Dab tsi yog qhov txiaj ntsig tseem ceeb ntawm kev xaiv Qib 22 Chav Kawm 2 dhau Chav Kawm 1?
Qhov cuam tshuam ntawm tus nqi tseem ceeb ntawm kev xaiv A387 Qib 22 Chav Kawm 2 dhau Chav Kawm 1 suav nrog kev lag luam tawm - tawm ntawm cov nqi pib ntau dua thiab muaj peev xwm txuag tau hauv fabrication thiab post-fabrication processing.
1. Cov khoom siv siab dual Nqi
Mill Processing:Chav Kawm 2 daim hlau tau txais ib qho ntxiv normalizing thiab tempering kub kho ntawm steel zeb, uas ntxiv rau lub hauv paus nqi. Chav kawm 1 daim hlau tsuas yog normalized los yog kev ntxhov siab xwb-tso tseg, ua rau lawv pheej yig dua ib kilogram/pound.
Kev ua lag luam Factors:Chav Kawm 2 feem ntau yog tsim los ntawm cov khoom me me rau cov ntawv thov tshwj xeeb, uas tuaj yeem ua rau lub sijhawm ua haujlwm ntev dua thiab tus nqi them nqi piv rau cov khoom lag luam ntau dua rau Chav Kawm 1.
2. Muaj peev xwm Fabrication nqi txuag
Kev tshem tawm tag nrho rauv PWHT:Rau cov hlab ntsha loj lossis cov hlab ntsha, kev ua haujlwm puv npo-Kev kho cua sov (PWHT) hauv qhov cub loj yog kim heev (lub zog, qhov chaw xauj tsev, kev ua haujlwm). Chav Kawm 2 tuaj yeem tso cai rau PWHT hauv zos nkaus xwb, txo tus nqi loj no.
Simplified Logistics:Kev zam kom tsis txhob thauj lub nkoj loj loj mus rau qhov chaw kho cua sov (lossis nqa cov khoom siv hluav taws xob tuaj rau ntawm -}site) txuag ntawm kev thauj mus los, tuav, thiab teem caij txaus ntshai.
Faster Fabrication Schedule:Kev hla tag nrho lub cub tawg PWHT kauj ruam tuaj yeem ua kom luv luv tag nrho cov sijhawm ua haujlwm, txo cov nqi tsis ncaj thiab ua kom nrawm dua.
3. Ntxiv Fabrication Complexity & Nqi Risks
Strict Welding Controls:Chav Kawm 2's pre-lub xeev tempered xav tau kev tswj hwm nruj dua ntawm preheat, interpass kub, thiab cov txheej txheem vuam kom tiv thaiv kev tawg, uas yuav tsum tau ua haujlwm ntau dua thiab cov txheej txheem tsim nyog.
Risk ntawm dhau-Tempering:Yog tias tseem xav tau PWHT (txawm tias hauv zos), kev tswj qhov kub thiab txias yog qhov tseem ceeb. Tshaj -tempering tuaj yeem ua rau lub hauv paus hlau hauv qab qhov tshwj xeeb, muaj kev pheej hmoo tsis lees paub thiab rov ua haujlwm dua- qhov yuam kev kim heev.
Txwv Kub -Kev Ua Tau Zoo:Yog xav tau kev tsim kub, Chav Kawm 2 daim hlau yuav tsum tau rov ua dua - normalized thiab tempered tom qab ntawd, ntxiv cov kauj ruam uas Chav Kawm 1 yuav dhau mus rau qhov kawg ntawm PWHT. Qhov no negates qee qhov ntawm Class 2 tus nqi kom zoo dua.
4. Kev xav txog lub neej & kev ntseeg siab
Tus nqi pib siab dua, Tsawg Risk:Rau kev pabcuam tseem ceeb (piv txwv li, hydrocrackers), Chav Kawm 2 cov khaub ncaws, zeb-tswj tempering yuav muab cov cuab yeej kwv yees ntau dua hauv cov hlau hauv paus, uas tuaj yeem txo qhov ntev - kev tshuaj xyuas, kev saib xyuas, lossis kev pheej hmoo tsis ua haujlwm.
Tsim Efficiency:Qhov siab dua li - xa lub zog ntawm Chav Kawm 2 tuaj yeem tso cai rau cov phab ntsa nyias nyias hauv qee kis, txuag cov khoom hnyav thiab tus nqi, tab sis qhov no feem ntau yog qhov thib ob rau kev ua raws cai thiab kev tiv thaiv corrosion.
Summary: Tus nqi -Kev txiav txim siab txog txiaj ntsig
Xaiv Chav Kawm 1yog tias qhov project tuaj yeem ua kom haum rau tag nrho lub nkoj PWHT thiab lub hom phiaj kom txo qis cov khoom siv ua ntej. Qhov no yog ib qho zoo rau lub khw-fabricated nkoj uas qhov kev kho cua sov yog tus qauv.
Xaiv Chav Kawm 2thaum tag nrho PWHT yog logistically tsis yooj yim sua los yog txwv tsis pub kim (piv txwv li, teb-fabricated mega-reactors). Tus nqi phaj siab dua yog pauv rau kev txuag nyiaj loj hauv kev zam rau PWHT cov nuj nqis, tuav, thiab ncua sij hawm.
Thaum kawg, qhov kev xaiv yog tus nqi peev (CAPEX) kev ua kom zoo tshaj qhov kev tawm dag zog - ntsuas tus nqi steel rau Chav Kawm 2 tiv thaiv kev tsim cov khoom txuag los ntawm kev kho cua sov yooj yim, nrog rau kev txiav txim siab hnyav nyob ntawm lub nkoj loj, qhov chaw tsim khoom, thiab muaj cov txheej txheem.
1. Qhov kev pheej hmoo tseem ceeb yog dab tsi thaum lub sij hawm Post-Weld Heat Treatment (PWHT) ntawm A387 Qib 22 Chav Kawm 2 cov khoom?
Lo lus nug no tsom mus rau qhov kev sib tw tseem ceeb ntawm kev siv PWHT uas yuav tsum tau ua rau ib qho khoom siv uas twb muaj lawm - tempered, qhov twg tshaj lub sij hawm tshwj xeeb - qhov kub thiab txias tsis tuaj yeem ua rau dhau - tempering thiab poob ntawm cov khoom muaj zog hauv qab qhov tsawg kawg nkaus specification.
2. Vim li cas tus neeg tsim qauv yuav hais kom Class 2 es tsis yog Chav Kawm 1 rau qib 22 reactor?
Lo lus nug no tshawb txog cov laj thawj tseem ceeb ntawm engineering, feem ntau hais txog qhov ua tsis tau zoo ntawm kev ua kom lub cub tawg tag nrho cov kev kho cua sov ntawm lub nkoj loj lossis kev ua tiav tiav, ua rau pre- tempered Class 2 phaj yog qhov tsim nyog xaiv.
3. Charpy cuam tshuam qhov tawv ntawm Chav Kawm 2 piv li cas tom qab vuam thiab PWHT hauv zos?
Cov lus nug no hais txog qhov kev txhawj xeeb tseem ceeb ntawm kev ua haujlwm, tshawb xyuas seb puas muaj cua sov hauv cheeb tsam los ntawm vuam thiab tom qab PWHT tuaj yeem ua rau qhov tsis zoo ntawm cov cua sov- thaj tsam cuam tshuam piv rau lub hauv paus hlau.
4. Tus nqi tseem ceeb thiab kev coj noj coj ua yog dab tsi - lub sij hawm cuam tshuam ntawm kev xaiv Qib 22 Chav Kawm 2 dhau Chav Kawm 1?
Lo lus nug no tshuaj xyuas qhov kev lag luam ua lag luam- tawm dhau qhov kev qhia tshwj xeeb, raws li Chav Kawm 2 phaj feem ntau hais kom tus nqi siab dua thiab tej zaum yuav muaj sij hawm xa khoom ntev dua vim nws cov kauj ruam kho cua sov ntxiv.
Tag nrho cov specification thiab cov ntsiab lus muaj nyob rau ntawm kev thov. Cov ntaub ntawv saum toj no yog muab rau kev taw qhia nkaus xwb. Rau kev tsim tshwj xeeb thov hu rau peb cov neeg ua haujlwm muag khoom.
