T91thiabP91yog ob lub hlau stainless hlau martensitic uas siv dav dav, kub thiab muaj zog, uas tau los ntawm 9Cr-1Mo-V alloy system. Lawv raug faib ua pawg sib txawv vim muaj kev hloov pauv ntawm cov qauv tsim khoom thiab cov qauv khoom, tab sis ob qho tib si ua lub luag haujlwm tseem ceeb hauv kev lag luam zog thiab tshuaj lom neeg. Hauv qab no yog kev tshuaj xyuas ntxaws ntxaws ntawm lawv qhov sib txawv thiab daim ntawv thov.

1. Qhov Txawv Tseem Ceeb Ntawm T91 thiab P91

•Daim Ntawv Khoom thiab Cov Qauv:

T91: Faib ua "Tube" lossis "Tubing" raws li ASME (American Society of Mechanical Engineers) cov qauv. Nws feem ntau yog siv rau cov raj boiler, cov raj superheater, thiab cov raj reheater.

P91: Faib ua "Yeeb nkab" raws li cov qauv ASME. Nws feem ntau yog siv rau hauv cov kav dej loj, cov kav dej siab loj, thiab cov taub hau.

•Cov Kev Cai Tsim Khoom:

T91 xav tau qhov tseeb ntawm qhov ntev, qhov zoo ntawm qhov chaw, thiab kev ua haujlwm khoov kom haum rau kev npaj cov raj boiler nyuaj.

P91 tsom mus rau qhov muaj peev xwm ua kom lub zog siab ntawm phab ntsa tuab thiab weldability, ua rau nws haum rau cov khoom loj.

•Kev Ua Tau Zoo:

Txawm hais tias ob qho tib si alloys muaj cov tshuaj sib xws, lawv cov qauv me me thiab cov txheej txheem kho cua sov sib txawv me ntsis. T91 muab qhov tseem ceeb rau qhov kub siab thiab kev tiv thaiv kev xeb ntawm cov pa roj flue, thaum P91 hais txog kev tawv thiab kev ruaj khov mus sij hawm ntev.

2. Cov Ntawv Thov

•Kev Lag Luam Tsim Hluav Taws Xob:

T91 feem ntau yog siv rau hauv cov khoom kub siab ntawm supercritical thiab ultra-supercritical fais fab nroj tsuag boilers, xws li superheater thiab reheater raj, muaj peev xwm ua haujlwm ntev ntawm qhov kub txog li 620°C.

P91 siv rau hauv cov kav dej loj, cov taub hau, thiab cov qhov cua sov siab, muab lub peev xwm zoo heev rau cov kab ke sib kis tseem ceeb hauv cov chaw tsim hluav taws xob.

•Kev Lag Luam Petrochemical:

Ob qho tib si alloys yog siv rau hauv cov reactors kub thiab siab, cov khoom hloov pauv cua sov, thiab cov chav tawg, qhia txog kev tiv thaiv rau cov chaw corrosive xws li hydrogen sulfide.

•Lwm Cov Kev Lag Luam:

Cov no suav nrog cov tshuab pabcuam hauv cov chaw tsim hluav taws xob nuclear thiab cov khoom siv kho cua sov kub siab uas xav tau kev tiv taus cua sov thiab siab.

3. Kev Xav Txog Kev Xaiv

Qhov kev xaiv ntawm T91 thiab P91 nyob ntawm cov xwm txheej ua haujlwm tshwj xeeb: T91 yog qhov zoo dua rau cov kav dej me me, nyias-phab ntsa uas xav tau kev khoov, thaum P91 yog qhov tsim nyog dua rau cov kav dej loj, tuab-phab ntsa ncaj lossis cov khoom siv. Ob qho tib si alloys xav tau kev tswj hwm nruj rau kev vuam thiab cov txheej txheem kho cua sov kom ua tiav lawv cov txiaj ntsig kev ua haujlwm kub siab.
