1. Cov Qauv Txheej Txheem Qhia thiab Txheej Txheem Kev Txhais
ASTM A691 yog qhov kev ntsuas kub siab thiab cov roj ntsha siab tsim los ntawm cov neeg Asmeskas hlau thiab cov ntaub ntawv chromium thiab chromal-molybdenum alien hlau rusion vuam (EFW) txheej txheem.
EFW (electroction vuam) siv hluav taws xob arc kom yaj cov khoom los ua tus weld. Tsis muaj qhov siab ntxiv thaum lub sijhawm tag nrho. Sab hauv phab ntsa ntawm Weld yog du thiab muaj kev sib khi zoo. Nws yog qhov haum rau cov xwm txheej siab tshaj plaws (ua haujlwm siab 0.6-1.6MPA).
2. Cov khoom siv sib xyaw thiab qib kawm
Hom Tshuaj Alloy: npog cov hlau roj rau 9% chromium-molybdenum alloy steel (0.45% -1.5%), vanadium, thiab niobium.
Qib Cim: Muaj npe "{691+ chromium cov ntsiab lus +), thiab cov ntawv yuav tsum tau kho cov cua sov thiab tshuaj xyuas cov kev xav tau.
3. Cov thev naus laus zis tseem ceeb ntawm kev tsim cov txheej txheem
Ua raws li cov thev naus laus zis: jcoe (khoov dabtsi yog khoov) lossis uoe (compression moulding) yog siv, thiab kev sib tw raug yog tswj tau ntawm ± 0.5mm.
Vuam thiab tom qab-ua: Muab dej rau ntawm cov vuam arc vuam (HFW) los yog HFW) los xyuas kom meej ob sab sib txawv ntawm Welds.
Tom qab vuam, li qub (920℃± 10 degree) + qib siab) yuav tsum tau ua kom ua kom zoo rau kev ua kom pom kev kub lub ntsej muag thiab tshem tawm cov kev ntxhov siab.
Kev Soj Ntsuam Zoo: 100% Kev Ntsuas Zoo (RT) thiab Ultrasonic Kev Ntsuas (U), tej yam sib raug zoo yuav tsum ua kom tiav ntau dua lossis sib npaug ntawm 54J ntawm -20 degree.
Kev ntsuam xyuas dej siab txog 1.5 zaug tsim kev tsim siab, thiab lub siab yog tswj hwm rau ntau dua lossis sib npaug rau 30 feeb.
Daim ntawv thov tseem ceeb
1. Zog Thiab Fais Fab Teb
SuperCritical Boilelines: Kev Kub Siab Hluav Taws Xob Cov Hluav Taws Xob Uas Muaj Khoom Kub Ntau dua li 550 Qib (xws li Lub Cim Hluav Taws Xob Ntau dua lossis sib npaug rau 150 hli).
Nuclear zog cog cov txheej txheem: cua txias dej sab nraum lub kob nuclear, uas yuav tsum ua kom tau raws li cov kev cai ntawm -40℃cov kev cuam tshuam nyuaj.
2. Petrochemical Teb
Hydrogenation Reactor Pipelines: tiv thaiv cov roj thiab roj ib nrab ntawm lossis sib npaug rau 0.01mpa, thiab corrosion tus nqi tsawg li 0.03mm / xyoo.
Catalytic cracking unit: high-kub (tsawg dua los yog sib npaug zos rau 650 degree) Kev Ntsuas Siab) Kev Tsim Kho Siab Txuas Pipelines.
3. Kev lag luam tsheb thauj neeg
Cov tsheb sib sau siab thiab cov tsheb thauj mus los: ntev-cov roj tsheb thauj mus los ntev thiab roj tsheb thauj mus los ntau dua los yog sib luag rau 15mpa.
Cov ntsiab lus tseem ceeb rau kev xaiv ua haujlwm thiab kev lees txais
Qeb Kev Ua:
Rau cov kev mob kub tsawg (hauv qab -29 degree), xws li A691 cm-65 CL22) yog qhov nyiam ua kom muaj kev cuam tshuam nyuaj.
Rau cov xwm txheej kub siab (> 550 degree), siab chromium alloys (xws li 5cr / 9cr) yuav tsum raug xaiv.
Cov ntaub ntawv pov thawj:
Nws yog ib qho tsim nyog los thov Daim Ntawv Qhia Kev Kho Mob Kub (noraling + Tempering Temper
Vuam ua raws cai:
Lub chaw tsim khoom yuav tsum tau tuav cov khoom lag luam tsim khoom tshwj xeeb, thiab cov chaw ntsuas chaw ib puag ncig (ntsuas kub, voltage) yuav tsum tau sau cia thiab archived.
