在(zai)工程設計中(zhong)，常遇(yu)到廠際管道（Pipeline between the Plants or District）的(de)設計，不(bu)同的(de)國內外規范，設計要求可能不(bu)同。

  在GB 50160《石(shi)油(you)化(hua)工企業設(she)計(ji)防火規范》中，廠際(ji)管(guan)道指(zhi)敷(fu)設(she)在石(shi)油(you)化(hua)工企業、油(you)庫、油(you)氣碼頭等(deng)(deng)不同圍墻(qiang)界區之(zhi)間且通(tong)過公共(gong)區域、長度小于等(deng)(deng)于30km的輸油(you)輸氣管(guan)道。

  在GB/T 51359《石(shi)(shi)油(you)(you)化(hua)(hua)工(gong)廠際管道工(gong)程技(ji)術標準》規范中，廠際管道指石(shi)(shi)油(you)(you)化(hua)(hua)工(gong)及煤(mei)化(hua)(hua)工(gong)企業、石(shi)(shi)油(you)(you)庫、石(shi)(shi)油(you)(you)化(hua)(hua)工(gong)碼頭(tou)等(deng)(deng)相互間的輸(shu)送可燃氣體(ti)、液(ye)化(hua)(hua)烴(jing)和可燃液(ye)體(ti)管道（石(shi)(shi)油(you)(you)化(hua)(hua)工(gong)園(yuan)區除(chu)外）。其特征(zheng)是敷(fu)設在石(shi)(shi)油(you)(you)化(hua)(hua)工(gong)及煤(mei)化(hua)(hua)工(gong)企業、石(shi)(shi)油(you)(you)庫、石(shi)(shi)油(you)(you)化(hua)(hua)工(gong)碼頭(tou)等(deng)(deng)圍(wei)墻或用地邊界線(xian)之(zhi)間且通過公共區域，長度小于或等(deng)(deng)于30km。

  廠際(ji)(ji)管(guan)道(dao)(dao)(dao)的(de)(de)特(te)點是企(qi)(qi)業(ye)圍墻或用(yong)地邊(bian)界線之(zhi)間(jian)(jian)、通(tong)過公共區(qu)域，長(chang)度(du)(du)≤30km。廠際(ji)(ji)管(guan)道(dao)(dao)(dao)長(chang)度(du)(du)限定(ding)在30km，考慮了與長(chang)距離輸油管(guan)道(dao)(dao)(dao)的(de)(de)兩切(qie)斷閥間(jian)(jian)距相協調。一般(ban)(ban)情(qing)況下，長(chang)距離輸送(song)油氣管(guan)道(dao)(dao)(dao)長(chang)度(du)(du)在50km以上(shang)，有中(zhong)間(jian)(jian)泵站或加壓站等(deng)特(te)征，而(er)廠際(ji)(ji)管(guan)道(dao)(dao)(dao)通(tong)常是多條(tiao)管(guan)道(dao)(dao)(dao)并列敷設，無(wu)中(zhong)間(jian)(jian)泵站或加壓站，這一長(chang)度(du)(du)也基本涵蓋了目前石(shi)油化(hua)(hua)工(gong)企(qi)(qi)業(ye)不(bu)同圍墻或用(yong)地邊(bian)界之(zhi)間(jian)(jian)的(de)(de)油氣管(guan)道(dao)(dao)(dao)長(chang)度(du)(du)。廠際(ji)(ji)管(guan)道(dao)(dao)(dao)不(bu)屬于地區(qu)輸油（輸氣）管(guan)道(dao)(dao)(dao)，也不(bu)包括石(shi)油化(hua)(hua)工(gong)園(yuan)區(qu)內公用(yong)的(de)(de)輸送(song)可燃氣體、液化(hua)(hua)烴和可燃液體的(de)(de)管(guan)道(dao)(dao)(dao)。一般(ban)(ban)定(ding)義廠際(ji)(ji)管(guan)道(dao)(dao)(dao)為GC類。
