國內外大中(zhong)(zhong)型(xing)項(xiang)目(mu)管(guan)(guan)道(dao)(dao)器材(cai)選用的(de)(de)方(fang)法有(you)很多(duo)種。有(you)的(de)(de)工(gong)(gong)(gong)程(cheng)公(gong)(gong)司根據(ju)以往眾(zhong)多(duo)工(gong)(gong)(gong)程(cheng)項(xiang)目(mu)的(de)(de)積累總結，把適應不同工(gong)(gong)(gong)況(kuang)的(de)(de)各種管(guan)(guan)道(dao)(dao)器材(cai)分門別(bie)類列表，匯總為管(guan)(guan)道(dao)(dao)器材(cai)選用數(shu)據(ju)庫(ku)，在新工(gong)(gong)(gong)程(cheng)項(xiang)目(mu)設計(ji)(ji)(ji)時，根據(ju)工(gong)(gong)(gong)況(kuang)要(yao)求直(zhi)接(jie)從數(shu)據(ju)庫(ku)中(zhong)(zhong)拷貝(bei)相應的(de)(de)管(guan)(guan)道(dao)(dao)器材(cai)直(zhi)接(jie)使用即可。有(you)的(de)(de)工(gong)(gong)(gong)程(cheng)公(gong)(gong)司把管(guan)(guan)道(dao)(dao)器材(cai)選用數(shu)據(ju)庫(ku)制(zhi)作成了(le)計(ji)(ji)(ji)算(suan)機軟(ruan)件，輸入設計(ji)(ji)(ji)工(gong)(gong)(gong)況(kuang)會自動生成相應體系(xi)的(de)(de)管(guan)(guan)道(dao)(dao)材(cai)料(liao)等(deng)級(ji)表。有(you)的(de)(de)工(gong)(gong)(gong)程(cheng)公(gong)(gong)司在承(cheng)接(jie)的(de)(de)工(gong)(gong)(gong)程(cheng)項(xiang)目(mu)中(zhong)(zhong)，在工(gong)(gong)(gong)藝專利商提供的(de)(de)工(gong)(gong)(gong)藝包(bao)(bao)內已經(jing)包(bao)(bao)含了(le)詳細和完整的(de)(de)管(guan)(guan)道(dao)(dao)材(cai)料(liao)等(deng)級(ji)表；有(you)的(de)(de)大型(xing)石化(hua)、煉化(hua)企(qi)(qi)業(ye)集團(tuan)（擁(yong)有(you)很多(duo)家煉化(hua)工(gong)(gong)(gong)廠），有(you)統一的(de)(de)管(guan)(guan)道(dao)(dao)材(cai)料(liao)等(deng)級(ji)表規定，企(qi)(qi)業(ye)所屬(shu)所有(you)工(gong)(gong)(gong)程(cheng)項(xiang)目(mu)都(dou)遵循此管(guan)(guan)道(dao)(dao)材(cai)料(liao)等(deng)級(ji)規定，如果某(mou)工(gong)(gong)(gong)程(cheng)公(gong)(gong)司承(cheng)接(jie)這家石化(hua)、煉化(hua)企(qi)(qi)業(ye)集團(tuan)的(de)(de)項(xiang)目(mu)，就不用重新設計(ji)(ji)(ji)管(guan)(guan)道(dao)(dao)材(cai)料(liao)等(deng)級(ji)表。

  某國外(wai)大型(xing)煉化企業(ye)(ye)集團，大型(xing)煉化企業(ye)(ye)集團幾十家煉化和石化企業(ye)(ye)執行同一(yi)個管道材(cai)料等(deng)級表。其他工(gong)程公(gong)司(si)承接(jie)某裝置改(gai)造項目時，不用重新設計新的管道材(cai)料等(deng)級表，三維(wei)管道設計模型(xing)的數據庫也是統一(yi)配(pei)套做好的。
