Daim ntawv thov teb ntawm A387 Qib 22 Chav Kawm 2 yog dab tsi?
A387 Qib 22 Chav Kawm 2yog tsim los tshwj xeeb rau qhov tseem ceeb, siab - kub, thiab siab - siab welded siab hlab ntsha hauv kev lag luam uas nws ua ntej - tempered, siab - lub zog muaj zog muaj qhov sib txawv fabrication thiab kev ua tau zoo. Nws daim ntawv thov teb tau txhais los ntawm cov kev pabcuam hnyav uas qis dua -qib alloys tsis txaus.
Thawj Daim Ntawv Thov Fields:
1. Petroleum Refining & Hydroprocessing
Hydrocracker Reactors: Daim ntawv thov iconic tshaj plaws. Cov hlab ntsha no ua haujlwm nyob rau hauv huab cua hydrogen ib nrab siab thiab kub siab (feem ntau> 425℃/ 800℃F). Qib 22 Chav Kawm 2 qhov kev tiv thaiv zoo tshaj rau hydrogen nres (ib API 941 Nelson Curve) thiab siab - qhov kub thiab txias yog qhov tseem ceeb.
Hydrotreating & Hydrodesulfurization (HDS) Reactors: Rau tshem tawm cov sulfur thiab lwm yam impurities nyob rau hauv siab - siab hydrogen.
Cov sib cais tseem ceeb & siab -Tsev Dej Kub hauv cov txheej txheem refinery ntws.
2. Kev tsim hluav taws xob
Siab -Cov Cheebtsam Siab Boiler: Xws li lub nruas nruas, lub taub hau, thiab cov khoom siv hluav taws xob nyob hauv cov pob txha- cov roj hluav taws xob hluav taws xob thiab cov tshuab hluav taws xob rov qab cua sov (HRSGs), qhov kub siab tshaj qhov muaj peev xwm ntawm Qib 11 steels.
Advanced Power Cycles: Rau cov khoom siv hauv ultrasupercritical (USC) cov nroj tsuag xav tau kev txhim kho creep zog.
3. Petrochemical & Chemical processing
Reactors hauv Methanol, Ammonia, thiab Ethylene Production uas ua haujlwm nyob rau hauv siab -kub hydrogen ib puag ncig.
Lub Hwj Hwj Hwj Hwj Hwj Hwj Hwj Hwj Hwj Hwj Hwj Hwj Hwj Hwj Hwj Hwj Hwj Hwj Hwj Hwj Hwj Hwj Hwj Hwj Hwj Hwj Hwj Hwj Hwj Hwj Hwj Hwj Hwj Hwj Hnyav yog qhov tsim nyog rau oxidation thiab corrosion kuj ntawm 2.25Cr-1Mo.
4. Roj & Roj (Upstream & Midstream)
Siab -Ntsuj roj kho cov nkoj thiab cov khoom siv hauv cov kev pabcuam qaub hnyav (thaum ua ke nrog cov cladding kom zoo lossis vuam overlays).
Vim li cas Chav Kawm 2 tau teev nyob rau hauv cov teb no:
Kev xaiv ntawm Chav Kawm 2 dhau Chav Kawm 1 yog tsav los ntawm kev tsim tsim nyog hauv cov ntawv thov no:
Loj lossis Field-Vessels tsim: Reactors feem ntau loj dhau rau cov chaw ua kom sov, ua kom tag nrho lub nkoj Post-Weld Heat Treatment (PWHT) tsis siv tau lossis tsis tuaj yeem kim. Chav kawm 2 tuaj txog ua ntej- tempered, tso cai rau PWHT hauv zos tsuas yog ntawm welds.
Complex Internals: Cov nkoj ntim nrog cov tais catalyst lossis cov khoom siv sab hauv uas tsis tuaj yeem tiv taus lub voj voog tag nrho. Chav Kawm 2 txo qis kev kho cua sov lub nra tom qab kev teeb tsa sab hauv.
Kho & Revamp Projects: Hloov cov seem los yog lub nozzles yuav tsum ua kom haum cov tempered microstructure uas twb muaj lawm thiab muaj zog dua nyob rau hauv - cov cuab yeej siv yam tsis tas yuav tsum tau tag nrho re- kho cua sov.
Teem caij -Driven Projects: Cov kev kho ua ntej- kho tau tuaj yeem ua kom luv luv ntawm cov txheej txheem tsim los ntawm kev tshem tawm lub cub tawg ntev ntev PWHT kauj ruam.
Tseem Ceeb Limitation & Design Note:
Thaum Chav Kawm 2 raug xaiv rau nws "npaj-rau- siv" lub zog, nws daim ntawv thov tsis yog rau qhov hnyav tshaj plaws los yog qaug zog- cov kev pabcuam tsav tsheb yam tsis muaj kev tshuaj xyuas nruj. Qhov yuav tsum tau ua hauv PWHT tom qab vuam tsim cov txheej txheem kev ntxhov siab uas yuav tsum tau ua tib zoo xav txog kev tsim tawm tsam creep- qaug zog puas tsuaj hauv cov kev pabcuam huab cua.
Hauv cov ntsiab lus, A387 Qib 22 Chav Kawm 2 yog cov khoom ntawm kev xaiv rau qhov xav tau tshaj plaws siab - kub / siab- siab hydrogen pabcuam nkoj, tshwj xeeb tshaj yog thaum engineering txwv txwv tsis pub zaum kawg, kev kho cua sov tag nrho ntawm cov khoom ua tiav. Nws siv yog ib qho kev sib haum xeeb uas ua rau qhov tseem ceeb ntawm kev tsim cov khoom tsim tau thaum tswj hwm qhov tseem ceeb siab -kev ua haujlwm kub ntawm 2.25Cr-1Mo alloy steel.
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.
