AI-STM A335 P5Amashubhu ensimbi angenamthungo afanelekela amanzi, umusi, i-hydrogen, uwoyela omuncu, njll. Uma esetshenziselwa umusi wamanzi, izinga lokushisa eliphezulu lokusebenza kwawo lingu-650℃Uma isetshenziswa ezindaweni zokusebenza ezifana namafutha omuncu, inokumelana okuhle nokugqwala kwesibabule ekushiseni okuphezulu, futhi ivame ukusetshenziswa ezimweni zokugqwala kwesibabule ekushiseni okuphezulu okungu-288~550℃.
Inqubo yokukhiqiza:
1. Ukugoqa okushisayo (ishubhu yensimbi engenamthungo ekhishwe ngaphandle): ishubhu eliyindilinga i-billet → ukushisa → ukubhoboza → ukugoqa okunemiphetho emithathu, ukugoqa okuqhubekayo noma ukukhishwa kweshubhu → ukukhumula ishubhu → usayizi (noma ukunciphisa) → ukupholisa → ukuqondisa → ukuhlolwa komfutho wamanzi (noma ukutholwa kwesici) → ukumaka → isitoreji
2. Ishubhu lensimbi elingenamthungo elidwetshwayo (eligoqekayo) eliyindilinga: ishubhu eliyindilinga eliyindilinga → ukushisa → ukubhoboza → isihloko → ukunamathisela → ukukhahlela → ukugcotshwa ngamafutha (ukucwebezela ngethusi) → ukudweba okubandayo okuneziphambano eziningi (ukugoqa okubandayo) → ishubhu elingenalutho → ukwelashwa kokushisa → ukuqondisa → ukuhlolwa komfutho wamanzi (ukutholwa kwamaphutha) → ukumaka → isitoreji
Izimo Zokusebenza:
Kumadivayisi asemoyeni kanye nawavacuum okucubungula uwoyela ongahluziwe one-sulfur ephezulu,I-ASTM A335 P5Amashubhu ensimbi angenamthungo asetshenziswa kakhulu kumapayipi angaphansi emibhoshongo yomoya kanye neyokushaqa, amashubhu esithando samafutha omoya kanye neyokushaqa, izingxenye zesivinini esikhulu zemigqa yokuguqula uwoyela womoya kanye neyokushaqa kanye neminye ipayipi kawoyela negesi yokushisa okuphezulu equkethe isibabule.
Kumayunithi e-FCC,I-ASTM A335 P5Amapayipi ensimbi angenamthungo asetshenziswa kakhulu kumapayipi okushisa okuphezulu, okulungisa kanye nokuhlanza okubuyiselayo, kanye namanye amapayipi kawoyela negesi esibabule ashisa kakhulu.
Kuyunithi yokupheka ephuzile,I-ASTM A335 P5Ipayipi lensimbi elingenamthungo lisetshenziswa kakhulu epayipini lokuphakela lokushisa eliphezulu phansi kombhoshongo we-coke kanye nepayipi likawoyela negesi lokushisa eliphezulu phezulu kombhoshongo we-coke, ipayipi lesithando phansi kombhoshongo we-coke, ipayipi phansi kombhoshongo we-fracking kanye nelinye ipayipi likawoyela negesi lokushisa eliphezulu eliqukethe i-sulfur.
Ipayipi lensimbi ye-Alloy liqukethe inani elikhulu lezinto ngaphandle kwekhabhoni njenge-nickel, i-chromium, i-silicon, i-manganese, i-tungsten, i-molybdenum, i-vanadium kanye nenani elilinganiselwe lezinye izinto ezamukelwayo njenge-manganese, i-sulfur, i-silicon, ne-phosphorus..
I-ASTM A335 P9 iyipayipi le-ferritic lokushisa eliphezulu elingenamthungo lensimbi ye-alloy ejwayelekile yaseMelika. I-alloy tube uhlobo lwe-seamless steel tube, ukusebenza kwayo kuphakeme kakhulu kune-seamless steel tube ejwayelekile, ngoba lolu hlobo lwe-steel tube luqukethe i-C eningi, ukusebenza kuncane kune-seamless steel tube evamile, ngakho-ke i-alloy tube isetshenziswa kabanzi ku-petroleum, airspace, chemical, power, boiler, amasosha kanye neminye imboni.
I-A335 P9iyinsimbi engashisi kakhulu ye-chromium-molybdenum alloy ekhiqizwa ngokwezinga laseMelika. Ngenxa yokumelana kwayo okuhle kakhulu nokushiswa, amandla okushisa aphezulu kanye nokumelana nokugqwala kwe-sulfide, isetshenziswa kabanzi kumapayipi okushisa aphezulu kanye nokucindezela okuphezulu okuvuthayo kanye nokuqhuma kwezitshalo zokucwenga uphethiloli, ikakhulukazi ipayipi lokushisa eliqondile lesithando sokushisa, izinga lokushisa eliphakathi lingafinyelela ku-550~600℃.

I-A335 P22 iyinsimbi ye-ferritic ye-Chromium-molybdenum engu-2.25Cr-1Mo yokushisa okuphezulu yama-boiler nama-superheater,I-ASTM A335/A335Mejwayelekile. Ngo-1985, yatshalwa kabusha yaba yi-GB5310 yaqanjwa ngokuthi i-12Cr2MoG. Amanye amazwe anezinga elifanayo lensimbi, njengeFederal Republic of Germany 10CrMo910 kanye neJapan STBA24. Ochungechungeni lwensimbi ye-cr-1Mo, amandla ayo okushisa aphezulu kakhulu, ngaphansi kwezinga lokushisa elifanayo (izinga lokushisa).≤580℃) amandla ayo okuphuka kwezikulufo kanye nokucindezeleka okuvumelekile kuphakeme kakhulu kunensimbi engu-9CR-1Mo, futhi inamandla okucubungula nokusebenza kahle kokushisela, i-plasticity enhle eqinile. Ngakho-ke, isetshenziswe kabanzi ezindaweni zokusebenza ezinzima, njengamandla okushisa, amandla enuzi kanye nemishini ethile ye-hydrogen emapayipini ahlukahlukene okushisa kanye nemikhumbi yokucindezela okuphezulu.
Izinga lokushisa elivumelekile: I-A335P22 (SA-213T22) isetshenziswa kakhulu ku-300,600MW kanye nezinye izinga lokushisa lodonga lweshubhu lebhoyila lesitshalo samandla amakhulu.≤580℃izinga lokushisa lodonga lwe-superheater kanye ne-tube & LT;540℃Ipayipi lomusi odongeni kanye nekhanda, lolu hlobo lwensimbi luye lwasetshenziswa kabanzi e-United States, eJapane naseYurophu, lunomlando omude wokusebenza ezitshalweni zamandla, lusebenza kahle futhi lusebenza kahle ngenqubo yensimbi evuthiwe.
Insimbi engu-12Cr1MoV ingeyensimbi ye-chromium-molybdenum vanadium vanadium, esetshenziswa kakhulu kumapayipi ensimbi angu-12Cr1MoV/GB5310. Isetshenziswa kabanzi, izinga lokushisa lingu-480℃~580℃indawo enokushisa okuphezulu enenye yezinto eziningi kakhulu. Izinga lokushisa lensimbi engu-12Cr1MoVG: lisetshenziselwa kakhulu insimbi eyinhloko yeshubhu ye-superheater, i-header kanye nepayipi lomusi webhoyila enomfutho ophezulu lapho izinga lokushisa lodonga lweshubhu lingaphansi noma lilingana no-580℃.
Inqubo yokukhiqiza: Ukuhlolwa kobulukhuni:
1. Ukugoqa okushisayo (ishubhu yensimbi engenamthungo ekhishwe ngaphandle): ishubhu eliyindilinga i-billet → ukushisa → ukubhoboza → ukugoqa okunemiphetho emithathu, ukugoqa okuqhubekayo noma ukukhishwa kweshubhu → ukukhumula ishubhu → usayizi (noma ukunciphisa) → ukupholisa → ukuqondisa → ukuhlolwa komfutho wamanzi (noma ukutholwa kwesici) → ukumaka → isitoreji
2. Ishubhu lensimbi elingenamthungo elidwetshwayo (eligoqekayo) eliyindilinga: ishubhu eliyindilinga eliyindilinga → ukushisa → ukubhoboza → isihloko → ukunamathisela → ukukhahlela → ukugcotshwa ngamafutha (ukucwebezela ngethusi) → ukudweba okubandayo okuneziphambano eziningi (ukugoqa okubandayo) → ishubhu elingenalutho → ukwelashwa kokushisa → ukuqondisa → ukuhlolwa komfutho wamanzi (ukutholwa kwamaphutha) → ukumaka → isitoreji
Ukupakisha:
Ukupakisha okungenalutho/ukupakisha okuhlanganisiwe/ukupakisha amabhokisi/ukuvikela ngokhuni ezinhlangothini zombili zamapayipi futhi kuvikelwe kahle ukuze kuthunyelwe ngendlela efanele olwandle noma njengoba kuceliwe.
