Simbi ye12Cr1MoV ndeyesimbi yechromium-molybdenum vanadium steel vanadium, inonyanya kushandiswa pa12Cr1MoV/GB5310 steel pipe. Inoshandiswa zvakanyanya, ndiyo tembiricha iri mu480.℃~580℃nzvimbo inodziya zvakanyanya ine chimwe chezvinhu zvakawanda. 12Cr1MoVG tembiricha yebasa rechubhu yesimbi: inonyanya kushandiswa pasimbi huru yechubhu ye superheater, header uye pombi yesteam yebhoyira ine pressure yakakwira ine tembiricha yemadziro echubhu iri pasi kana kuti yakaenzana ne580℃.
Maitiro ekugadzira: Kuedza kweKuoma:

2. Chubhu yesimbi isina musono inodhonzwa nechando: chubhu yakatenderera → kupisa → kuboorwa → musoro → kunamira → kunamira → kunamira mafuta (kuputira mhangura) → kunamira nechando (kudhonza kunotonhora) → chubhu isina chinhu → kurapwa nekupisa → kunamira → kuyedza kumanikidzwa kwemvura (kuona zvikanganiso) → kunamira → kuchengetera
Kurongedza:
