Rau cov tshuab hluav taws xob uas kub thiab siab, kev xaiv cov khoom siv tsis yog tsuas yog xaiv cov yeeb nkab hlau uas muaj zog siab xwb.ASTM A335 P91 seamless hlau yeeb nkabtau teev tseg dav dav rau kev pabcuam kub siab vim nws txoj kev tsim alloy thiab kev kho cua sov muaj feem cuam tshuam nrog kev ua haujlwm ntev.
Rau cov neeg yuav khoom, txawm li cas los xij, qhov teeb meem tiag tiag feem ntau tsis nrhiav tus neeg muab khoom P91 yeeb nkab. Nws yog xyuas kom meej tiasqib, kev kho cua sov, kev tshuaj xyuas, kev sau ntawv thiab kev taug qabtxhua yam phim cov lus qhia ntawm qhov project.
Vim li casASTM A335 P91 Siv rau hauv Cov Tshuab Fais Fab Kub Siab?
ASTM A335 P91yog ib hom yeeb nkab ferritic alloy-steel uas tsis muaj seamless uas tsim los rau kev pabcuam kub siab. ASTM txheeb xyuas A335 ua ib qho kev qhia tshwj xeeb uas npog cov yeeb nkab ferritic alloy-steel uas tsis muaj seamless rau kev siv kub siab, nrog rau cov kev cai uas suav nrog cov tshuaj lom neeg sib xyaw, cov khoom siv kho tshuab, qhov nyuaj thiab kev sim.
P91 muaj kwv yees li 8–9.5% chromium thiab 0.85–1.05% molybdenum, ua ke nrog cov khoom ntxiv uas tswj tau xws li vanadium, niobium thiab nitrogen. Cov qauv hlau no txhawb nqa lub zog thiab kev tiv taus kev nkag mus rau hauv cov xwm txheej uas xav tau kev pabcuam hnyav.
Cov ntawv thov ib txwm muaj rauP91 hlau yeeb nkabsuav nrog:
· Lub chaw fais fab loj thiab cov tshuab ua kom sov kub dua
· Cov kav dej boiler thiab superheater
Cov kav dej kub siab
· Cov chaw tsim hluav taws xob fossil thiab cov chaw tsim hluav taws xob sib xyaw ua ke
· Cov kav dej kub siab thiab cov khoom siv cuam tshuam
Yuav tsum xaiv qib uas tsim nyog raws li qhov kub thiab txias, siab, cov xwm txheej kev pabcuam thiab cov lej engineering uas siv tau es tsis yog xaiv los ntawm lub npe qib xwb.
P91 vs P22Vim li cas cov neeg yuav khoom thiaj li tsis tuaj yeem kho lawv zoo li cov khoom hloov pauv yooj yim?
P91 piv rau P22yog ib lo lus nug nquag hauv kev yuav khoom siv hluav taws xob.
P22 yog cov hlau Cr-Mo uas muaj cov hlau tsawg dua, thaum P91 muaj cov ntsiab lus chromium ntau dua thiab muaj cov qauv hlau nyuaj dua. Yog li ntawd, ob qib no muaj cov yam ntxwv ntawm cov khoom siv thiab cov ntawv thov haujlwm sib txawv.
Rau kev yuav khoom, qhov tseem ceeb tshaj plaws yog:
P91 yuav tsum tsis txhob hloov los ntawm P22—lossis P22 los ntawm P91—vim tias qhov loj me zoo sib xws.
Qhov kev sib piv kom raug yuav tsum muaj xws li:
· Qhov kub thiab siab ntawm kev tsim qauv
· Cov kev xav tau ntawm kev nkag mus thiab lub zog ntev
· Cov tshuaj lom neeg muaj pes tsawg leeg
· Kev kho cua sov
Cov khoom siv kho tshuab
· Cov kev cai ntawm kev vuam
· Cov kev cai ntawm PWHT
· Cov kev cai NDE thiab kev tshuaj xyuas
· Cov cai tsim qauv thiab kev tsim kho uas siv tau
Qhov no tseem ceeb heev thaum yuav cov khoom siv hloov rau lub tshuab fais fab uas twb muaj lawm.
P91 vs T91: Kev sib raug zoo yog dab tsi?
Lwm qhov kev tshawb nrhiav ntau zaus yogP91 vs T91.
Ob qib no muaj feem cuam tshuam nrog kev sib xyaw ua ke, tab sis lawv yog cov khoom ASTM sib txawv.
ASTM A335 P91yog teev tseg rau cov yeeb nkab ferritic alloy-steel seamless, thaumASTM A213 T91yog them rau hauv qab cov lus qhia rau seamless ferritic thiab austenitic alloy-steel boiler, superheater thiab heat-exchanger tubes.
Yog li ntawd, P91 thiab T91 yuav tsum tsis txhob raug suav hais tias yog cov khoom sib pauv tau vim tias lawv cov npe tshuaj lom neeg zoo sib xws.
Yuav tsum tau kuaj xyuas cov qauv khoom, qhov loj me, cov kev cai tsim khoom, daim ntawv thov thiab cov lus qhia tshwj xeeb ntawm qhov project ua ntej hloov pauv.
Vim Li Cas Kev Kho Mob Kub Thiaj Tseem Ceeb Rau P91
RauP91 seamless yeeb nkab hlau, kev kho cua sov tsis yog qhov tseem ceeb ntawm kev tsim khoom thib ob. Nws yog ib feem tseem ceeb ntawm kev ua tiav cov khoom siv uas xav tau.
Yog li ntawd, cov lus qhia txog kev yuav khoom P91 yuav tsum qhia meej txog qhov xav tau:
· Kev kho cua sov
Cov ntaub ntawv kho cua sov
· Cov txiaj ntsig ntawm kev sim tshuab
· Cov txiaj ntsig ntawm qhov nyuaj
· Cov tshuaj lom neeg muaj pes tsawg leeg
· Kev txheeb xyuas qhov kub/qhov ntau
· Cov qauv txheem siv tau
ASTM A335 xav kom cov khoom siv ua raws li cov kev cai tshuaj lom neeg, tensile thiab hardness, thiab tus qauv kuj suav nrog cov kev cai kuaj hydrostatic thiab nondestructive.
Vim li no, cov neeg yuav khoom yuav tsum tsis txhob yuav P91 tsuas yog los ntawm cov lus hais tias "ASTM A335 P91." Cov lus qhia txog kev ua haujlwm tiav yog qhov tseem ceeb.
NDE thiab Kev Tshuaj Xyuas: Cov Neeg Yuav Khoom Yuav Tsum Tshawb Xyuas Dab Tsi?
Ib qho txhim khu kev qhaKev tshuaj xyuas cov yeeb nkab P91qhov kev pab cuam yuav tsum mus dhau qhov kev tshuaj xyuas pom thiab kev ntsuas qhov ntev.
Nyob ntawm seb qhov project specification thiab cov kev cai ntxiv uas siv tau, cov neeg yuav khoom yuav tsum tau xyuas kom meej:
Kev tshuaj xyuas tshuaj lom neeg
· Kev ntsuam xyuas lub zog
· Kev ntsuam xyuas qhov nyuaj
· Kev tshuaj xyuas qhov ntev
· Kev kuaj hydrostatic
· Cov kev cai ntawm NDE
Cov ntaub ntawv kho cua sov
· Qhov chaw nto
· Kev txheeb xyuas thiab cim cov khoom siv
· Kev tshuaj xyuas los ntawm lwm tus, thaum xav tau
ASTM A335 qhia meej txog kev kuaj hydrostatic thiab kev kuaj tsis puas tsuaj rau cov yeeb nkab uas muab los ntawm tus qauv. Cov kev cai tshuaj xyuas ntxiv kuj tseem yuav raug teev tseg hauv daim ntawv yuav khoom.
Yog li ntawd, txoj kev NDE tseeb thiab cov qauv lees txais yuav tsum tau lees paub raws li tsab ntawv siv tau ntawm tus qauv thiab cov lus qhia ntawm qhov project.
MTC thiab Kev Taug Qab: Cov Ntaub Ntawv Tseem Ceeb Ib Yam Li Cov Yeeb Nkab
Rau cov phiaj xwm fais fab,P91 MTCthiabkev taug qab cov ntaub ntawvyog cov kev txiav txim siab tseem ceeb rau kev yuav khoom.
Ib pob khoom siv kom zoo yuav tsum txuas nrog:
Tus lej cua sov → Yeeb nkab → Kev kho cua sov → Cov txiaj ntsig sim → MTC → Cov ntaub ntawv tshuaj xyuas
Cov neeg yuav khoom yuav tsum xyuas seb puas muaj cov khoom seemDaim Ntawv Pov Thawj Xeem Khoom Siv (MTC)qhia meej txog qib khoom siv, tus lej kub, cov tshuaj lom neeg sib xyaw, cov khoom siv kho tshuab, cov ntaub ntawv kho cua sov thiab cov txiaj ntsig xeem xav tau.
Rau cov haujlwm EPC loj, teeb meem kev taug qab tuaj yeem ua rau muaj kev ncua sijhawm thaum pom zoo cov khoom siv, kev tsim khoom lossis kev tshuaj xyuas cov ntaub ntawv kawg - txawm tias thaum lub yeeb nkab nws tus kheej zoo li siv tau.
Yuav tsum tau lees paub ua ntej kev txiav txim siab txog kev vuam thiab PWHT
P91 feem ntau siv rau hauv cov kav dej kub siab welded, yog li ntawdP91 vuamthiabPWHTyuav tsum tau xav txog thaum lub sijhawm yuav khoom es tsis yog tom qab cov yeeb nkab tuaj txog.
Cov txheej txheem vuam, kev ua kom sov ua ntej, kev tswj hwm kev hla, kev kho cua sov tom qab vuam thiab cov kev cai tshuaj xyuas cuam tshuam yuav tsum tau teeb tsa raws li cov lus qhia ntawm qhov project, kev tsim nyog ntawm cov txheej txheem vuam thiab cov cai tswj hwm.
Yog li ntawd, tus neeg yuav khoom yuav tsum muab cov kev cai tsim nyog rau tus neeg muag khoom ua ntej tsim khoom thaum twg ua tau.
Qhov no pab xyuas kom meej tias cov khoom siv thiab cov ntaub ntawv muab los tuaj yeem txhawb nqa cov txheej txheem tsim khoom thiab kev teeb tsa tom qab.
Vim li cas P91 Kev Yuav Khoom Yuav Tsum Tsis Yog Raws Li Tus Nqi Xwb
Tus nqi qis tshaj plaws tsis tas yuav yog tus nqi qis tshaj plaws ntawm qhov project.
RauP91 hlau yeeb nkab, kev pheej hmoo ntawm kev yuav khoom yuav suav nrog:
Qib lossis cov lus qhia tsis raug
Cov ntaub ntawv kho cua sov tsis tiav
· Tsis muaj kev taug qab
· MTC tsis ua raws li txoj cai
Cov ntaub ntawv NDE tsis txaus
· Kev tshuaj xyuas los ntawm lwm tus neeg qeeb
· Muaj teeb meem thaum cov neeg siv khoom pom zoo cov khoom siv
· Teeb meem sau ntawv thaum lub sijhawm xa daim ntawv thov haujlwm
Rau cov haujlwm fais fab thiab kev lag luam uas muaj nqis heev, cov teeb meem no tuaj yeem tsim cov nqi ntau dua li qhov sib txawv ntawm tus nqi yeeb nkab thaum pib.
Ib txoj kev yuav khoom zoo dua yog kev soj ntsuamKev ua raws li cov khoom siv + kev tshuaj xyuas + cov ntaub ntawv pov thawj + kev taug qab + kev muaj peev xwm xa khoomua ke.
