Hauv cov chaw lag luam kub thiab siab, kev xaiv cov khoom siv yog qhov tseem ceeb rau kev nyab xeeb ntawm cov khoom siv thiab kev ua haujlwm zoo. T91 thiab P91, ua ob lub hlau martensitic uas tiv taus cua sov, feem ntau siv rau hauv kev tsim hluav taws xob, petrochemical, thiab lwm yam lag luam. Txawm hais tias lawv lub npe zoo sib xws thiab cov tshuaj sib xyaw ua ke zoo sib xws, lawv cov yam ntxwv kev ua tau zoo thiab cov xwm txheej ntawm daim ntawv thov qhia txog qhov sib txawv tseem ceeb.

Qhov Txawv Tseem Ceeb NtawmT91thiabP91

Cov Lus Txhais thiab Cov Qauv

T91 (T91 Tube) yog cov hlau tubing-qib feem ntau siv rau kev tsim cov raj boiler, superheater thiab reheater, thiab lwm yam khoom tubular. Nws ua raws liASME SA-213cov qauv.

P91 (P91 Yeeb Nkab) yog cov hlau kav dej siv rau kev tsim cov kav dej loj, cov taub hau, thiab lwm yam khoom siv siab. Nws ua raws liASME SA-335cov qauv.

Kev Sib Txawv ntawm Cov Tshuaj Lom Zem

Ob lub hlau sib koom ua ke zoo ib yam tshuaj lom neeg, nrog rau kev hloov pauv me me:

Cov ntsiab lus txhuas: T91 feem ntau muaj cov ntsiab lus txhuas qis dua (≤0.04%), thaum P91 yuav muaj cov theem siab dua me ntsis (≤0.06%)

Cov txheej txheem tsim khoom: T91 feem ntau yog tsim los ua cov yeeb nkab tsis sib txuas, thaum P91 tuaj yeem tsim los ua cov yeeb nkab tsis sib txuas lossis cov yeeb nkab vuam

Cov Khoom Siv Kho Tshuab Sib Txawv

Cov kev cai ntawm lub zog: P91 muaj cov kev cai ntawm lub zog siab dua me ntsis kom haum rau cov kab uas hla loj dua thiab cov phab ntsa tuab dua

Kev cuam tshuam tawv: P91 feem ntau muaj cov kev cai nruj dua rau kev cuam tshuam tawv

Kev kho cua sov: Ob qho tib si xav tau normalizing thiab tempering, tab sis cov kev txwv tshwj xeeb yuav txawv raws li qhov tuab ntawm seem

Cov Cheeb Tsam Thov

Cov Ntawv Thov Tseem Ceeb ntawm T91

Cov raj xa dej superheater thiab cov raj xa dej rov ua kom sov hauv cov boilers fais fab

Cov tshuab raj kub thiab siab

Cov raj xa cua sov sib pauv

Cov khoom siv tubular ua haujlwm ntawm 593-649 ° C

Cov Ntawv Thov Tseem Ceeb ntawmP91

Cov kav dej loj thiab cov kav dej rov ua kom sov hauv cov chaw tsim hluav taws xob

Cov taub hau kub thiab siab, cov taub hau siab thiab cov manifolds

Cov kav dej hauv cov chaw ua haujlwm petrochemical hydrocracking

Cov kav dej ntawm lub zog nuclear

Cov khoom siv siab tuab ua haujlwm ntawm 593-649 ° C

Kev Xav Txog Kev Xaiv

Cov xwm txheej ua haujlwm: Kub, siab, thiab corrosiveness ntawm xov xwm

Hom Cheebtsam: Cov kav dej, cov taub hau, lossis cov khoom sib pauv cua sov tubular

Cov kev cai tsim khoom: Weldability thiab formability

Cov yam tseem ceeb ntawm kev lag luam: Tus nqi pib thiab tus nqi tag nrho ntawm lub neej

Kev ua raws li txoj cai: Yuav tsum ua raws li cov qauv kev lag luam thiab cov cai

Cov Qauv Kev Loj Hlob

Nrog kev nce qib ntawm supercritical thiab ultra-supercritical fais fab tiam thev naus laus zis, ntau yam kev siv ntawm T91 / P91 steels txuas ntxiv nthuav dav. Kev tshawb fawb tam sim no suav nrog:

Txhim kho lub zog nkag mus rau hauv qhov kub thiab txias mus ntev ntxiv

Txhim kho kev ruaj khov mus sij hawm ntev ntawm cov pob qij txha welded

Tsim cov txheej txheem tsim khoom lag luam uas pheej yig dua

Tshawb nrhiav kev siv tau rau hauv cov txheej txheem carbon dioxide

Txawm hais tias T91 thiab P91 muaj cov tshuaj sib xyaw zoo sib xws, lawv muaj qhov sib txawv ntawm cov xwm txheej siv, cov kev cai ua haujlwm, thiab cov qauv tsim khoom. Kev xaiv thiab siv cov ntaub ntawv no kom raug yog qhov tseem ceeb rau kev ua haujlwm kom muaj kev nyab xeeb thiab txuas ntxiv lub neej ua haujlwm ntawm cov khoom siv kub thiab siab. Cov kws ua haujlwm yuav tsum ua cov kev xaiv raws li cov xwm txheej siv tshwj xeeb, cov kev cai tsim qauv, thiab cov qauv kev lag luam.
