ASTM A213 T9 Almloy Hlau Studded Fin Yeeb Nkab

ASTM A213 Qib T9 yog qhov nruab nrab hauv nruab nrab- chromium alsoy ntawm kev siv ntev {} -}} kev lag luam siab. Nws ntaus tau zoo heev ntawm qhov siab - lub zog tseem ceeb, thiab tus nqi tseem ceeb, thiab petrochemical rauv yas thiab pettrchemical rauv yas. Txawm hais tias hloov nyob rau hauv qee cov ntawv thov los ntawm cov qib tshiab steel zoo li T91, uas muaj kev ua haujlwm zoo dua, T9 tseem dav siv ntau yam khoom siv thiab tsim qauv.

 

Kev sib piv nrog lwm cov qib kawm

 

Kev sib piv nrog T5 (5cr {{4 4}} 0.5mo): T9 cov ntsiab lus chromium thiab molybdenum lub zog thiab oxidation tsis kam piv rau T5.

 

Kev sib piv nrog T11 (1.25Co) / t22 (2.25Co): T9 cov ntsiab lus Chromium yog siab dua li ntawm T11 thiab Corrosion Kuj, tab sis kuj yog tus nqi ntau dua.

 

Piv rau T91 (9Cr - 1mo {{v {} n} nb): v) thiab niobium (nb). Los ntawm nag lossis daus muaj zog, nws siab- lub zog kub yog qhov zoo tshaj plaws rau qhov ntawd. Nws yog tam sim no yog ib qho khoom siv uas nyiam tshaj rau cov neeg ua haujlwm thiab cov nroj tsuag ultra-supercritical. T9 tuaj yeem suav tau tias yog T91.

Txhim Kho Tshav Kub:

13CR cov tub ntxhais muab ntxiv qhov chaw ntxiv, txhim kho kev hloov kho tshav kub kub.

Haum rau Radiant ntu hauv qhov cub uas qhov siab thermal conductivity yog qhov tseem ceeb heev.

Siab - kub tsis kam:

ASTM A213 T9 Alloy Steel withstcts tour ntsuas kub txog 650 degree.

13crips tiv thaiv oxidation thiab scaling, txawm nyob hauv ib puag ncig.

Corrosion Kuj:

Chromium cov ntsiab lus nyob rau hauv lub hauv paus tube thiab studs txhim kho kom xeb nyob rau hauv ib puag ncig hnyav, suav nrog kev ua pa nrog roj thiab commustion beproducts.

Yam ruaj khov:

Muaj cov neeg kho mob zoo sib txuas ntawm lub hauv paus tube thiab cov tub ntxhais kawm kom ntev - lub sij hawm kev ua haujlwm nyob rau hauv thermal cycling thiab kev co.

 

Cov Ntawv Thov

Radiant Coils hauv Furnaces thiab Cua Sov:

Siv nyob rau hauv radiant ntu kom nqus tau cua sov los ntawm kev sib txuam roj thiab hloov nws mus rau cov dej ua kua.

Boiler Tshuab:

Qhov zoo tagnrho rau dej raj boilers hauv lub hwj chim nroj tsuag thiab kev ua kom zoo.

Petrochemical thiab Refining Kev Lag Luam:

Feem ntau siv nyob rau hauv cov txheej txheem tso cua sov, cov kws kho kom zoo nkauj, thiab tawg ua kom tawg.

Siab - kev hloov pauv kub:

Haum rau kev rov qab cov ntawv thov rov qab ua cov txheej txheem muaj.
