工(gong)藝(yi)(yi)(yi)和(he)管(guan)道(dao)互相融合(he)，在設計(ji)(ji)時密不(bu)可分。國內外有(you)些(xie)設計(ji)(ji)單位工(gong)藝(yi)(yi)(yi)和(he)管(guan)道(dao)仍是(shi)同(tong)一個專業，稱(cheng)作(zuo)“工(gong)藝(yi)(yi)(yi)管(guan)道(dao)”專業，有(you)些(xie)設計(ji)(ji)單位分為工(gong)藝(yi)(yi)(yi)專業和(he)管(guan)道(dao)專業。無論如何分工(gong)，作(zuo)為壓力管(guan)道(dao)專業，應首(shou)先(xian)理解透徹(che)工(gong)藝(yi)(yi)(yi)專業圖紙文(wen)件，明白工(gong)藝(yi)(yi)(yi)原理，才(cai)能保證(zheng)壓力管(guan)道(dao)專業設計(ji)(ji)質(zhi)量和(he)工(gong)作(zuo)效(xiao)率。

  石(shi)油(you)化(hua)(hua)工(gong)(gong)工(gong)(gong)程(cheng)建(jian)(jian)設項目具(ju)有(you)一定的周期(qi)性，有(you)些(xie)(xie)年(nian)份(fen)煉油(you)裝(zhuang)置(zhi)建(jian)(jian)設工(gong)(gong)程(cheng)較多，有(you)些(xie)(xie)年(nian)份(fen)煤制油(you)煤化(hua)(hua)工(gong)(gong)裝(zhuang)置(zhi)建(jian)(jian)設工(gong)(gong)程(cheng)較多，有(you)些(xie)(xie)年(nian)份(fen)化(hua)(hua)工(gong)(gong)裝(zhuang)置(zhi)建(jian)(jian)設工(gong)(gong)程(cheng)較多，有(you)些(xie)(xie)年(nian)份(fen)電(dian)力輕工(gong)(gong)等裝(zhuang)置(zhi)建(jian)(jian)設工(gong)(gong)程(cheng)較多，在這(zhe)種(zhong)市(shi)場經濟主導的大環境下(xia)，設計單位能中標(biao)的裝(zhuang)置(zhi)類(lei)型也在變化(hua)(hua)。需要壓力管道(dao)設計人員熟練設計煉油(you)（常減壓、催化(hua)(hua)重(zhong)整(zheng)、加氫等）、化(hua)(hua)工(gong)(gong)（乙烯(xi)、化(hua)(hua)肥、LNG、LPG、PP、苯乙烯(xi)等）、煤制油(you)等各種(zhong)裝(zhuang)置(zhi)。

  實踐證明，無論是(shi)(shi)化工(gong)裝置(zhi)(zhi)、煉油裝置(zhi)(zhi)，還(huan)是(shi)(shi)制藥裝置(zhi)(zhi)的(de)(de)壓力(li)管(guan)(guan)(guan)道設(she)(she)計(ji)(ji)(ji)，僅是(shi)(shi)工(gong)藝專業設(she)(she)計(ji)(ji)(ji)內容(rong)不(bu)同(tong)(tong)，對于壓力(li)管(guan)(guan)(guan)道專業設(she)(she)計(ji)(ji)(ji)人員，設(she)(she)計(ji)(ji)(ji)原(yuan)理(li)和(he)內容(rong)是(shi)(shi)相同(tong)(tong)的(de)(de)，壓力(li)管(guan)(guan)(guan)道設(she)(she)計(ji)(ji)(ji)人員掌握了管(guan)(guan)(guan)廊、塔(ta)、容(rong)器(qi)、反(fan)應(ying)器(qi)、換熱(re)設(she)(she)備、加熱(re)爐、泵、壓縮機、罐等設(she)(she)備、設(she)(she)施及其有關管(guan)(guan)(guan)道的(de)(de)配管(guan)(guan)(guan)設(she)(she)計(ji)(ji)(ji)原(yuan)理(li)和(he)好(hao)的(de)(de)設(she)(she)計(ji)(ji)(ji)做(zuo)法，就(jiu)可(ke)以較好(hao)地完成這些不(bu)同(tong)(tong)類型(xing)裝置(zhi)(zhi)的(de)(de)設(she)(she)備設(she)(she)施的(de)(de)壓力(li)管(guan)(guan)(guan)道設(she)(she)計(ji)(ji)(ji)。本章節(jie)簡要(yao)講(jiang)述一些裝置(zhi)(zhi)的(de)(de)工(gong)藝及布置(zhi)(zhi)。
