Amapayipi ensimbi engagqwali aluhlobo lwepayipi elenziwe ngensimbi engenacala, impahla eyaziwa ngokumelana kwayo ekugqwaneni, amandla aphezulu, kanye nezinto zokuhlanza ezilula. Lawa mapayipi asetshenziswa kabanzi kwizimboni ezahlukahlukene, kufaka phakathi ukwakhiwa, amakhemikhali, ukudla kanye nemithi.
Izinhlobo zamapayipi ensimbi angenasici
Amapayipi ensimbi engagqwali angahlukaniswa ezigabeni eziningana ezisuselwa ekubusweni kwazo ezibonakalayo:
Amapayipi ensimbi engagqwali Zivame ukusetshenziswa ekusebenzeni kokudla, kwamakhemikhali, kanye nokwekhemikhali.
Izinzuzo:
Ukumelana nokugqwala okuphakeme
Ukuhlehlisa okuhle nokwakheka
Ukufudumala okuhle
Okubi:
Izindleko eziphakeme ziqhathaniswa nezinye izinhlobo zensimbi ezingenasici
Ukususwa ekugxumeni kokuhlangana kwezixazululo ze-chloride
Izinto ezijwayelekile:
304: insimbi esetshenziswa kakhulu ye-auntenitic, enikeza ukulinganisela kwezakhiwo
316: ukumelana okuthuthukisiwe kokugqwala kwe-chloride, kufanelekile kwizinhlelo zokusebenza zamanzi olwandle
I-301: Inketho ephansi yezindleko, kepha ngokumelana nokugqwala okuphansi okuphansi
Amapayipi ensimbi engagqwali: Lawa mapayipi aqukethe i-chromium futhi ayaziwa ngezindleko zawo eziphansi uma kuqhathaniswa nezinhlobo ze-auntenitic. Kodwa-ke, ukumelana kwabo nokugqwala ngokuvamile kuphansi. Zisetshenziswa ngokuyinhloko kwizicelo zokwakha kanye nokuhlobisa.
Izinzuzo:
Izindleko eziphansi ziqhathaniswa nensimbi e-auntenitic engagqwali
Izakhiwo zamabuthe, ezivumela ukukhonjwa okulula
Okubi:
Ukumelana okuphansi okuphansi, ikakhulukazi ezindaweni ezine-acid
Amandla anciphise ngokuqhathaniswa nensimbi e-auntenitic engagqwali
Izinto ezijwayelekile:
I-430: Insimbi evame kakhulu engenasici, inikeza inketho engabizi kakhulu
409: Kuthuthukiswe ukumelana ko-oxidation, kufanele izinhlelo zokushisa okuphezulu ezifana nezinhlelo zokuqeda imoto
Amapayipi ensimbi engagqwali: Lawa mapayipi aqukethe i-chromium nekhabhoni, akhombisa amandla aphezulu nobulukhuni. Kodwa-ke, ukumelana kwabo nokugqwala ngokuvamile kuphansi. Zisetshenziselwa kakhulu amathuluzi okukhiqiza kanye nezinto zemishini.
Izinzuzo:
Amandla aphezulu nobulukhuni, ukuhlinzeka ngokumelana okuhle kakhulu kokugqoka kanye nokubekezelela umthelela
Ukumelana okuhle kwamazinga okushisa aphezulu
Okubi:
Ukumelana nokugqwala okumpofu kuqhathaniswa nezinhlobo ze-auntenitic nezenhlaka
I-couctility ephansi, okwenza ukwakha inselelo enkulu
Izinto ezijwayelekile:
I-420: Insimbi evame kakhulu ye-martensitic, enikeza ukulinganisela kwamandla nobulukhuni
440: Amandla aphezulu nobulukhuni, elungele ukukhiqiza amathuluzi anembe ephezulu kanye nezinto
Amapayipi ensimbi angenacala Zivame ukusetshenziswa embonini kawoyela negesi.
Izinzuzo:
Ukumelana nokugqwala okuphakeme okuqhathaniswa nensimbi ye-auntenitic engagqwali, ikakhulukazi ezixazululweni ze-chloride
Amandla aphezulu kunensimbi engenacala, enikeza ukumelana okuhle kokuqina kanye nokubekezelela umthelela
Okubi:
Izindleko eziphakeme uma ziqhathaniswa nensimbi ye-auntenitic ne-Ferritic engagqwali
Kuyinselele ngokwengeziwe ukwenza lokhu, kudinga imishini namasu akhethekile
Izinto ezijwayelekile:
I-21Cr-6NI: Insimbi evame kakhulu ye-duplex engagqwali, enikeza ukulinganisela kwezakhiwo
I-22cr-8ni: ukumelana okuthuthukile ku-chloride corrosion, efanelekile kwizinhlelo zokusebenza zamanzi olwandle
Amapayipi we-nickel-alloy: Lawa mapayipi enziwa ngama-alloys asuselwa ku-nickel, enikeza ukumelana nokugqwayiza okuhlukile kanye nekhono lokumelana nezimo ezinzima. Zivame ukusetshenziswa ezinhlelweni ze-aerospace, zasolwandle kanye nasezinhlelo zokusebenza zamandla enuzi.
Izinzuzo:
Ukumelana ngokweqile kokugqwala, okukwazi ukubekezelela izindawo ezahlukahlukene ezinolaka
Amandla amahle kakhulu kanye nokumelana okushisa okuphezulu
Okubi:
Izindleko eziphakeme kakhulu ngokuqhathaniswa nezinye izinhlobo zensimbi engenasici
Izinqubo eziyinkimbinkimbi zokuqamba, ezidinga imishini ekhethekile nobuchwepheshe
Izinto ezijwayelekile:
Hastelloy c-276: isetshenziswa kabanzi ukumelana kwayo okubanzi
UConfel 625: Amandla aphezulu kanye nokumelana nezimo ezedlulele
I-Monel 400: Ukumelana Kahle Kwizixazululo Zasolwandle Nezixazululo ze-Chloride
