   提高生產效率：通(tong)過在工廠中集中完成大(da)部分工作，可以(yi)節省現場施(shi)工的時間和資源。

   降低質量風險(xian)：在工(gong)廠環境中進(jin)行的精(jing)細加工(gong)和(he)質量控制可以減(jian)少現場安裝時的質量問題。

   加速(su)工(gong)程(cheng)進度：預制過程(cheng)減(jian)少了(le)現場安裝的(de)工(gong)作量，從而加快了(le)整個工(gong)程(cheng)的(de)建設速(su)度。

   減少現場(chang)安(an)裝量：通過預先(xian)完成的預制工作，可(ke)以在現場(chang)更(geng)高效(xiao)地(di)進(jin)行(xing)管道系(xi)統的安(an)裝，進(jin)一步提升工作效(xiao)率(lv)。

   管道(dao)預制通(tong)常是在(zai)特(te)定(ding)的(de)區(qu)域（如預制場(chang)）內進行，這個(ge)區(qu)域配(pei)備有機械化(hua)設(she)備、生(sheng)產線和自動化(hua)技術，以(yi)便對(dui)管道(dao)零(ling)部件進行批量(liang)生(sheng)產和加(jia)工。這種(zhong)方式采用(yong)了“先(xian)工廠(chang)后(hou)現場(chang)”的(de)建(jian)設(she)模式，通(tong)過對(dui)管道(dao)零(ling)部件的(de)提(ti)前制造和加(jia)工，使得管道(dao)構件的(de)制造周期(qi)縮短，終降低(di)了工程建(jian)設(she)成本并提(ti)高(gao)了生(sheng)產效(xiao)率和質量(liang),工廠(chang)化(hua)管道(dao)焊接預制
