AI-STM A335 P5amashubhu ensimbi angenamthungo afanele amanzi, umusi, i-hydrogen, uwoyela omuncu, njll. Uma isetshenziselwa umhwamuko wamanzi, izinga lokushisa eliphezulu lokusebenza kwawo ngu-650.℃; Uma isetshenziswa endaweni yokusebenza efana nowoyela omuncu, inokumelana nokugqwala okuhle kwesibabule esisezingeni eliphezulu lokushisa, futhi ivamise ukusetshenziswa ezimweni ezishisa kakhulu zokushisa nesibabule ezingama-288 ~ 550.℃.
Inqubo yokukhiqiza:
1. Ukuginqika okushisayo (ishubhu lensimbi elingenamthungo elikhishiwe) : ishubhu eliyindilinga billet → ukushisisa → ukubhobozwa → ukugoqeka okungama-roll amathathu, ukugoqeka okuqhubekayo noma ukukhishwa → ukuhlubula kweshubhu → ukusika (noma ukunciphisa) → ukupholisa → ukuqondisa → ukuhlolwa komfutho wamanzi (noma ukutholwa kokukhubazeka ) → ukumaka → isitoreji
2. Umdwebo obandayo (oginqikayo) wensimbi engenamthungo: ishubhu eliyindilinga → ukushisisa → ukubhoboza → isihloko → ukubhoboza → ukucosha → ukugcoba → ukugcoba amafutha (i-copper plating) → umdwebo obandayo onamapayipi amaningi (ukugoqeka okubandayo) → ishubhu elingenalutho → ukwelashwa kokushisa → ukuqondisa → amanzi ukuhlolwa kwengcindezi (ukutholwa kwamaphutha) → ukumaka → isitoreji

I-alloy tube iwuhlobo lweshubhu yensimbi engenamthungo, ukusebenza kwayo kuphakeme kakhulu kuneshubhu lensimbi elingenamthungo, ngoba lolu hlobo lweshubhu yensimbi luqukethe u-C owengeziwe, ukusebenza kungaphansi kweshubhu lensimbi elingenamthungo, ngakho-ke ishubhu lengxubevange lisetshenziswa kabanzi. ku-petroleum, i-aerospace, amakhemikhali, amandla kagesi, ubhayela, ezempi nezinye izimboni.
A335 P9iyinsimbi ekwazi ukumelana nokushisa okuphezulu kwe-chromium-molybdenum ekhiqizwa ngokwezinga laseMelika. Ngenxa yokumelana kwayo okuhle ne-oxidation, amandla okushisa aphezulu kanye nokumelana nokugqwala kwe-sulfide, isetshenziswa kabanzi emazingeni okushisa aphezulu kanye nomfutho ophakeme wamapayipi avuthayo naqhuma ezitshalo zokucwenga uphethiloli, ikakhulukazi ipayipi lokushisa eliqondile lesithando sokushisa, izinga lokushisa eliphakathi lingafinyelela ku-550 ~ 600 ℃ .
Insimbi ye-alloy yasekhaya ehambisanayo :1Cr5Mo GB 9948-2006 “Izinga Lepayipi Lensimbi Elingenamthungo Lokuqhekeka Kwephethiloli”

I-A335 P22 iyinsimbi engu-2.25Cr-1Mo Chromium-molybdenum high Temperature ferritic steel yamabhoyili nama-superheaters,I-ASTM A335/A335Mejwayelekile. Ngo-1985, yatshalwa kabusha ku-GB5310 futhi yaqanjwa ngokuthi i-12Cr2MoG. Amanye amazwe anamabanga ensimbi afanayo, njenge-Federal Republic of Germany 10CrMo910 kanye ne-Japan STBA24. Ochungechungeni lwensimbi ye-cr-1Mo, amandla ayo okushisa aphakeme uma kuqhathaniswa, ngaphansi kwezinga lokushisa elifanayo (izinga lokushisa≤580℃) amandla ayo okuphuka kwesikulufu nokucindezeleka okuvunyelwe kungaphezulu ngisho kunensimbi engu-9CR-1Mo, futhi inokucubungula ukusebenza okuhle nokusebenza kokushisela, ipulasitiki enhle ehlala isikhathi eside. Ngakho-ke, isetshenziswe kabanzi endaweni yokusebenza enokhahlo, njengamandla ashisayo, amandla enuzi kanye nemishini ethile ye-hydrogen kumapayipi okushisa ahlukahlukene kanye nemikhumbi yomfutho ophezulu.
Izinga lokushisa elivumelekile: I-A335P22 (SA-213T22) isetshenziswa kakhulu ku-300,600MW nakwamanye amandla amakhulu okushisa kwe-boiler tube wall≤580℃I-superheater kanye nezinga lokushisa le-tube wall & LT;540℃ipayipi le-steam yodonga kanye nekhanda, lolu hlobo lwensimbi luye lwasetshenziswa kabanzi e-United States, eJapane naseYurophu, lunomlando omude wokusebenza ezitshalweni zamandla, ukusebenza okuzinzile, ukusebenza kahle kwenqubo yensimbi evuthiwe.
I-12Cr1MoV steel ingeye-chromium-molybdenum vanadium steel vanadium steel, ikakhulukazi esetshenziselwa ipayipi lensimbi elingu-12Cr1MoV/GB5310. Okusetshenziswa kakhulu, izinga lokushisa elingu-480℃~ 580℃indawo yokushisa ephezulu enenye yezinto ezisetshenziswa kakhulu. I-12Cr1MoVG yensimbi yokushisa yeshubhu yensimbi: isetshenziselwa ikakhulukazi insimbi eyinhloko yeshubhu ye-superheater, unhlokweni kanye nepayipi le-steam le-boiler yomfutho ophezulu okushisa kwayo kweshubhu kungaphansi noma kulingana no-580.℃.
Inqubo yokukhiqiza:Ukuhlolwa kokuqina:
1. Ukuginqika okushisayo (ishubhu lensimbi elingenamthungo elikhishiwe) : ishubhu eliyindilinga billet → ukushisisa → ukubhobozwa → ukugoqeka okungama-roll amathathu, ukugoqeka okuqhubekayo noma ukukhishwa → ukuhlubula kweshubhu → ukusika (noma ukunciphisa) → ukupholisa → ukuqondisa → ukuhlolwa komfutho wamanzi (noma ukutholwa kokukhubazeka ) → ukumaka → isitoreji
2. Umdwebo obandayo (oginqikayo) wensimbi engenamthungo: ishubhu eliyindilinga → ukushisisa → ukubhoboza → isihloko → ukubhoboza → ukucosha → ukugcoba → ukugcoba amafutha (i-copper plating) → umdwebo obandayo onamapayipi amaningi (ukugoqeka okubandayo) → ishubhu elingenalutho → ukwelashwa kokushisa → ukuqondisa → amanzi ukuhlolwa kwengcindezi (ukutholwa kwamaphutha) → ukumaka → isitoreji
Ukupakisha:
Ukupakisha okungenalutho/ukupakishwa kwenqwaba/ukupakishwa kwamakhreyithi/ukuvikela ngokhuni ezinhlangothini zombili zamashubhu futhi kuvikelwe ngokufanelekile ukuze kuhanjiswe ngendlela efanele ulwandle noma njengoba kuceliwe.
