在(zai)工程設(she)計中，常遇到廠際管(guan)道（Pipeline between the Plants or District）的設(she)計，不同的國(guo)內外(wai)規范，設(she)計要求可(ke)能不同。

  在GB 50160《石油化工(gong)企業設(she)計防(fang)火規范》中(zhong)，廠際管道(dao)指(zhi)敷設(she)在石油化工(gong)企業、油庫、油氣碼頭等不(bu)同(tong)圍墻(qiang)界區之間且通過(guo)公共區域、長度小于(yu)等于(yu)30km的輸油輸氣管道(dao)。

  在GB/T 51359《石(shi)油(you)(you)化(hua)(hua)工(gong)(gong)廠際(ji)管道工(gong)(gong)程技術(shu)標(biao)準》規范中，廠際(ji)管道指(zhi)石(shi)油(you)(you)化(hua)(hua)工(gong)(gong)及(ji)煤化(hua)(hua)工(gong)(gong)企業、石(shi)油(you)(you)庫、石(shi)油(you)(you)化(hua)(hua)工(gong)(gong)碼頭(tou)等(deng)相互間的輸送可燃氣體(ti)、液化(hua)(hua)烴和可燃液體(ti)管道（石(shi)油(you)(you)化(hua)(hua)工(gong)(gong)園區除外）。其特征是敷設(she)在石(shi)油(you)(you)化(hua)(hua)工(gong)(gong)及(ji)煤化(hua)(hua)工(gong)(gong)企業、石(shi)油(you)(you)庫、石(shi)油(you)(you)化(hua)(hua)工(gong)(gong)碼頭(tou)等(deng)圍墻或用地邊界(jie)線之間且通過公共(gong)區域，長度小于或等(deng)于30km。

  廠(chang)(chang)際管(guan)(guan)道(dao)(dao)的(de)特點是企業圍(wei)(wei)墻或(huo)(huo)(huo)(huo)用(yong)地邊界線之間(jian)、通過公共(gong)區(qu)域，長(chang)(chang)(chang)(chang)度≤30km。廠(chang)(chang)際管(guan)(guan)道(dao)(dao)長(chang)(chang)(chang)(chang)度限定(ding)在(zai)30km，考慮(lv)了與長(chang)(chang)(chang)(chang)距(ju)離輸油(you)(you)(you)管(guan)(guan)道(dao)(dao)的(de)兩切斷閥間(jian)距(ju)相協(xie)調(diao)。一(yi)(yi)般情況下，長(chang)(chang)(chang)(chang)距(ju)離輸送油(you)(you)(you)氣(qi)管(guan)(guan)道(dao)(dao)長(chang)(chang)(chang)(chang)度在(zai)50km以上，有中間(jian)泵站(zhan)(zhan)(zhan)或(huo)(huo)(huo)(huo)加壓站(zhan)(zhan)(zhan)等特征，而(er)廠(chang)(chang)際管(guan)(guan)道(dao)(dao)通常是多(duo)條(tiao)管(guan)(guan)道(dao)(dao)并列(lie)敷(fu)設，無中間(jian)泵站(zhan)(zhan)(zhan)或(huo)(huo)(huo)(huo)加壓站(zhan)(zhan)(zhan)，這一(yi)(yi)長(chang)(chang)(chang)(chang)度也基本涵蓋了目前石(shi)(shi)油(you)(you)(you)化(hua)(hua)工(gong)企業不(bu)同(tong)圍(wei)(wei)墻或(huo)(huo)(huo)(huo)用(yong)地邊界之間(jian)的(de)油(you)(you)(you)氣(qi)管(guan)(guan)道(dao)(dao)長(chang)(chang)(chang)(chang)度。廠(chang)(chang)際管(guan)(guan)道(dao)(dao)不(bu)屬于地區(qu)輸油(you)(you)(you)（輸氣(qi)）管(guan)(guan)道(dao)(dao)，也不(bu)包括(kuo)石(shi)(shi)油(you)(you)(you)化(hua)(hua)工(gong)園區(qu)內公用(yong)的(de)輸送可(ke)燃氣(qi)體、液化(hua)(hua)烴和可(ke)燃液體的(de)管(guan)(guan)道(dao)(dao)。一(yi)(yi)般定(ding)義廠(chang)(chang)際管(guan)(guan)道(dao)(dao)為(wei)GC類。
