1.Ipayipi lensimbi elingenamthungo: ipayipi elingenamthungo liwuhlobo lwensimbi ende enengxenye engenalutho futhi ayinamthungo nxazonke.Ipayipi lensimbi linendawo engenalutho, esetshenziswa kakhulu ukuthutha uketshezi, njengowoyela, igesi yemvelo, igesi, amanzi nezinye izinto eziqinile.Uma kuqhathaniswa nensimbi eqinile njengensimbi eyindilinga, ipayipi elingenamthungo linamandla afanayo okugoba kanye ne-torsion kanye nesisindo esilula.Isetshenziswa kakhulu ekwenzeni izingxenye zesakhiwo kanye nezingxenye zemishini, njengepayipi lokubhoboza i-petroleum, i-automobile transmission shaft, uhlaka lwamabhayisikili kanye nesikafula sensimbi esisetshenziswa ekwakheni.Ingakwazi ukuthuthukisa izinga lokusetshenziswa kwempahla, yenza inqubo yokukhiqiza ibe lula, yonge izinto kanye nesikhathi sokucubungula ngokusebenzisa ipayipi elingenamthungo ukwenza izingxenye zendandatho, njengeringi eliginqikayo, umkhono kajack, njll. izikhali.Umgqomo nomgqomo zenziwe nge-steel tube.Ngokusho kokuma kwendawo ye-cross-sectional, amapayipi ensimbi angahlukaniswa abe yipayipi eliyindilinga kanye nepayipi elimise okukhethekile.Ngenxa yokuthi indawo yendilinga inkulu kakhulu ngaphansi kwesimo se-perimeter elinganayo, uketshezi oluningi lungathuthwa ngeshubhu eliyindilinga.Ukwengeza, lapho isigaba sendandatho sithwala ukucindezela kwe-radial yangaphakathi noma yangaphandle, amandla afana kakhulu.Ngakho-ke, amashubhu amaningi angenamthungo amashubhu ayindilinga, ahlukaniswe abe ukugoqa okushisayo nokugoqa okubandayo.Izinto ezivamile: 20 #, 45 #, Q345, 20g, 20Cr, 35CrMo, 40Cr, 42CrMo, 12CrMo, 12Cr1MoVG, 15CrMoG, njll;Uchungechunge lwensimbi engagqwali luhlobo lwensimbi eyindilinga ende engenalutho, esetshenziswa kabanzi ku-petroleum, amakhemikhali, ezokwelapha, ekudleni, embonini ekhanyayo, amathuluzi emishini kanye namanye amapayipi ezimboni kanye nezingxenye zesakhiwo semishini.Ngaphezu kwalokho, lapho amandla okugoba kanye ne-torsion efanayo, isisindo silula, ngakho-ke sisetshenziswa kabanzi ekukhiqizeni izingxenye zemishini kanye nezakhiwo zobunjiniyela.Futhi evame ukusetshenziselwa ifenisha, i-kitchenware, njll, izinto ezivamile: 201, 304, 316, 316L, 310, 310S, njll.
2. Ipuleti lensimbi: iyinsimbi eyisicaba enensimbi encibilikisiwe futhi icindezelwe ngemva kokupholisa.Iyisicaba futhi ingunxande, futhi ingagoqwa ngokuqondile noma isikwe emgqeni wensimbi obanzi.Ipuleti lensimbi lihlukaniswe libe ukugoqa okushisayo kanye nokugoqa okubandayo ngokuya ngokugoqeka.Ngokusho kokuqina kwepuleti lensimbi, ipuleti lensimbi elincanyana< 4 mm (okuyi-thinnest 0.2 mm), ipuleti lensimbi eliwugqinsi omaphakathi 4 ~ 60 mm, ipuleti lensimbi eliwugqinsi 60 ~ 115 mm.Ububanzi beshidi buyi-500-1500 mm;Ububanzi bepuleti eliwugqinsi buyi-600-3000 mm.Ngokwezinhlobo zensimbi, kunensimbi evamile, insimbi yekhwalithi ephezulu, i-alloy steel, i-spring steel, insimbi engagqwali, insimbi yamathuluzi, insimbi engangeni ekushiseni, insimbi enensimbi, insimbi ye-silicon neshidi lensimbi ehlanzekile yezimboni;Ngokusho kokusetshenziswa kochwepheshe, kukhona ipuleti yomphongolo kawoyela, ipuleti le-enamel, ipuleti elingangenwa izinhlamvu, njll;Ngokusho koqweqwe olungaphezulu, kukhona ishidi elinothayela, i-tinplate, ipuleti lomthofu, ipuleti lensimbi eliyinhlanganisela yepulasitiki, njll. Izinto ezijwayelekile: Q235, 16Mn (q355b), 20 #, 45 #, 65Mn, 40Cr, 42CrMo, 304, 201, 316 , njll.
3. Ipayipi elishiselwe: ipayipi lensimbi elishiselwe, elaziwa nangokuthi ipayipi elishiselwe, ipayipi lensimbi elenziwe ngepuleti lensimbi noma i-strip ngemva kokugoqa nokubunjwa, ubude obujwayelekile obungamamitha ayi-6.Inqubo yokukhiqiza ipayipi yensimbi ehlanganisiwe ilula, ukusebenza kahle kokukhiqiza kuphezulu, izinhlobonhlobo kanye nokucaciswa kuningi, ukutshalwa kwezimali kwemishini kuncane, kodwa amandla ajwayelekile aphansi kunepayipi lensimbi engenamthungo.Welded steel pipe ihlukaniswe iqonde ipayipi ashiselwe futhi Kuvunguza ashiselwe ipayipi ngokusho uhlobo weld.Ukuhlukaniswa ngendlela yokukhiqiza: ukuhlukaniswa kwenqubo - ipayipi elishiselwe i-arc, ipayipi elishiselwe ukumelana, (imvamisa ephezulu, imvamisa ephansi) ipayipi elishiselwe igesi, ipayipi elishiselwe esithandweni.Ukushisela komthungo oqondile kusetshenziselwa ipayipi elishiselwe ububanzi elincane, kanti ukushisela okuvunguza kusetshenziselwa ipayipi elikhulu elishiselwe ububanzi;Ngokusho kokuma kokuphela kwepayipi lensimbi, lingahlukaniswa libe yipayipi elihlanganisiwe eliyisiyingi futhi elimise okukhethekile (isikwele, unxande, njll.) ipayipi elihlanganisiwe;Ngokusho kwezinto ezihlukahlukene kanye nokusetshenziswa, ingahlukaniswa ibe uketshezi lwami oludlulisa ipayipi lensimbi elishiselwe, uketshezi oluphansi lwengcindezi oludlulisa ipayipi lensimbi eliphehliwe, ipayipi lensimbi elihambisa ibhande, njll. Inqubo yokukhiqiza ipayipi ehlanganisiwe ilula, ukusebenza kahle kokukhiqiza okuphezulu, izindleko eziphansi, ukuthuthukiswa okusheshayo.Amandla epayipi elishiselwe okuvunguza ngokuvamile aphakeme kunalawo wepayipi elishiselwe ngokuqondile.Ingasetshenziselwa ukukhiqiza ipayipi elishiselwe ububanzi elikhudlwana elingenalutho elincane, futhi lingasetshenziswa ukukhiqiza ipayipi elishiselwe ububanzi obuhlukahlukene obungenalutho.Kodwa uma kuqhathaniswa nobude obufanayo bepayipi lomthungo oqondile, ubude be-weld bukhuphuka ngo-30 ~ 100%, futhi isivinini sokukhiqiza siphansi.Ipayipi elikhulu eliwububanzi noma eliwugqinsi elishiselwe ngokuvamile lenziwa nge-billet yensimbi ngokuqondile, kuyilapho ipayipi elincane elishiselwe kanye nepayipi elinezindonga ezincane elishiselwe kuphela lidinga ukushiselwa ngokuqondile ngomugqa wensimbi.Khona-ke ngemva kokupholisha okulula, umdwebo wocingo ulungile.Ukuze kuthuthukiswe ukumelana nokugqwala kwepayipi lensimbi, ipayipi lensimbi elijwayelekile (ipayipi elimnyama) lafakwa uthayela.Kunezinhlobo ezimbili zamapayipi ensimbi, i-hot-dip galvanizing kanye ne-electro galvanizing.Ugqinsi lwe-hot-dip galvanizing bukhulu, futhi izindleko ze-electro galvanizing ziphansi.Izinto ezivamile zamapayipi ashiselwe yilezi: Q235A, Q235C, Q235B, 16Mn, 20Mn, Q345, L245, L290, X42, X46, X60, X80, 0Cr13, 1Cr17, 00cr19ni1018b, 9
4. Ipayipi elihlanganisiwe: ipayipi elihlanganisiwe lizibophezele ekukhiqizeni izinhlobo ezahlukene zamapayipi ahlanganisiwe kanye nezinsimbi zensimbi ezinama-seams ajikelezayo namasongo ama-longitudinal, futhi iguqulwa ngesisekelo sokucaciswa okufanayo kanye namamodeli wempahla yepayipi ehlanganisiwe yendabuko.Umsebenzi wokwandisa imingcele yemishini yokugoqa ishubhu ngo-30% ugcwalisa igebe imishini yokugoqa yendabuko engakwazi ukukhiqiza.Ingakwazi ukukhiqiza amapayipi ensimbi ububanzi obungaphezu kuka-400 nokuqina kodonga kuka-8-100 mm.Ipayipi elihlanganisiwe lisetshenziswa kakhulu ku-petroleum, amakhemikhali, ukudluliswa kwegesi yemvelo, ukunqwabelanisa kanye nokuhlinzekwa kwamanzi asemadolobheni, ukufudumeza, ukuhlinzekwa kwegesi kanye namanye amaphrojekthi.Izinto eziyinhloko yi-Q235A, Q345B, 20, 45, 35cimo, 42cimo, 16Mn, njll.
