15Mo3 alloy raj rau boilers yog tuab -walled round tubes ua los ntawm 15Mo3 khoom. Lawv feem ntau yog siv nyob rau hauv cov cua kub ntawm qhov tsawg thiab nruab nrab siab boilers nrog ua hauj lwm pressures tsis tshaj 5.88MPa thiab kub hauv qab no 450 degree, nrog rau cov economizers thiab superheaters ntawm siab - siab boilers. Lawv lub zog tensile yog 450-600MPa, thiab lawv lub zog tawm los yog ntau dua lossis sib npaug rau 270MPa.

15Mo3 siab kub yeeb nkab Features
Siab -Kev Ua Haujlwm Kub: Ua kom zoo txhua yam khoom thiab oxidation tsis kam ntawm qhov kub thiab txias.
Corrosion Resistance: Ua tau zoo tiv thaiv corrosion los ntawm ntau yam tshuaj, nrog rau cov xov xwm corrosive xws li dej, roj, thiab cov kua qaub thiab alkali.
Vuam thiab Machining Performance: Muaj qhov zoo weldability thiab machinability, yooj yim rau kev tsim thiab txheej txheem, thiab tsim nyog rau ntau yam kev tsim khoom thiab kev xav tau.
Daim ntawv thov ntawm 15Mo3 Steel Pipes
15Mo3 alloy kav yog dav siv nyob rau hauv ntau qhov chaw lag luam vim lawv zoo heev - kub, siab - siab, thiab corrosion- cov khoom tiv taus, suav nrog tab sis tsis txwv rau:
Boiler manufacturing: xws li cov khoom tseem ceeb xws li qis-kub superheater headers thiab economizer txhawb thav ntawv (phab ntsa kub tsawg dua lossis sib npaug li 540℃).
Cov hlab ntsha siab: xws li cov thawv ntim tshuaj thiab cov roj cia tank.
Pipeline systems: xws li cov kav dej loj loj (tsim siab tsawg dua lossis sib npaug li 10MPa) thiab lwm cov kav dej uas xav tau qhov kub thiab txias siab.
Petrochemical khoom: xws li catalytic cracking heat exchanger shells thiab sab hauv ntawm hydrogenation reactors (kub tsawg dua los yog sib npaug li 450℃).
Lwm tus: xws li cov cua sov kho cua sov, lub tshuab ua cua sov, thiab lub tshuab ua cua sov, thiab lwm yam khoom siv rau hauv qhov cub.
