在工程設計中，常遇到廠際管(guan)道（Pipeline between the Plants or District）的(de)設計，不(bu)同(tong)的(de)國內外規范，設計要(yao)求(qiu)可能(neng)不(bu)同(tong)。

  在(zai)GB 50160《石油(you)化(hua)工(gong)企(qi)業(ye)設計防火(huo)規范》中，廠際管道指(zhi)敷設在(zai)石油(you)化(hua)工(gong)企(qi)業(ye)、油(you)庫、油(you)氣(qi)碼頭(tou)等不(bu)同(tong)圍墻界(jie)區(qu)之間且通過(guo)公共區(qu)域(yu)、長度小(xiao)于等于30km的輸油(you)輸氣(qi)管道。

  在GB/T 51359《石(shi)(shi)油化(hua)(hua)工(gong)廠(chang)際管道(dao)工(gong)程技術標(biao)準》規(gui)范中，廠(chang)際管道(dao)指石(shi)(shi)油化(hua)(hua)工(gong)及(ji)煤(mei)化(hua)(hua)工(gong)企業、石(shi)(shi)油庫、石(shi)(shi)油化(hua)(hua)工(gong)碼頭等(deng)相互(hu)間的輸(shu)送可燃(ran)(ran)氣體、液化(hua)(hua)烴(jing)和(he)可燃(ran)(ran)液體管道(dao)（石(shi)(shi)油化(hua)(hua)工(gong)園區(qu)除外）。其特征是(shi)敷設在石(shi)(shi)油化(hua)(hua)工(gong)及(ji)煤(mei)化(hua)(hua)工(gong)企業、石(shi)(shi)油庫、石(shi)(shi)油化(hua)(hua)工(gong)碼頭等(deng)圍墻(qiang)或用地邊界線之間且通過公共區(qu)域，長(chang)度小于(yu)或等(deng)于(yu)30km。

  廠際管(guan)(guan)(guan)(guan)道(dao)(dao)(dao)(dao)的特點是企(qi)業(ye)圍墻或(huo)用(yong)地(di)邊(bian)界(jie)線之(zhi)間、通過公共區域，長度(du)(du)≤30km。廠際管(guan)(guan)(guan)(guan)道(dao)(dao)(dao)(dao)長度(du)(du)限定在(zai)(zai)30km，考慮了(le)與長距(ju)離輸油(you)管(guan)(guan)(guan)(guan)道(dao)(dao)(dao)(dao)的兩切斷閥間距(ju)相協調。一般情況(kuang)下，長距(ju)離輸送油(you)氣(qi)管(guan)(guan)(guan)(guan)道(dao)(dao)(dao)(dao)長度(du)(du)在(zai)(zai)50km以上，有中(zhong)間泵(beng)站(zhan)或(huo)加(jia)壓(ya)站(zhan)等(deng)特征，而(er)廠際管(guan)(guan)(guan)(guan)道(dao)(dao)(dao)(dao)通常是多條管(guan)(guan)(guan)(guan)道(dao)(dao)(dao)(dao)并列敷設，無中(zhong)間泵(beng)站(zhan)或(huo)加(jia)壓(ya)站(zhan)，這一長度(du)(du)也基本涵蓋了(le)目前石油(you)化(hua)工(gong)企(qi)業(ye)不(bu)同圍墻或(huo)用(yong)地(di)邊(bian)界(jie)之(zhi)間的油(you)氣(qi)管(guan)(guan)(guan)(guan)道(dao)(dao)(dao)(dao)長度(du)(du)。廠際管(guan)(guan)(guan)(guan)道(dao)(dao)(dao)(dao)不(bu)屬于地(di)區輸油(you)（輸氣(qi)）管(guan)(guan)(guan)(guan)道(dao)(dao)(dao)(dao)，也不(bu)包括石油(you)化(hua)工(gong)園區內(nei)公用(yong)的輸送可燃氣(qi)體、液化(hua)烴和可燃液體的管(guan)(guan)(guan)(guan)道(dao)(dao)(dao)(dao)。一般定義廠際管(guan)(guan)(guan)(guan)道(dao)(dao)(dao)(dao)為GC類。
