Iziphambano zingahlukaniswa zibe ububanzi obulinganayo kanye nobubanzi obuncishisiwe, futhi i-nozzle iphetha ngobubanzi obulinganayoiziphambanozinosayizi ofanayo; Usayizi wepayipi oyinhloko weukunciphisa isiphambanokuyefana, kuyilapho ubukhulu bepayipi legatsha buncane kunosayizi wepayipi oyinhloko. Isiphambano sensimbi engagqwali uhlobo lokufakwa kwamapayipi okusetshenziswa egatsheni lepayipi. Ukuze kwenziwe isiphambano ngamapayipi angenamthungo, okwamanje kunezinqubo ezimbili ezivame ukusetshenziswa: ukuqhuma kwe-hydraulic nokucindezela okushisayo.
A. I-hydraulic bulging of hydraulic bulging cross kuyinqubo yokwakha yokukhulisa ipayipi legatsha ngokusebenzisa isinxephezelo se-axial sensimbi. Inqubo iwukusebenzisa umshini wokunyathelisa okhethekile we-hydraulic ukuze ujove uketshezi epayipini elingenalutho elinobubanzi obufana nesiphambano, futhi ukhiphe ipayipi lingenalutho ngokunyakaza okuphakathi nendawo kwamasilinda amabili avundlile omshini wokunyathelisa we-hydraulic. Umthamo wepayipi elingenalutho uba mncane ngemva kokucindezelwa, futhi ingcindezi yoketshezi epayipini elingenalutho liyakhula ngevolumu yepayipi elingenalutho liba lincane. Lapho ingcindezi edingekayo yokwandiswa kwepayipi legatsha eliphambanayo ifinyelelwa, Ngaphansi kwesenzo esiphindwe kabili sokucindezela kwe-liquid kusilinda eseceleni kanye ne-tube engenalutho, izinto zensimbi zigeleza eduze komgodi wangaphakathi wesikhunta futhi zinwebeka ngaphandle kwepayipi legatsha. Inqubo ye-hydraulic bulging yesiphambano ingakhiwa ngesikhathi esisodwa, ngokusebenza kahle kokukhiqiza okuphezulu; Ukuqina kodonga lwepayipi elikhulu kanye nehlombe lesiphambano kwanda. Ngenxa yomthamo omkhulu wemishini edingekayo ukuze kuqhutshekwe ne-hydraulic bulging yesiphambano esingenamthungo, okwamanje, isetshenziswa kakhulu ekwenzeni isiphambano sodonga olujwayelekile esingaphansi kwe-DN400 e-China. Izinto zokwakha ezisebenzayo insimbi ye-carbon steel, i-alloy iron ephansi nensimbi engagqwali enomkhuba wokuqina obandayo ophansi, okuhlanganisa nezinye izinto zensimbi ezingenayo ayoni, njengethusi, i-aluminium, i-titanium, njll.
B. Ukucindezela okushisayo ukwenza isiphambano ukwenza isiphambano sibe sicaba ipayipi lingenalutho libe likhudlwana kunobubanzi beisiphambanomayelana nobubanzi besiphambano, futhi uvule imbobo engxenyeni lapho ipayipi legatsha leluliwe; Ishubhu elingenalutho liyashiswa bese lifakwa endaweni yokufa, bese ifa lokudonsa ipayipi legatsha lifakwa epayipini elingenalutho; Ngaphansi kwesenzo sokucindezela, ithubhu elingenalutho licindezelwa nge-radially. Phakathi nenqubo yokucindezelwa kwe-radial, insimbi igeleza ibheke epayipini legatsha bese yenza ipayipi legatsha ngaphansi komdwebo we-die. Yonke inqubo yenziwa ngokucindezelwa kwe-radial kwe-tube engenalutho kanye nenqubo yokwelula yepayipi yegatsha. Ngokungafani ne-hydraulic bulging spool, insimbi ye-spool ecindezelwe ngokushisayo inxeshezelwa ngokunyakaza kwe-radial yepayipi elingenalutho, ngakho-ke kubizwa nangokuthi inqubo yesinxephezelo se-radial. I-tonnage yemishini edingekayo yokwakha impahla iyancipha ngenxa yokushisa nokucindezela kwesiphambano.Isiphambano esicindezelwe ngokushisayoinokuvumelana nezimo ezibanzi ezintweni, futhi iyasebenza ezintweni zensimbi ephansi ye-carbon, i-alloy steel nensimbi engagqwali; Ikakhulukazi esiphambanweni esinobubanzi obukhulu nodonga lwamapayipi aminyene, le nqubo yokwakha ngokuvamile iyamukelwa.
