I-ASTM A213 T22, ekwaziwa ngokuba yi-ASME SA213 T22, ngumbhobho wentsimbi ongenamthungo ophantsi one-chromium eyi-1.90–2.60% kunye ne-molybdenum eyi-0.87–1.13% njengezinto eziphambili zokudibanisa, ezisetyenziswa kakhulu kwiibhoyila, kwii-superheaters, nakwii-heat exchangers kwiindawo ezinobushushu obuphezulu, ezinoxinzelelo oluphezulu.
Isikhundla se-UNS yi-K21590.
Intsimbi yeBotopngumthengisi weepayipi zentsimbi ye-alloy ochwephesha nothembekileyo kunye nomthengisi wempahla eTshayina, okwaziyo ukubonelela ngokukhawuleza ngeepayipi zentsimbi ye-alloy ekumgangatho ophezulu kwiiprojekthi zakho.
Zonke iimveliso zixhasa ukuhlolwa ngumntu wesithathu, kwaye singabonelela ngezinto zokufakelwa kwe-alloy ezifanayo ezifana neengqiniba kunye nezinye izixhobo zepayipi.
Imibhobho yentsimbi ye-T22 mayiyenziwe yiinkqubo engenamthungokwaye kufuneka igqitywe ngokushushu okanye ngokubandayo, njengoko kuchaziwe.
Zonke iipayipi zentsimbi ze-T22 mazifudunyezwe ukuze kulungiswe ubushushu, nto leyo ekufuneka yenziwe ngokwahlukeneyo kwaye yongezwe ekufudumaleni ukuze kwenziwe ubushushu.
Iindlela zonyango lobushushu ezivumelekileyo zi-annealing epheleleyo okanye e-isothermal, okanye zilungelelanise kwaye zifudumale.

| Uvavanyo lokuvutha | Uvavanyo olunye lokutshaya kufuneka lwenziwe kwiisampuli ezivela kwisiphelo ngasinye setyhubhu enye egqityiweyo, kungekhona leyo isetyenziselwa uvavanyo lokutshaya, ukusuka kwilothi nganye. | |
Ngaphezu koko, iipropati zoomatshini ze-ASTM A213 T22 ziyafana nezo ze-T2, T5, T5c,T11, T17, kunye neT21.
Ubukhulu beetyhubhu ze-ASTM A213 T22 kunye nobukhulu bodonga zihlala zixhotyiswe ngobubanzi bangaphakathi obuqala kwi-3.2 mm ukuya kububanzi bangaphandle obuyi-127 mm, kunye nobukhulu bodonga obuncinci obuqala kwi-0.4 mm ukuya kwi-12.7 mm.
Kakade ke, ukuba iprojekthi yakho ifuna ezinye iisayizi, oko kuvumelekile, lo gama nje zonke ezinye iimfuno ezifanelekileyo kwi-ASTM A213 ziyafezekiswa.
Iimfuneko zokunyamezelana ezinobukhulu be-ASTM A213 ziyafana kwaye zidweliswe kuluhluImibhobho yentsimbi ye-alloy ye-T11Ungazicofa ukuze uzibone ukuba kuyimfuneko.
Imibhobho yentsimbi engenamthungo ye-ASTM A213 T22 isetyenziswa kakhulu kwiimeko zenkonzo zobushushu obuphezulu kunye noxinzelelo oluphezulu, ingakumbi kumashishini okuvelisa umbane, iikhemikhali zepetroli, kunye neoyile negesi.
Izicelo eziqhelekileyo ziquka:
Iityhubhu zebhoyilazisetyenziselwa ii-superheater, ii-reheater, kunye ne-economizers kwizityalo zamandla.
Izitshintshi zobushushuzisetyenziswa kwizityalo zeekhemikhali kunye neekhemikhali.
Iityhubhu zefenitshalazisetyenziswa kwiindawo zokusebenzisa izitofu ezishushu kakhulu.
Iipayipi zomphungazisetyenziselwa ukuthwala umphunga oxinzelelweyo ophezulu kwimizi-mveliso.
