I-GB/T 6479-2013 imele izinto ezi-10#/20#, iityhubhu zokutshintsha ubushushu i-SA179/SA210/SA192, njl.njl., iityhubhu zoomatshini i-GB/T 8162 zimele izinto ezi-10#/20#/Q345/42CrMo, i-EN10210 imele izinto ezi-S355JOH/S355J2H, iityhubhu zesilinda yegesi i-GB1 8248, zimele izinto ezi-34CrMo4/30CrMo.
GB/T 5310-2017 yinkcazo yobuchwephesha yeepayipi zentsimbi engenamthungo zeebhoyila ezinoxinzelelo oluphezulu kumgangatho wesizwe saseTshayina. Iyasebenza ekwenziweni kweebhoyila zomphunga, iipayipi, kunye nezinye izixhobo ezisebenza kuxinzelelo oluphezulu nangaphezulu.
Lo mgangatho ugubungela iintlobo ngeentlobo zeentsimbi ze-alloy, apho i-12CrMoG kunye ne-15CrMoG ziintsimbi ezimbini ze-alloy ezisetyenziswa kakhulu kwaye zinezicelo ezininzi kunye neenzuzo ezibalulekileyo.
12CrMoGyintsimbi ye-chromium-molybdenum alloy enokumelana okuhle kakhulu nobushushu obuphezulu kunye nokumelana ne-oxidation. Ifanelekile kwii-boiler superheaters, ii-reheaters, ii-steam piping, kunye nezinye izinto ezisebenza kumaqondo obushushu angaphantsi kwama-540°C. Iingenelo zayo ziquka amandla aphezulu okuqhekeka kunye namandla okunyamezela, kunye nokukwazi ukugcina iipropati zoomatshini ezizinzileyo phantsi kweemeko zobushushu obuphezulu kunye noxinzelelo oluphezulu. Ikwanayo nokudityaniswa okuhle kunye nokucutshungulwa, okwenza kube lula ukuyenza nokuyifakela.
15CrMoGyenye intsimbi ye-chromium-molybdenum alloy esebenza kakuhle kune-12CrMoG. Ifanelekile kwiindawo zebhoyila ezinoxinzelelo oluphezulu ezisebenza kumaqondo obushushu angaphantsi kwama-550°C. Le nto inika amandla aphezulu obushushu obuphezulu kunye nokumelana ne-oxidation, nto leyo eyenza ukuba ifaneleke ngakumbi ekuveliseni iindawo ezibalulekileyo ezifana nee-boiler headers kunye neepayipi eziphambili zomphunga. I-15CrMoG ikwanokumelana okuhle kakhulu nokugqwala kwe-hydrogen, ithintela ngokufanelekileyo ukuwohloka kwezinto kwiindawo ze-hydrogen ezinobushushu obuphezulu kunye noxinzelelo oluphezulu kwaye yandisa ubomi bezixhobo.
Ezi ntsimbi zimbini ze-alloy zisetyenziswa kakhulu kwizixhobo ezisebenzisa ubushushu obuphezulu, ezisebenzisa uxinzelelo oluphezulu kumashishini kagesi, i-petrochemical, kunye neekhemikhali. Iingenelo zazo zibonakala kakhulu kwezi zinto zilandelayo: Okokuqala, zibonisa iimpawu ezintle kakhulu zoomatshini ezisebenzisa ubushushu obuphezulu, ezizivumela ukuba zikwazi ukumelana neemeko zokusebenza ezisebenzisa ubushushu obuphezulu, ezisebenzisa uxinzelelo oluphezulu ixesha elide; okwesibini, zibonisa uzinzo oluhle kakhulu lwezakhiwo, nto leyo eyenza zingachaphazeleki kakhulu kukuwohloka kwesakhiwo ngexesha lenkonzo yexesha elide; okwesithathu, zibonisa ukudityaniswa kakuhle kunye nokucutshungulwa, nto leyo eququzelela ukwenziwa kunye nokugcinwa; kwaye ekugqibeleni, ukusetyenziswa kwazo kuphucula kakhulu ukhuseleko kunye nokuthembeka kwezixhobo, kunciphisa ixesha lokungasebenzi kunye nokugcinwa, kwaye kunciphisa iindleko zokusebenza.
Ezinye iintsimbi ze-alloy ezisebenzayo kakhulu ziyafumaneka ukuhlangabezana neemfuno zobushushu obahlukeneyo, uxinzelelo, kunye neendawo ezirhabaxa.
20G(Intsimbi yeKhabhoni)
Nangona i-20G ingeyontsimbi ye-alloy, sisixhobo esibalulekileyo esidweliswe kwi-GB/T 5310-2017 njengentsimbi yesakhiwo yekhabhoni esemgangathweni ophezulu, esetyenziswa kakhulu kwiindawo zebhoyila ezinobushushu obuphantsi ezifana ne-economizers kunye ne-superheaters ezinobushushu obuphantsi. Iingenelo zayo ziquka iindleko eziphantsi kunye neempawu ezibalaseleyo zoomatshini kunye nokuwelda. Ifanelekile kwiipayipi zebhoyila ezinoxinzelelo oluphakathi noluphantsi kunye namaqondo obushushu okusebenza angadluli kwi-450°C.
12Cr1MoVG
I-12Cr1MoVG yintsimbi ye-chromium-molybdenum-vanadium alloy enamandla aphezulu obushushu kunye nokumelana ne-oxidation xa kuthelekiswa ne-12CrMoG kunye ne-15CrMoG. Ukongezwa kwe-vanadium kuphucula amandla okuqhekeka kunye namandla okunyamezela kwento, okwenza ukuba ikwazi ukugcina ukusebenza okuzinzileyo kwiindawo ezishushu kakhulu ixesha elide. I-12Cr1MoVG ifanelekile kwii-superheaters ze-boiler ezinoxinzelelo oluphezulu, ii-reheaters, kunye neepayipi eziphambili zomphunga ezinamaqondo obushushu angaphantsi kwama-570°C.
25MnG(Intsimbi yeManganese Low Alloy)
I-25MnG yintsimbi ethambileyo ene-alloy ephantsi enomxholo ophezulu we-manganese, enika amandla aphuculweyo kunye nokuqina xa kuthelekiswa ne-20G. Inamandla aphezulu okuvelisa kunye namandla okutsalwa ngelixa igcina ukudityaniswa okuhle. I-25MnG ifanelekile kwizixhobo zebhoyila ezinobushushu obuphezulu kancinci bokusebenza, njengeetyhubhu ze-superheater kunye neepayipi zomphunga kwiibhoyila ezinoxinzelelo oluphakathi. Ubushushu bayo bokusebenza ngokubanzi abudluli kwi-480°C. Kwizixhobo zebhoyila ezineemfuno zobushushu obuphantsi, intsimbi yekhabhoni ye-20G iyakhethwa ngenxa yokusebenza kwayo okungabizi kakhulu. Xa amaqondo obushushu esondela kwi-450°C, i-25MnG iyindlela. Kumaqondo obushushu aphakathi kwe-450-500°C, kucetyiswa i-15MoG. Kumaqondo obushushu aphakathi kwe-500-530°C, i-20MoG iyindlela efanelekileyo ngakumbi. Ezi nqanaba ezingezizo ze-alloy kunye ne-alloy ephantsi, zidibene nentsimbi ene-alloy ephezulu, zinokuphucula iindleko zokwenziwa kwebhoyila ngelixa zigcina ukusebenza.
