A335 P22 waa bir ferritic heerkul sare ah oo 2.25Cr-1Mo ah oo loogu talagalay kuleyliyeyaasha iyo kuleyliyeyaasha sare,ASTM A335/A335MHeerka. Sannadkii 1985, waxaa lagu beeray GB5310 waxaana loogu magac daray 12Cr2MoG. Dalalka kale waxay leeyihiin darajooyin bir ah oo la mid ah, sida Jamhuuriyadda Federaalka ee Jarmalka 10CrMo910 iyo Japan STBA24. Taxanaha birta cr-1Mo, xooggeeda kuleylku waa mid aad u sarreeya, heerkul isku mid ah (heerkulka)≤580℃) Xoogga jabitaanka boolalkiisa iyo cadaadiska la oggol yahay xitaa wuu ka sarreeyaa birta 9CR-1Mo, wuxuuna leeyahay waxqabad wanaagsan oo habayn iyo waxqabad alxan, balaastig waara oo wanaagsan. Sidaa darteed, si weyn ayaa loogu isticmaalay jawiga shaqada ee adag, sida awoodda kulaylka, awoodda nukliyeerka iyo qaar ka mid ah qalabka haydarojiinta ee tuubooyinka kala duwan ee kululaynta iyo weelasha cadaadiska sare leh.
Heerkulka la oggol yahay: A335P22 (SA-213T22) waxaa inta badan loo isticmaalaa 300,600MW iyo heerkulka derbiga ee tuubada kuleyliyaha ee warshadda korontada ee awoodda weyn leh.≤580℃Heerkulka darbiga tuubada iyo kuleyliyaha sare & LT;540℃Tuubada uumiga derbiga iyo madaxa, noocan birta ah ayaa si weyn looga isticmaalaa Mareykanka, Japan iyo Yurub, waxay leedahay taariikh dheer oo ku saabsan shaqada warshadaha korontada, waa waxqabad deggan, waxqabad wanaagsan oo habka birta qaangaarka ah.
Birta 12Cr1MoV waxay ka tirsan tahay birta vanadium ee birta chromium-molybdenum, oo inta badan loo isticmaalo tuubooyinka birta ah ee 12Cr1MoV/GB5310. Si ballaaran ayaa loo isticmaalaa, heerkulku waa 480℃~580℃Aag heerkul sare leh oo leh mid ka mid ah agabka ugu badan. Heerkulka adeegga tuubada birta ah ee 12Cr1MoVG: waxaa inta badan loo isticmaalaa birta ugu weyn ee tuubada superheater, madaxa iyo tuubada uumiga ee kuleyliyaha cadaadiska sare leh oo heerkulkiisa darbiga tuubada uu ka yar yahay ama la mid yahay 580℃.
Habka wax soo saarka: Tijaabada Adkaanta:
1. Duub kulul (tuubo bir ah oo aan kala go 'lahayn oo la soo saaray): tuubo wareegsan oo duuban → kuleyl → daloolin → saddex-duub oo iskutallaab ah, duubid joogto ah ama fidin → xoqidda tuubada → cabbirka (ama yaraynta) → qaboojinta → toosinta → tijaabada cadaadiska biyaha (ama ogaanshaha cilladaha) → calaamadaynta → kaydinta
2. Tuubo bir ah oo aan kala go 'lahayn oo sawir qabow (rogid ah): tuubo wareegsan oo billet ah → kuleyl → daloolin → cinwaan → daadinta → qajaar → saliidayn (dahaadhka naxaasta ah) → sawir qabow oo badan (rogid qabow) → tuubo madhan → daawaynta kulaylka → toosinta → tijaabada cadaadiska biyaha (ogaanshaha cilladaha) → calaamadaynta → kaydinta
Baakad:
Baakad qaawan/xidhmo baakad/xirmo baakad/ilaalin alwaax ah labada dhinac ee tuubooyinka oo si habboon loo ilaaliyo si loogu keeno meel u qalanta badda ama sida loo codsado.
