Umehluko nokukhetha phakathi kwepayipi eline-welded nepayipi elingenamthungo

Insimbi engenasici inokusebenza okuhle okuphelele kanye nezimpawu ezinhle zomhlaba ezinhle, futhi zisetshenziswa kabanzi kuzo zonke izindlela zokuphila. Ngokufanayo, amapayipi ensimbi engagqwali awekho okuhlukile. Ipayipi lensimbi engagqwali uhlobo lwensimbi enesigaba esingenalutho, ngokuvamile ihlukaniswe ngepayipi elingagqwali elingenamikhumbi kanye nepayipi elingenalutho. Amapayipi angenamthungo kanye namapayipi we-welded ngamunye anezinzuzo ezinkambeni ezihlukile zohlelo lokusebenza. Lapho ukhetha izinto zokwenziwa kwamapayipi, izidingo zobunjiniyela, izidingo zokusebenza kanye nezindleko zezindleko kudinga ukubhekelwa ukubheka ukuthi uluphi uhlobo lwepayipi lensimbi olufanele kakhulu kwiphrojekthi ethile.

Kukhona nomehluko othile ezindleleni zabo zokucubungula kanye nokusebenza kwazo, umehluko umele kanjena:

1. Inqubo yokukhiqiza yehlukile

Ipayipi elingenamthungo: Ipayipi elingenamthungo lenziwa ngokushisa, likufanekisa futhi ligingqikala kusuka ku-billet, ngakho-ke akukho mali ahlanganisiwe. Le ndlela yokukhiqiza iqinisekisa izindawo ezibushelelezi futhi ezifanayo ngaphakathi nangaphandle kwepayipi, ngaleyo ndlela zinikeze ukugeleza okungcono kokugeleza komoya nokugqwala.

Ipayipi eline-welded: Ipayipi eline-welded lenziwa ngokugoqa ipuleti lensimbi esimweni seshubhu, bese lifaka ipayipi lokwenziwa. Lokhu kusho ukuthi ipayipi eline-welded line-welds eyodwa noma ngaphezulu ekuqondeni ubude. Lawa ma-welds angethula ubuthakathaka kwezinye izinhlelo zokusebenza ezidinga ukuvikelwa okwengeziwe kokugqwala.

2. Izici zokusebenza

Amapayipi angenamthungo: ngoba awekho amalunga anezinwele, amapayipi angenamthungo ngokuvamile anokusebenza okungcono ekushiseni okuphezulu, ingcindezi ephezulu kanye nezindawo ezisolisayo. Zilungele izinhlelo zokusebenza ezidinga amandla aphezulu kanye nokumelana okuphezulu, njengokulethwa kwamafutha kanye nokulethwa kwegesi, ama-boilers amakhemikhali kanye nengcindezelo ephezulu.

Ipayipi le-Welded: Ukusebenza kwepayipi elinenkani kuvame ukuncika kwikhwalithi ye-welding. Ngenkathi zingasetshenziswa kuzicelo eziningi, amalunga we-welded angaba ngumthombo ongaba khona wokugqwala nobuthakathaka. Kodwa-ke, ngezindlela ezifanele zokufafaza nokuvikelwa kokugqwala, ubungozi balezi zinkinga bungancishiswa.

3. Inkambu yesicelo:

Amapayipi angenamthungo: Ngenxa yezimpawu zawo zokusebenza okuphezulu, amapayipi angenamthungo ajwayele ukusetshenziswa kuzinhlelo zokusebenza ezidinga ukuthembeka okuphezulu nokuphepha, okushisa kwamandla okushisa kanye nemishini yamakhemikhali.

Ipayipi le-Welded: Ipayipi eline-welded lilungele ezinye izicelo zobunjiniyela ezijwayelekile nezinhlelo zokusebenza zokucindezela okuphansi, njengezakhiwo zokwakha, ukuhanjiswa kwe-hydraulic kanye nezinhlelo ezijwayelekile zamapayipi. Zivame ukungabizi ngokwengeziwe.
