P265GH Carbon Steel Boiler Hlau Yeeb Nkab Kev Qhia Tshwj Xeeb
Txheej txheem cej luam
P265GH yog ib qho uas tsis yog- alloy zoo steel tshwj xeeb tsim los rau lub hom phiaj siab thiab siab kub, tshwj xeeb tshaj yog nyob rau hauv boiler thiab siab hlab ntsha. Cov qib steel no yog txhais los ntawm European tus qauv EN 10216-2 thiab tau siv dav hauv kev tsim hluav taws xob, petrochemical, thiab cov tshuab cua sov.
Cov yam ntxwv tseem ceeb
Hom khoom: Zoo-cov khoom tsis yog- hlau alloy
Daim ntawv thov tseem ceeb: boilers, siab hlab ntsha, thiab siab -kub piping systems
Ua haujlwm kub: Haum rau kev pabcuam kub txog li 400℃(752℃F)
Weldability: Cov khoom siv vuam zoo nrog cov txheej txheem tsim nyog
Corrosion Resistance: Nruab nrab; tej zaum yuav xav tau cov txheej txheem tiv thaiv hauv qhov chaw corrosive

Sau ntawv
P265GH cov kav dej feem ntau yog muab rau hauv cov xwm txheej zoo los xyuas kom meej cov qauv microstructure thiab cov khoom siv kho tshuab.
Tom qab-weld kev kho cua sov yuav tsum tau siv rau qee yam kev siv los txo cov kev ntxhov siab uas seem.
Cov khoom siv no tsis haum rau qhov qis- daim ntawv thov kub uas cuam tshuam rau lub zog ntawm sub- xoom kub yog qhov tseem ceeb.
Kev tshuaj xyuas thiab kev saib xyuas tsis tu ncua raug pom zoo rau cov ntawv thov boiler los saib xyuas qhov muaj peev xwm nkag siab puas ntawm qhov kub siab.
