A335 P22 waa 2.25Cr-1Mo Chromium-molybdenum Heerkulka Sare ee birta kuleyliyaha iyo kuleyliyaha sare,ASTM A335/A335Mheerka. 1985kii, waxaa lagu beeray GB5310 waxaana loo bixiyay 12Cr2MoG. Wadamada kale waxay leeyihiin darajooyin bir ah oo la mid ah, sida Jamhuuriyadda Federaalka ee Jarmalka 10CrMo910 iyo Japan STBA24. Taxanaha birta ee cr-1Mo, xooggeeda kulaylku waa mid aad u sarreeya, heerkul isku mid ah (heerkulka≤580℃) xooga jabka furkiisa iyo walbahaarka la ogolyahay ayaa xitaa ka sareeya birta 9CR-1Mo, waxayna leedahay wax qabad wanaagsan oo wax qabad iyo alxanka, caag waara oo wanaagsan. Sidaa darteed, waxaa si weyn loogu isticmaalay jawi shaqo oo adag, sida tamarta kulaylka, tamarta nukliyeerka iyo qaar ka mid ah qalabka hydrogen ee tuubooyinka kuleylka kala duwan iyo maraakiibta cadaadiska sare.
Heerkulka la oggol yahay: A335P22 (SA-213T22) waxaa inta badan lagu isticmaalaa 300,600MW iyo heerkulka kale ee warshadda korontada kuleyliyaha weyn≤580℃kulaylka sare iyo tuubada heerkulka derbiga & LT;540℃tuubada uumiga gidaarka iyo madaxa, noocan oo kale ah ee birta ah ayaa si weyn loogu isticmaalay Maraykanka, Japan iyo Europe, waxay leedahay taariikh dheer oo hawlgal ah ee dhirta korontada, waa waxqabadka xasilloon, habka wanaagsan ee waxqabadka birta bislaaday.
12Cr1MoV steel waxaa iska leh chromium-molybdenum vanadium birta vanadium birta, inta badan loo isticmaalo 12Cr1MoV/GB5310 tuubooyinka birta. Si ballaaran loo isticmaalo, heerkulku waa 480℃~580℃aagga heerkulka sare oo leh mid ka mid ah qalabka ugu badan. 12Cr1MoVG heerkulka adeegga birta: waxaa inta badan loo isticmaalaa birta ugu weyn ee tuubada superheater, madaxa iyo tuubada uumiga kululeeyaha cadaadiska sare kaas oo heerkulka gidaarka tuubada uu ka yar yahay ama la mid yahay 580℃.
Habka wax soo saarka: Imtixaan adag:
1. Duubista kulul (tubo bir ah oo aan kala go 'lahayn) : tuubada wareega ) → calaamadaynta → kaydinta
2. Sawirka qaboobaha (rogid) tuubo bir ah oo aan kala go 'lahayn: tuubo wareeg ah → kululaynta → daloolin → ciwaanka → daadin tijaabada cadaadiska (ogaanshaha cilladaha) → calaamadaynta → kaydinta
Baakad:
Baakad qaawan / xidhmo xidhmo / baakad sanduuq ah / ilaalinta alwaax ee labada dhinac ee tuubooyinka oo si ku habboon loo ilaaliyo u keenista qiimaha badda ama sida la codsado.
