Imikhiqizo Izigaba

Ukwakheka kwamakhemikhali: 22% chromium, 5% nickel, 3% molybdenum, kanye 0.18% nitrogen. Izakhiwo zikamshini: Amandla Aqinile:620MPa, Amandla Esivuno: 450MPa, Ukwelulwa:25%.

Insimbi engagqwali ye-310S ifaneleka ngokukhethekile ukusetshenziswa ezindaweni ezishisa kakhulu, isibonelo ezinhlelweni ezifana neziko zokushisa ukushisa, amakamelo omlilo, ama-boilers, izinto zamakhemikhali, izishintshisi zokushisa, namashubhu esithandweni somlilo.

Ukwakheka: 409 insimbi engagqwali iyinsimbi engagqwali ye-austenitic enokuqukethwe okuphezulu kwe-chromium (cishe u-10.5-11.7%) kanye nokuqukethwe kwekhabhoni ephansi.Lokhu kwakheka kwenza insimbi engagqwali engu-409 ingabi-zibuthe futhi imelane nokugqwala.

I-904L iyinsimbi engagqwali eyi-super-austenitic enokumelana nokugqwala okuphezulu kakhulu, ikakhulukazi ezindaweni eziqukethe ama-ion e-chloride. Le nto iqukethe i-nickel ephezulu kanye nokuqukethwe kwe-molybdenum, kanye nenani elilinganiselwe lethusi, elinikeza ukumelana nokugqwala okuhle kakhulu ezindaweni ezine-acidic, alkaline, ne-saline.904L insimbi engagqwali isetshenziswa kabanzi embonini yamakhemikhali, i-petroleum, ukwenza iphepha, ukucubungula ukudla, ubunjiniyela basolwandle kanye nezinye izimboni.

I-Hastelloy C-276 iyingxubevange esekelwe ku-nickel equkethe izakhi ezifana ne-molybdenum, i-chromium ne-tungsten, eyinikeza ukumelana nokugqwala okuhle kakhulu ezindaweni ezigqwalile ezihlukene, ezifanele ukusetshenziswa ezindaweni eziqukethe i-chloride. I-S32760 (Eyaziwa nangokuthi i-Super Dual-phase Steel 2507) iyinsimbi engagqwali enezigaba ezimbili ehlanganisa okuhle kwe-austenite nensimbi engagqwali yomzimba, enamandla aphakeme kanye nokumelana nokugqwala okungcono kwamabala kanye nokumelana nokugqwala kwegebe.

Ukwakheka kwamakhemikhali: I-Incoloy 800 iyingxubevange ye-nickel-iron-chromium equkethe ingxenye ephezulu ye-nickel (cishe 30-35%), i-chromium (cishe 19-23%) nensimbi (cishe 39-45%).Iqukethe nenani elincane lekhabhoni, i-manganese, i-silicon nethusi.

I-TP304L Inguqulo yepayipi yensimbi engagqwali engu-304L, iyinsimbi engagqwali ene-carbon austenitic ephansi, ingeyezinga le-ASTM A312. Insimbi engagqwali engu-304L iyinguqulo ye-carbon ephansi ye-304 yensimbi engagqwali, futhi okuqukethwe kwayo kwekhabhoni kulawulwa ngaphansi kuka-0.03%, okukunikeza ukumelana nokugqwala okungcono kwe-intercrystalline ngesikhathi se-welding.304L insimbi engagqwali isetshenziswa kabanzi ezinhlelweni ezidinga ukumelana nokugqwala nokumelana nokushisa okuphezulu, njengamakhemikhali, i-petroleum, ukucubungula amandla ekhemisi, i-nuclear energy processing, i-nuclear

I-TP304 iyinsimbi engagqwali ye-austenitic yochungechunge lwe-300 yensimbi engagqwali futhi isetshenziswa kabanzi emikhakheni yezimboni, ikakhulukazi ezinhlelweni ezidinga ukumelana nokugqwala kanye nokumelana nezinga lokushisa eliphezulu. I-TP 304 insimbi engagqwali iqukethe u-18% we-chromium kanye ne-nickel engu-8%, eyinika ukumelana nokugqwala okuhle kanye nezakhiwo ezinhle zokusebenza. Ipayipi elishiselwe le-TP 304 insimbi engagqwali lisetshenziswa kakhulu embonini ukuthutha uketshezi, igesi kanye nesitimu, kanye nezinto zokwakha embonini yamakhemikhali, kaphethiloli, ekucubunguleni ukudla, ezimbonini zezemithi nezenuzi.

I-TP317H Inqubo yokukhiqiza yamapayipi ensimbi engagqwali ashiselwe ibandakanya izinyathelo eziningi zokuqinisekisa ukuthi ikhwalithi yomkhiqizo wokugcina ihlangabezana nezindinganiso ezithile zezimboni kanye nezidingo zohlelo lokusebenza.

I-TP347H Ipayipi elishiselwe lensimbi engagqwali iyinsimbi ekhethekile ye-austenitic, iyingxenye yochungechunge lwensimbi yamandla ashisayo, elinokuqina okuhle kokushisayo kanye nokumelana nokugqwala kwe-intercrystalline. Lokhu okubalulekile kulungele ukusetshenziswa emazingeni okushisa aphezulu, njengamashubhu e-boiler superheater, amashubhu afudumeza kabusha, amapayipi esitimu, nezishintshisi zokushisa ze-petrochemical. I-TP347H Ukusebenza okuhle kokushisela kwepayipi elishiselwe lensimbi engagqwali, elivumela ukuthi ligcine ubuqotho bezinto ezibonakalayo kanye nokumelana nokugqwala ngesikhathi senqubo yokukhiqiza.

Ipayipi lokudlulisa ukushisa kwensimbi engagqwali luhlobo lwepayipi elisetshenziswa kuma-heat exchangers. Yenziwe ngezinto zensimbi engagqwali futhi inokumelana nokugqwala okuhle, ukumelana nokushisa okuphezulu namandla emishini.Amapayipi okudlulisa ukushisa ensimbi engenasici asetshenziswa kakhulu kumakhemikhali, i-petroleum, ukudla, imithi, amandla, imishini, i-aerospace nezinye izimboni zokudlulisa ukushisa nokuthuthukisa ukusebenza kahle kokushintshanisa ukushisa.

Ukufakwa kwamapayipi ensimbi engagqwali kubhekisela ekufakweni kwamapayipi okuhlukahlukene okwenziwe ngezinto zensimbi engagqwali, ezisetshenziswa kabanzi ezimbonini nasezindaweni zomphakathi.Ukufakwa kwamapayipi ensimbi engagqwali kuvame ukusetshenziselwa ukuthutha uketshezi, amagesi, umusi kanye neminye imidiya, futhi ibe nezici zokumelana nokugqwala, ukumelana nokushisa okuphezulu, amandla aphezulu, nempilo ende yesevisi.
