SA213 ityhubhu yebhoyila enoxinzelelo oluphezuluuthotho luityhubhu yebhoyila enoxinzelelo oluphezuluuthotho. Ifanelekile kwiityhubhu zentsimbi ze-ferritic neze-austenitic ezingenamthungo ezinobukhulu obuncinci bodonga kwiibhoyila kunye nee-superheater kunye neetyhubhu zentsimbi ze-austenitic zezixhobo zokutshintsha ubushushu.

Iipayipi zokufudumeza umphezulu ezisetyenziswa kwiibhoyila ezinoxinzelelo oluphantsi noluphakathi (uxinzelelo olusebenzayo ngokubanzi alukho ngaphezu kwe-5.88Mpa, ubushushu bokusebenza bungaphantsi kwe-450℃); zisetyenziswa kwiibhoyila ezinoxinzelelo oluphezulu (uxinzelelo olusebenzayo ngokubanzi lungaphezulu kwe-9.8Mpa, ubushushu bokusebenza buphakathi kwe-450℃ ~ 650℃) ) iityhubhu zokufudumeza umphezulu, ii-superheater, ii-reheater, iityhubhu zoshishino lwe-petrochemical, njl.njl.

I-ASME SA213 T12Umbhobho wentsimbi ye-alloy, okhokelayo kwimibhobho yentsimbi esemgangathweni yaseMelika engenamthungo, usetyenziswa kakhulu kwi-petroleum, kushishino lweekhemikhali, kumbane nakwezinye iindawo zoshishino. Olu hlobo lombhobho wentsimbi lwenziwe ngentsimbi ekumgangatho ophezulu. Emva kokulungiswa ngononophelo kwiinkqubo ezininzi, unamandla aphezulu kwaye unokumelana nokugqwala okuphezulu. Ungahlangabezana neemfuno zokusetyenziswa kwiindawo ezahlukeneyo ezintsonkothileyo.

Inkqubo yayo yokuvelisa iyinkimbinkimbi kwaye intle, kuquka ukunyibilikisa, ukuqengqeleka, ukugqobhoza, ukutsalwa kubanda, unyango lobushushu kunye nezinye iikhonkco. Ngexesha lenkqubo yokuvelisa, umbhobho wentsimbi udlula kwiimvavanyo ezininzi ezingezizo iziphene kunye novavanyo olungonakalisiyo ukuqinisekisa umgangatho wawo ogqwesileyo kunye nokuthembeka. Kukwakho nohlalutyo olwahlukeneyo lweekhemikhali, uhlalutyo lwe-metallographic kunye nezinye iimvavanyo ukuqinisekisa ukuba ukwakheka kwawo, ulwakhiwo lombutho, ukusebenza kunye nezinye izalathisi ziyahlangabezana neemfuno ezisemgangathweni.

Iimpawu zeI-ASME SA213 T12umbhobho wentsimbi ye-alloy ngolu hlobo lulandelayo:
1. Amandla aphezulu: Inamandla aphezulu okutsalwa kunye nendawo yokukhupha, kwaye inokumelana nemithwalo emikhulu kunye neempembelelo.
2. Ukumelana nokugqwala okuphezulu: Inokumelana nokugqwala okukhulu kwiindawo ezahlukeneyo ezintsonkothileyo, ezifana nee-asidi, ii-alkali, iityuwa kunye nezinye izinto zeekhemikhali kunye neendawo ezishushu kakhulu ezifana nobushushu obuphezulu kunye nobushushu obuphantsi.
3. Ukusebenza kakuhle kokuwelda: Yenziwe ngentsimbi ekumgangatho ophezulu, ayichaphazeleki lula kukuqhekeka, iimbobo kunye nezinye iingxaki ngexesha lokuwelda, iqinisekisa umgangatho wokuwelda kunye nokuthembeka.
4. Uluhlu olubanzi lwezicelo: Isetyenziswa kakhulu kwi-petroleum, kwishishini leekhemikhali, kumbane nakwezinye iindawo zoshishino, ezifana nemibhobho yeoyile negesi, iibhoyila, ii-reactors kunye nezinye izixhobo.
