在工程設(she)計中，常(chang)遇到廠際管道（Pipeline between the Plants or District）的(de)設(she)計，不同的(de)國內外規范，設(she)計要求可能不同。

  在GB 50160《石油(you)化(hua)工(gong)企業設計防火規范》中，廠際管道指敷(fu)設在石油(you)化(hua)工(gong)企業、油(you)庫、油(you)氣碼頭等不同(tong)圍墻界區之間且(qie)通過(guo)公(gong)共區域、長度小于等于30km的輸油(you)輸氣管道。

  在GB/T 51359《石(shi)油(you)(you)(you)(you)(you)(you)化工(gong)(gong)廠(chang)際管道工(gong)(gong)程技(ji)術(shu)標(biao)準》規范中(zhong)，廠(chang)際管道指石(shi)油(you)(you)(you)(you)(you)(you)化工(gong)(gong)及煤化工(gong)(gong)企業(ye)(ye)、石(shi)油(you)(you)(you)(you)(you)(you)庫(ku)、石(shi)油(you)(you)(you)(you)(you)(you)化工(gong)(gong)碼頭(tou)等相互間(jian)的輸送(song)可燃氣體(ti)、液(ye)化烴(jing)和可燃液(ye)體(ti)管道（石(shi)油(you)(you)(you)(you)(you)(you)化工(gong)(gong)園(yuan)區(qu)除外(wai)）。其(qi)特征是敷設在石(shi)油(you)(you)(you)(you)(you)(you)化工(gong)(gong)及煤化工(gong)(gong)企業(ye)(ye)、石(shi)油(you)(you)(you)(you)(you)(you)庫(ku)、石(shi)油(you)(you)(you)(you)(you)(you)化工(gong)(gong)碼頭(tou)等圍墻或(huo)用地邊界線之間(jian)且通過公(gong)共(gong)區(qu)域，長(chang)度小于(yu)或(huo)等于(yu)30km。

  廠(chang)際(ji)(ji)管(guan)(guan)(guan)(guan)道(dao)(dao)(dao)的(de)(de)特(te)點是(shi)企業圍墻或(huo)(huo)用地邊界線之間(jian)、通(tong)過公共(gong)區域，長(chang)度(du)(du)≤30km。廠(chang)際(ji)(ji)管(guan)(guan)(guan)(guan)道(dao)(dao)(dao)長(chang)度(du)(du)限(xian)定在30km，考慮了與長(chang)距(ju)(ju)離輸油(you)(you)管(guan)(guan)(guan)(guan)道(dao)(dao)(dao)的(de)(de)兩切(qie)斷閥間(jian)距(ju)(ju)相(xiang)協(xie)調。一(yi)般情況下，長(chang)距(ju)(ju)離輸送油(you)(you)氣(qi)管(guan)(guan)(guan)(guan)道(dao)(dao)(dao)長(chang)度(du)(du)在50km以上，有中(zhong)間(jian)泵站(zhan)或(huo)(huo)加壓(ya)站(zhan)等特(te)征，而廠(chang)際(ji)(ji)管(guan)(guan)(guan)(guan)道(dao)(dao)(dao)通(tong)常是(shi)多條管(guan)(guan)(guan)(guan)道(dao)(dao)(dao)并列敷設，無中(zhong)間(jian)泵站(zhan)或(huo)(huo)加壓(ya)站(zhan)，這一(yi)長(chang)度(du)(du)也(ye)基本涵蓋(gai)了目(mu)前石(shi)油(you)(you)化工(gong)(gong)企業不(bu)同圍墻或(huo)(huo)用地邊界之間(jian)的(de)(de)油(you)(you)氣(qi)管(guan)(guan)(guan)(guan)道(dao)(dao)(dao)長(chang)度(du)(du)。廠(chang)際(ji)(ji)管(guan)(guan)(guan)(guan)道(dao)(dao)(dao)不(bu)屬于地區輸油(you)(you)（輸氣(qi)）管(guan)(guan)(guan)(guan)道(dao)(dao)(dao)，也(ye)不(bu)包(bao)括(kuo)石(shi)油(you)(you)化工(gong)(gong)園區內公用的(de)(de)輸送可(ke)燃氣(qi)體、液化烴(jing)和可(ke)燃液體的(de)(de)管(guan)(guan)(guan)(guan)道(dao)(dao)(dao)。一(yi)般定義(yi)廠(chang)際(ji)(ji)管(guan)(guan)(guan)(guan)道(dao)(dao)(dao)為GC類。
