong)碼頭(tou)等(deng)相互間的輸(shu)送(song)可燃氣體、液(ye)化(hua)(hua)(hua)烴(jing)和可燃液(ye)體管(guan)(guan)道(dao)（石(shi)(shi)油(you)化(hua)(hua)(hua)工(gong)(gong)園區除(chu)外）。其特征是敷設在石(shi)(shi)油(you)化(hua)(hua)(hua)工(gong)(gong)及煤化(hua)(hua)(hua)工(gong)(gong)企業(ye)、石(shi)(shi)油(you)庫(ku)、石(shi)(shi)油(you)化(hua)(hua)(hua)工(gong)(gong)碼頭(tou)等(deng)圍(wei)墻或用(yong)地邊(bian)界線之(zhi)間且通過公共區域，長度小于或等(deng)于30km。

  廠(chang)際管(guan)(guan)道(dao)(dao)的(de)特(te)點(dian)是企業圍墻或(huo)用地邊界(jie)線之(zhi)間(jian)(jian)、通(tong)(tong)過公共區(qu)(qu)域(yu)，長(chang)度(du)≤30km。廠(chang)際管(guan)(guan)道(dao)(dao)長(chang)度(du)限定(ding)在(zai)30km，考慮了(le)與(yu)長(chang)距(ju)離輸(shu)(shu)油(you)(you)管(guan)(guan)道(dao)(dao)的(de)兩(liang)切(qie)斷閥間(jian)(jian)距(ju)相協(xie)調。一(yi)(yi)般情況下，長(chang)距(ju)離輸(shu)(shu)送(song)油(you)(you)氣(qi)管(guan)(guan)道(dao)(dao)長(chang)度(du)在(zai)50km以上，有(you)中(zhong)間(jian)(jian)泵站(zhan)(zhan)或(huo)加(jia)壓(ya)站(zhan)(zhan)等特(te)征，而廠(chang)際管(guan)(guan)道(dao)(dao)通(tong)(tong)常是多條管(guan)(guan)道(dao)(dao)并列敷(fu)設，無中(zhong)間(jian)(jian)泵站(zhan)(zhan)或(huo)加(jia)壓(ya)站(zhan)(zhan)，這一(yi)(yi)長(chang)度(du)也(ye)基本涵蓋(gai)了(le)目前石油(you)(you)化工(gong)企業不同圍墻或(huo)用地邊界(jie)之(zhi)間(jian)(jian)的(de)油(you)(you)氣(qi)管(guan)(guan)道(dao)(dao)長(chang)度(du)。廠(chang)際管(guan)(guan)道(dao)(dao)不屬于(yu)地區(qu)(qu)輸(shu)(shu)油(you)(you)（輸(shu)(shu)氣(qi)）管(guan)(guan)道(dao)(dao)，也(ye)不包(bao)括石油(you)(you)化工(gong)園區(qu)(qu)內公用的(de)輸(shu)(shu)送(song)可燃氣(qi)體(ti)、液(ye)化烴和可燃液(ye)體(ti)的(de)管(guan)(guan)道(dao)(dao)。一(yi)(yi)般定(ding)義(yi)廠(chang)際管(guan)(guan)道(dao)(dao)為GC類。
