Ipayipi le-welded elingagqwali libhekisele kwipayipi lensimbi elinokunemba okuqinile kwangaphakathi nangaphandle), ukuqeda okuhle okungaphakathi nangaphandle komhlaba, ukuzungeza, ukuqina, ukuqina kodonga olufanayo. Izinkomba zobuchwepheshe eziphambili zepayipi elingenamikhawulo lensimbi ekhiqizwa yilobu buchwepheshe ziye zafinyelela noma zidlule ngokwedlulele ingxenye yezwe elijwayelekile le-GB12771-2002 ne-ISO4394 / I-1980 (e). Ungakulawula kanjani ukunemba kwepayipi elingenasici
Ngenxa yobuningi obukhulu bendawo enamapayipi wensimbi engagqwali, noma ngabe indawo yangaphandle ayiboniswanga, ngokuvamile ingafinyelela kuma-mesh angama-260. Uma ipayipi le-welded elingenacala ligcwele ngaphakathi nangaphandle, ukuqonda kwalo kuzokwehla. Ngakho-ke, uma kunezidingo ezikhethekile zokuqonda kwepayipi lensimbi, ukucwaswa ngokuvamile akunconywa. Ingaphezulu elibunjiwe lepayipi le-welded yensimbi engenasici selivele likhanya kakhulu. Ipayipi elibandayo elibandayo le-welded i-welded linokusebenza okuhle kakhulu, lingamelana nengcindezi ephezulu, yakhiwa, yakhiwa, yavutha, futhi yathopha ngaphandle kokuqhekeka noma ukugoqa. Kungenza isimo esihlukahlukene esiyinkimbinkimbi kanye nokusebenza kwemishini. Ngemuva kwepayipi le-welded yensimbi engagqwali lingenwa yi-vacuum anveal, ipayipi lensimbi lingacutshungulwa.
Amapayipi wensimbi engagqwali asetshenziselwa ukukhiqiza izakhiwo zemishini, imishini ye-hydraulic, imishini kanye nezinye izinkambu zokukhiqiza. Emasimini okusebenzisa, imishini yezokwelapha, imishini yokunemba, imishini ye-elekthronikhi, amapayipi amanzi adongeni, amapayipi okushisa ancishisiwe kanye namapayipi ashibhile asetshenziswa ukuze anembe okubunjiwe okuphezulu. Amaphayipha amapayipi ajwayelekile awakwazi ukufeza le mfuneko. I-Seko Imishini Ikuthatha Ukuhlaziya ukuthi imishini yokukhiqiza nezinto zokukhiqiza ithinta ukunemba okubucayi kwepayipi elingaphandle elingenamikhawulo yepayipi.
1. Izidingo zokunemba ezinobukhulu bokunemba kwensimbi evuthayo yensimbi engenacala
kusuka ku-GB / T 3639-2000 'Amapayipi wensimbi ahlanganisiwe noma ama-ASTM a1000 ngokunemba kwensimbi engenacala amapayipi ama-welded. Ukuphambuka okuvumelekile kobubanzi (Ithebula 1) kanye nokuphambuka kodonga (Ithebula 2). Ukubekezelelana kwangaphakathi kwepayipi le-welded kuthinteka kakhulu ekubekezelelekeni kobubanzi nobubanzi bodonga. Lo mbhalo awudingi magazini wokubekezelelana kwangaphakathi.
2. Ukuhlaziywa kwezinto ezithinta ukunemba okubucayi kobubanzi bamapayipi wensimbi engagqwali
2.1 Ithonya lobubanzi be-weldip
kanye nokubekezelela
weld
ububanzi bepayipi le- Ngomucu wensimbi, ukunemba okuyisici komqulu we-welding kanye negebe laso.
2) Ithonya lenani le-sizing ngokunemba okuyisisekelo kwepayipi elingaphandle kwe-weldeded auter
inani le-ailing the Pipe eliphakeme eliphakeme kufanele likhulu kakhulu kunaleso sepayipi elijwayelekile le-welded. Umgomo wokuthola inani le-sizing yilena: Inani lokulinganisa elinganele kanye nezikhathi zokuphasa.
2.3 Uhlaka lokuqina komshini wokulinganisa kanye nethonya losayizi wemishini
2.3.1 Uhlaka lokuqina kwe
-elastic deformation yesisekelo somshini wepayipi we-welded we-welded ilingana nesamba sokuguquguquka okuningana kochungechunge lwezingxenye ezicindezelekile ezisekelweni.
2.3.2 usayizi we-rolling force
1) Isilinganiso Sokucindezela Kweyunithi
2) Indawo Yokuxhumana
3) Ukulinganisa amandla okugoqa
2.3.3 Ukuguquguquka kokukhanya kwesisekelo somshini wokulinganisa
2.4 Ithonya Lokukhiqiza Imishini Yemishini Yemishini Yokukhiqiza
Imishini Yokukhiqiza Imishini Yomshini we-Sizing Umshini Ongaphandle Kuthinta Ukubekezelela Ububanzi be-Weldeter
Ukunemba kobukhulu nobubanzi bomcucu wensimbi kuthinta kuphela ukunemba kobubanzi bepayipi elinenkani ngaphambi kokuthambisa, kodwa hhayi okuningi ngesikhathi senqubo yokulinganisa. I-Sizing Passion kanye nenani le-sizing linqunywa ikakhulukazi ngokuya ngokubekezelelana kobubanzi bepayipi elinenkani ngaphambi kokuthambisa. Inani elinele lokudlula kanye nenani le-sizing yisiqinisekiso esiyisisekelo sokwenza ngcono ukunemba kobubanzi bepayipi e-welded. Izici eziphambili ezithinta ukunemba kobubanzi obungaphandle kwepayipi elinenkani zilingana nomshini wokulinganisa kanye nokunemba kokukhiqiza imishini. Hangao tech (seko mishini) Ukunemba okuphezulu ngomshini wepayipi wezimboni eziphezulu ezingenacala Ngemininingwane engaphezulu, sicela uthintane!
