Ipayipi lensimbi engagqwali elingu-316L eliyiqiniso elinezinto eziqinisekisiwe
Ipayipi lensimbi engagqwali le-316 liwuhlobo lwensimbi eyindilinga eyindilinga engenalutho, esetshenziswa kabanzi kumapayipi okudluliselwa kwezimboni kanye nezingxenye zesakhiwo ezifana ne-petroleum, imboni yamakhemikhali, ukwelashwa, ukudla, imboni ekhanyayo, imishini namathuluzi, njll. Ngaphezu kwalokho, lapho amandla okugoba kanye ne-torsional afanayo, isisindo silula, ngakho-ke sisetshenziswa kabanzi ekwenzeni izingxenye zemishini kanye nezakhiwo zobunjiniyela. Iphinde isetshenziswe ngokuvamile ekukhiqizeni izikhali ezihlukahlukene ezivamile, umgqomo, amagobolondo, njll Okunhlobonhlobo: 316 ipayipi yensimbi engagqwali, 316 insimbi engagqwali ipayipi elikhanyayo, 316 insimbi engagqwali ipayipi zokuhlobisa, 316 insimbi engagqwali capillary, 316 insimbi engagqwali ipayipi ashiselwe, 304 ipayipi lensimbi engagqwali.
Okuqukethwe kwekhabhoni ephezulu ye-1316l yepayipi yensimbi engagqwali yi-0.03, engasetshenziswa ezinhlelweni lapho i-annealing ingakwazi ukwenziwa ngemuva kokushisela kanye nokumelana nokugqwala okuphezulu kuyadingeka. Ipayipi lensimbi engagqwali le-316 linokuqukethwe kwekhabhoni okuphezulu okungu-0.03 futhi lingasetshenziswa ezinhlelweni lapho ukudonsa kungeke kwenziwe ngemuva kokushisela kanye nokumelana nokugqwala okuphezulu kuyadingeka.
316 kanye 317 insimbi engagqwali (bona okulandelayo ukuze uthole izakhiwo 317 insimbi engagqwali) kukhona molybdenum equkethe insimbi engagqwali.
Ukusebenza jikelele kwale nsimbi kungcono kune-310 kanye ne-304 yensimbi engagqwali. Ngaphansi kwezimo zokushisa eziphakeme, lapho ukuhlushwa kwe-sulfuric acid kungaphansi kuka-15% nangaphezulu kuka-85%, insimbi engagqwali engu-316 inezinhlobonhlobo zezicelo.
316 insimbi engagqwali plate, eyaziwa nangokuthi 00Cr17Ni14Mo2, ukugqwala ukumelana:
Ukumelana nokugqwala kungcono kunensimbi engagqwali engama-304 futhi kunokumelana nokugqwala okuhle ekukhiqizeni uginindela nephepha.
I-carbide precipitation resistance ye-316 insimbi engagqwali ingcono kune-304 steel stainless, futhi izinga lokushisa elingenhla lingasetshenziswa.
Ipayipi lensimbi engagqwali liwuhlobo lwensimbi eyindilinga ende engenalutho, esetshenziswa kabanzi kumapayipi okudluliselwa kwezimboni afana ne-petroleum, imboni yamakhemikhali, ukwelashwa, ukudla, imboni yokukhanya, amathuluzi emishini kanye nezingxenye zesakhiwo semishini. Ngaphezu kwalokho, lapho ukugoba namandla okugoqa kufana, isisindo silula, ngakho-ke sisetshenziswa kabanzi ekwakhiweni kwezingxenye zemishini kanye nezakhiwo zobunjiniyela. Ibuye isetshenziswe ngokuvamile ekukhiqizeni izikhali ezihlukahlukene ezivamile, umgqomo, amagobolondo, njll. Lolu hlobo lwepayipi lensimbi lingahlukaniswa libe yipayipi yensimbi engenasici kanye nepayipi yensimbi engagqwali eshiselwe (ipayipi elifakwe). Ngokwezinqubo ezihlukene zokukhiqiza, ingahlukaniswa ngezinhlobo ezimbalwa eziyisisekelo: ukugoqa okushisayo, ukukhishwa, ukudweba okubandayo kanye nokugoqa okubandayo. Ngokusho komumo wesigaba, ingahlukaniswa ipayipi eliyindilinga kanye nepayipi elimise okukhethekile. Ipayipi lensimbi eliyindilinga lisetshenziswa kabanzi, kodwa kukhona nezinye izikwele, unxande, isemicircular, hexagonal, unxantathu olinganayo Octagonal kanye namanye amapayipi ensimbi engagqwali amise okukhethekile.
Ukuhlolwa kwe-Hydraulic kuzokwenziwa ipayipi lensimbi elinomfutho woketshezi ukuze lihlole ukumelana nengcindezi kanye nekhwalithi. Ifanelekile uma kungekho ukuvuza, ukumanzisa noma ukunwetshwa ngaphansi kwengcindezi ecacisiwe. Amanye amapayipi ensimbi azophinde abe ngaphansi kokuhlolwa kwe-crimping, ukuhlolwa kokuvutha kanye nokuhlolwa kokucaba ngokuya ngokwezinga noma izidingo zomuntu odingayo.
Ipayipi lensimbi engagqwali engu-304L ingeyendlela yokumaka yamazwe ngamazwe yensimbi engagqwali. 304L ipayipi lensimbi engagqwali -- s30403 (AISI, ASTM)
Uhlobo lwaseShayina oluhambisana ne-304L luyi-00Cr19Ni10
Izici nokusebenza: insimbi enokuqukethwe kwekhabhoni ephansi kune-0Cr19Ni9 inokumelana nokugqwala okuphezulu kwe-intergranular. Kuyingxenye ngaphandle kokwelashwa kokushisa ngemuva kokushisela.
Ukufaka izinombolo kanye nokumelwa kwensimbi
① Izimpawu zezakhi zamakhemikhali zamazwe ngamazwe nezimpawu zezwe zisetshenziselwa ukumela ukwakheka kwamakhemikhali, futhi izinhlamvu zesi-Arabhu zisetshenziselwa ukumelela ingxenye yokuqukethwe:
Isibonelo: i-China, i-Russia 12CrNi3A
②Indlela yokumaka yamazwe ngamazwe yensimbi engagqwali: sebenzisa amadijithi angaguquki ukumela uchungechunge lwensimbi noma izinombolo; Ngokwesibonelo, i-United States, Japan, 300 series, 400 series and 200 series; I-American Iron and Steel Institute isebenzisa amadijithi amathathu ukuhlonza amamaki ajwayelekile ensimbi engagqwali ethambile. Phakathi kwazo, insimbi engagqwali ye-austenitic iboniswa ngezinombolo ze-200 no-300 uchungechunge, futhi insimbi engagqwali ye-ferritic ne-martensitic iboniswa ngezinombolo ze-400 uchungechunge. Insimbi engagqwali, imvula eqinisa insimbi engagqwali kanye nengxubevange ephezulu enokuqukethwe kwensimbi okungaphansi kuka-50% ngokuvamile kusebenzisa igama lelungelo lobunikazi noma igama lokuhweba.
③ Inombolo ye-serial yenziwe ngezinhlamvu zesiLatini nokuhleleka, okubonisa kuphela inhloso.
Ngaphezu kwalokho, insimbi engagqwali engu-316 nayo imelana nomoya wezimboni wasolwandle nolaka. I-316 insimbi engagqwali inokumelana okuhle kwe-oxidation ekusetshenzisweni kwezikhawu ngokumelana nokushisa okungaphansi kuka-1600 ℃ nokusetshenziswa okuqhubekayo okungaphansi kuka-700 ℃.
Ebangeni lama-degree angu-800-1575, kungcono ukungaqhubeki ngokuqhubekayo ku-316 insimbi engagqwali, kodwa lapho insimbi engagqwali engu-316 isetshenziswa ngokuqhubekayo ngaphandle kwalolu hlu lokushisa, insimbi engagqwali inokumelana nokushisa okuhle. I-carbide precipitation resistance ye-316L yensimbi engagqwali ingcono kune-316 yensimbi engagqwali, futhi izinga lokushisa elingenhla lingasetshenziswa.
