316 ipayipi lensimbi engagqwali
Insimbi engagqwali engu-316 iyinsimbi esetshenziswa kakhulu ngaphandle kuka-304 insimbi engagqwali, futhi ingumkhiqizo othuthukisiwe wensimbi engagqwali engu-304.Ngenxa yokwengezwa kwe-Mo, inokumelana nokugqwala okuhle, ukumelana nokugqwala kwasolwandle nasemkhathini, ukumelana nezinga lokushisa eliphakeme kakhulu, nokusebenza kahle kwe-welding.
I-316 insimbi engagqwali inezinhlobonhlobo zezicelo, ikakhulukazi ezisetshenziswa kumakhemikhali, udayi, iphepha, i-oxalic acid, imishini yamanzi olwandle, ukucubungula ukudla, imboni yezokwelapha, ibhawudo, namantongomane.
Ngokungeziwe kuzinhlelo zokusebenza zezimboni, siphinde sibone insimbi engagqwali engu-316 ekuphileni kwansuku zonke, njengezitsha zerayisi zensimbi engagqwali ezivame ukusetshenziswa, izinkomishi zamanzi zensimbi engagqwali, kanye nezindawo zokubala zensimbi engagqwali.I-316 insimbi engagqwali inokumelana nokugqwala okungcono futhi ukumelana ne-asidi, ngakho-ke isetshenziswa kakhulu kwezokwelapha nasembonini.
Izakhiwo ze-316 ipayipi yensimbi engagqwali
1. Ukumelana nokugqwala
Ukumelana nokugqwala kungcono kunensimbi engagqwali engama-304, futhi inokumelana nokugqwala okuhle ekukhiqizeni uginindela nephepha.Futhi insimbi engagqwali engu-316 nayo imelana nokuguguleka yisimo sezulu sezimboni sasolwandle nesinolaka.
2. Ukumelana nokushisa
I-316 insimbi engagqwali (06Cr17Ni12Mo2) inokumelana okuhle kwe-oxidation ekusetshenzisweni kwezikhawu ezingaphansi kuka-871°C (1600°F) kanye nokusetshenziswa okuqhubekayo ngaphezu kuka-927C° (1700°F).Kububanzi obungu-427°C-857°C (800°F-1575°F), kungcono ukungasebenzisi insimbi engagqwali engu-316 ngokuqhubekayo, kodwa insimbi engagqwali inokumelana nokushisa okuhle uma isetshenziswa ngokuqhubekayo ngaphandle kwalolu banga lokushisa.I-carbide precipitation resistance ye-316L yensimbi engagqwali ingcono kune-316 yensimbi engagqwali, futhi izinga lokushisa elingenhla lingasetshenziswa.
3. Ukwelashwa kokushisa
Ifakwe ebangeni lokushisa elingu-850-1050°C, kulandelwa ukucwiliswa ngokushesha, okulandelwa ukupholisa ngokushesha.316 insimbi engagqwali ayikwazi ukwenziwa lukhuni ngokwelashwa okushisa.
4. Ukushisela
I-316 insimbi engagqwali inokushisela okuhle.Zonke izindlela zokushisela ezijwayelekile zingasetshenziselwa ukushisela.Ngokusho kwesicelo, i-316Cb, 316L noma i-309Cb yensimbi engenasici noma ama-electrode angasetshenziselwa ukushisela.Ukuze kutholwe ukumelana nokugqwala okungcono kakhulu, ingxenye eshiselwe yensimbi engagqwali engu-316 idinga ukufakwa ngemuva kokushiselwa.I-post weld annealing ayidingeki uma kusetshenziswa insimbi engagqwali engu-316L.
Ukusetshenziswa kwepayipi lensimbi engagqwali engu-316
Ipayipi lensimbi engagqwali le-316 liwuhlobo lwepayipi lensimbi eliyindilinga eliyindilinga elingenalutho, elisetshenziswa kakhulu kumapayipi ezokuthutha ezimbonini nasezindaweni ezithile zonyaka zesakhiwo ezifana ne-petroleum, imboni yamakhemikhali, ukwelashwa, ukudla, imboni yokukhanya, insimbi yomshini nokunye.Ipayipi lensimbi engagqwali le-316 linokuqukethwe kwekhabhoni okuphezulu okungu-0.03 futhi lingasetshenziswa ezinhlelweni lapho ukucwiliswa ngemuva kokushisela kungenzeki nalapho kudingeka khona ukuguga nokugqwala okukhulu.Inezakhiwo ezinhle zokushisela futhi ingashiswa ngazo zonke izindlela ezijwayelekile zokushisela.Ngenxa yokwengezwa kwesici se-molybdenum Mo, insimbi engagqwali engu-316 ithuthukise kakhulu ukumelana nokugqwala kanye nokumelana nokushisa okuphezulu, ukuqina okuhle kakhulu komsebenzi (okungewona uzibuthe), nokubukeka kwemikhiqizo egoqelwe ngokubanda kunokucwebezela okuhle.Uma kuqhathaniswa nensimbi engagqwali engu-304, ukusebenza komkhiqizo kwenziwe ngcono., intengo iphakeme ngokuqhathaniswa.Manje, imihlobiso eminingi yasekhaya kanye nomhlobiso wezohwebo ophezulu uzosebenzisa insimbi engagqwali engu-316, ngenxa yokumelana kwayo okuqinile kokugqwala, impilo yesevisi izokhula uma iqhathaniswa ne-304 yensimbi engagqwali.
