Product Description
Thaum cov neeg siv khoom hu rau Jiangsu Cunrui Hlau Khoom Co., Ltd. kom nug txog qhov siab - kub thiab siab - cov ntaub ntawv cov kav dej, ASTM A335 P92 alloy kav feem ntau yog ib qho ntawm cov lus pom zoo siab tshaj -kev xaiv kawg rau peb. Hauv ntau qhov kev ua tau zoo - tshwj xeeb tshaj yog cov uas kub siab tshaj 600℃thiab yuav tsum tau ntev -lub sij hawm tsis kam mus creep thiab oxidation - tsoos Cr-Mo alloy steels (xws li P22, P91) yuav sai sai mus txog lawv cov kev txwv. Feem ntau, P92 dhau los ua kev xaiv nyiaj txiag ntau dua rau cov hom phiaj engineering.
ASTM A335 P92 alloy yeeb nkab yog dab tsi?
ASTM A335 P92 yog ferritic seamless alloy steel yeeb nkab. Nws yog tsim tshwj xeeb rau qhov tseem ceeb heev - kub thiab siab - siab ua hauj lwm tej yam kev mob xws li ultra-supercritical thermal fais fab nroj tsuag los ntawm kev sib xyaw ua ke ntawm cov khoom muaj zog ntxiv zog thiab nag lossis daus. Nws cov ntsiab lus thiab kev ua haujlwm yog raws li hauv qab no:
Chromium (Cr 8.5–9.5%): Muab siab -kub oxidation tsis kam thiab tsis kam mus rau chav oxidation.
Molybdenum (Mo 0.3–0.6%) + Tungsten (W 1.5–2.0%): Compressive solid solution strengthening, ho txhawb qhov siab -kub creep zog
Boron (0.001–0.006%): Cov kab mob ntawm cov boron yog concentrated nyob rau hauv ib thaj tsam ntawm grain, inhibiting creep cavitation thiab ncua lub neej durability.
Tsis zoo li P91, P92 yog raws li 9Cr-1Mo-V-Nb matrix ntawm P91 thiab suav nrog tungsten thiab boron. Raws li peb cov kev paub dhau los, cov neeg siv khoom feem ntau xaiv cov qib no thaum lawv xav tau cov qauv tsim siab dua thiab lub neej ntev dua - nws yog qhov tsim nyog rau cov kav dej tseem ceeb, cov kav dej kub kub, thiab cov kav dej txuas taub hau.
Ntawm Jiangsu Cunrui Hlau Khoom Co., Ltd, peb muab P92 seamless kav uas ua raws li ASTM A335 / ASME SA335 cov qauv, thiab muab kev cai- txiav cov kev pab cuam, txhawb kev ua kom tiav qhov cub tooj traceability thiab meej qhov loj me. Txawm hais tias koj tab tom tsim ultra-supercritical boiler chav nyob ntawm 620 degree, siab - kub thiab siab - cov txheej txheem siab, lossis lwm yam tseem ceeb siab - qhov kub thiab txias Cheebtsam, peb cov P92 alloy kav tuaj yeem muab kev nkag siab ruaj khov thiab ntev - lub sijhawm ua haujlwm ruaj khov.
Koj puas xav tau cov lus hais lossis qauv ntawm daim ntawv pov thawj warranty? Thov hu rau peb kom tau txais kev pabcuam sai thiab ua raws li kev pabcuam.

Kev ua tau zoo ntawm ASTM A335 P92 alloy kav
1.Excellent siab -kub creep zog
P92, los ntawm kev ntxiv tungsten thiab boron rau P91, muaj lub zog tawg tawg nyob rau hauv thaj tsam ntawm 600-625℃uas yog kwv yees li 15-20% siab dua li ntawm P91. Nyob rau hauv tib lub neej tsim, thinner phab ntsa thicknesses siv tau, yog li txo qhov hnyav ntawm cov raj xa dej, thiab txo qhov nyuaj ntawm vuam thiab kev tsim khoom.
2.Excellent kuj rau chav oxidation
Qhov kwv yees li ntawm 9% chromium cov ntsiab lus ua rau P92 tsim cov txheej txheem chromium oxide tiv thaiv nyob rau hauv siab -kub dej vapor ib puag ncig. Nyob rau hauv ob peb ultra-supercritical fais fab nroj tsuag tej yaam num peb muab, qhov saum npoo oxide scale thickness thiab shedding nyiam ntawm P92 kav tom qab ntev -lub sij hawm ua hauj lwm yog ho zoo dua li cov tsoos tsawg-chromium alloy steels.
Stable microstructure thiab mechanical zog
3.P92 ua tiav qhov ruaj khov tempered martensite qauv los ntawm kev ua kom zoo li qub + rov kho cua sov, thiab diffusely precipitates V / Nb carbide nitrides thiab W- nplua nuj Laves theem. Cov qauv no nthuav tawm kev ruaj ntseg microstructural zoo heev thaum lub sij hawm ntev - lub sij hawm siab - qhov kub thiab txias kev pab cuam, zam lub microstructural degradation sai heev pom nyob rau hauv cov tsoos ferritic steels.
4. Txais kev ua thiab vuam cov khoom
Piv rau austenitic stainless hlau, P92, raws li cov cua sov ferritic-cov hlau tsis muaj zog, muaj cov thermal expansion coefficient thiab thermal conductivity uas yog ze rau cov uas feem ntau siv qis- alloy steels, uas yog qhov zoo rau kev txo cov thermal stress. Tom qab vuam, nrog nruj preheating (200-250 degree) thiab post-weld heat treatment (730-770 degree), nws muaj peev xwm tau txais cov pob qij txha nrog cov khoom sib xws. Peb tuaj yeem muab cov txheej txheem vuam pom zoo (WPS) raws li tus lej ntawm lub tshuab hluav taws xob rau kev siv.

Daim ntawv thov teb ntawm ASTM A335 P92 alloy kav
Jiangsu Cunrui Hlau Khoom Co., Ltd.,
peb niaj hnub muab P92 alloy kav rau cov neeg siv khoom hauv qab no:
- Ultra{0}}supercritical thermal zog tsim
Main steam pipeline, siab -kub reheating pipeline, siab -pressure bypass pipeline thiab boiler header txuas yeeb nkab
- Advanced supercritical unit (qib 620 degree)
Raws li cov khoom tseem ceeb rau chav nyob hauv 600-625℃ntau, nws hloov P91 lossis austenitic stainless hlau
- Industrial high -kub txheej txheem pipelines
Qee qhov - kub thiab siab - siab hydrogen - muaj cov kav dej hauv cov nroj tsuag petrochemical
- Kev tshawb fawb txog qib 650℃yav tom ntej
Txhawm rau muab cov ntaub ntawv tshawb fawb yooj yim thiab cov ntaub ntawv thov kev txhawb nqa rau cov koog uas muaj ntau dua
Hauv cov ntawv thov no, cov kev txhawj xeeb tseem ceeb ntawm cov neeg siv khoom feem ntau yog qhov ntev - lub sij hawm siab - kub nkag lub neej thiab oxidation tsis kam, es tsis yog lub sij hawm luv luv - lub zog.
Vim li cas koj thiaj xaiv P92 alloy yeeb nkab tsis yog P91 lossis lwm yam khoom siv?
Peb feem ntau raug nug ib lo lus nug: "Vim li cas ho tsis siv P91 lossis pheej yig dua Cr-Mo steel?"
Raws li kev paub dhau los, thaum muaj xwm txheej hauv qab no tshwm sim, P92 yog qhov kev xaiv zoo dua:
- Tus tsim kub tseem nyob tsis tu ncua saum 590 degree, thiab txawm mus txog ib ncig ntawm 620 degree.
- Ntev - lub neej nkag mus ntev yog qhov tseem ceeb ntawm kev tsim qauv.
- Cov phab ntsa nyias nyias yuav tsum tau ua kom txo tau cov thermal kev nyuab siab thiab qhov hnyav ntawm cov kav dej.
- Hloov kho cov chav tsev tsis muaj raws li P91, tab sis muaj kev txhawj xeeb txog kev hloov lawv nrog cov nqi kim thiab thermally expansive austenitic stainless hlau.
Peb ib zaug tau ntsib qhov xwm txheej uas tus neeg siv khoom pib xaiv P91 tsim, tab sis cov kav xa dej tsis tau raws li qhov yuav tsum tau ua tom qab kev txhim kho parameter. Tom qab hloov mus rau P92, nws muaj peev xwm ua tau raws li qhov xav tau ntawm qhov kub thiab txias siab nrog qhov zoo sib xws ntawm txoj kab uas hla thiab phab ntsa tuab, thiab zam qhov kev ntxhov siab thermal thiab nqi teeb meem tshwm sim los ntawm kev hloov tag nrho cov kab nrog stainless hlau.
Peb qhov kev paub txog kev xa khoom
Ntawm Jiangsu Cunrui Hlau Khoom Co., Ltd., peb tau muab ASTM A335 P92 alloy kav rau ntau yam ultra-supercritical fais fab nroj tsuag tej yaam num nyob rau hauv domestic thiab txawv teb chaws. Peb muaj ntau tshaj 10 xyoo ntawm kev paub hauv cov khoom siv thiab kev koom tes. Peb lub hom phiaj tsis yog tsuas yog xa cov ntaub ntawv uas ua tau raws li ASTM / ASME cov qauv - tab sis kuj tseem pab koj kom haum rau qib uas tsim nyog, kho cua sov lub xeev thiab qhov loj me raws li qhov ntsuas kub ua haujlwm, siab thiab xav tau lub neej ntev.
Raws li peb qhov kev paub dhau los, qhov ntev - kev ua tiav ntawm P92 qhov project yog nyob ntawm peb yam tseem ceeb:
