國內外大(da)(da)中(zhong)型(xing)項目(mu)(mu)(mu)管(guan)道(dao)(dao)器(qi)材選(xuan)用的(de)(de)(de)(de)(de)方法有很多種。有的(de)(de)(de)(de)(de)工(gong)(gong)程(cheng)(cheng)公(gong)司(si)(si)根據以往眾多工(gong)(gong)程(cheng)(cheng)項目(mu)(mu)(mu)的(de)(de)(de)(de)(de)積累總結，把(ba)適(shi)應不同工(gong)(gong)況的(de)(de)(de)(de)(de)各種管(guan)道(dao)(dao)器(qi)材分門別類列(lie)表，匯總為管(guan)道(dao)(dao)器(qi)材選(xuan)用數據庫，在新工(gong)(gong)程(cheng)(cheng)項目(mu)(mu)(mu)設計(ji)時，根據工(gong)(gong)況要求直接(jie)從數據庫中(zhong)拷(kao)貝相(xiang)(xiang)應的(de)(de)(de)(de)(de)管(guan)道(dao)(dao)器(qi)材直接(jie)使用即可。有的(de)(de)(de)(de)(de)工(gong)(gong)程(cheng)(cheng)公(gong)司(si)(si)把(ba)管(guan)道(dao)(dao)器(qi)材選(xuan)用數據庫制作成了計(ji)算機軟件(jian)，輸入設計(ji)工(gong)(gong)況會自動生成相(xiang)(xiang)應體系的(de)(de)(de)(de)(de)管(guan)道(dao)(dao)材料(liao)等級(ji)(ji)表。有的(de)(de)(de)(de)(de)工(gong)(gong)程(cheng)(cheng)公(gong)司(si)(si)在承(cheng)接(jie)的(de)(de)(de)(de)(de)工(gong)(gong)程(cheng)(cheng)項目(mu)(mu)(mu)中(zhong)，在工(gong)(gong)藝專利商提供的(de)(de)(de)(de)(de)工(gong)(gong)藝包內已經包含了詳細(xi)和完整的(de)(de)(de)(de)(de)管(guan)道(dao)(dao)材料(liao)等級(ji)(ji)表；有的(de)(de)(de)(de)(de)大(da)(da)型(xing)石化(hua)、煉化(hua)企業(ye)(ye)集(ji)團（擁有很多家煉化(hua)工(gong)(gong)廠），有統一(yi)的(de)(de)(de)(de)(de)管(guan)道(dao)(dao)材料(liao)等級(ji)(ji)表規定(ding)(ding)，企業(ye)(ye)所屬所有工(gong)(gong)程(cheng)(cheng)項目(mu)(mu)(mu)都遵循此管(guan)道(dao)(dao)材料(liao)等級(ji)(ji)規定(ding)(ding)，如果某(mou)工(gong)(gong)程(cheng)(cheng)公(gong)司(si)(si)承(cheng)接(jie)這家石化(hua)、煉化(hua)企業(ye)(ye)集(ji)團的(de)(de)(de)(de)(de)項目(mu)(mu)(mu)，就不用重新設計(ji)管(guan)道(dao)(dao)材料(liao)等級(ji)(ji)表。

  某國外大型(xing)(xing)煉化(hua)企業(ye)集(ji)團(tuan)，大型(xing)(xing)煉化(hua)企業(ye)集(ji)團(tuan)幾十家煉化(hua)和石化(hua)企業(ye)執行同一個管(guan)(guan)道(dao)材料等(deng)(deng)級表。其(qi)他(ta)工程公司承接某裝置改造項目時，不用(yong)重新設計新的(de)管(guan)(guan)道(dao)材料等(deng)(deng)級表，三維管(guan)(guan)道(dao)設計模型(xing)(xing)的(de)數據庫也是(shi)統一配套做好的(de)。
