Cov kev hloov pauv cuam tshuam nrog cov khoom siv
● Ua kom cov kev xav tau ntawm cov khoom siv qib. Piv txwv li, valve qia F6a-II tsub kom qhov yuav tsum tau rau cov tshuaj muaj pes tsawg leeg ntawm cov ntaub ntawv rau siab-bearing qhov chaw thiab siab-tswj qhov chaw.
● Rau kev tswj cov sulfur thiab phosphorus cov ntsiab lus ntawm cov khoom siv vuam kawg, cov kev xav tau siab dua tau muab tso rau pem hauv ntej:
→● Cov ntsiab lus sulfur tsis pub tshaj 0.020%;
→● Cov ntsiab lus sulfur yuav tsum tsis pub tshaj {{0}}.020% thiab cov ntsiab lus phosphorus yuav tsum tsis pub tshaj 0.025%.
Cov qub version yog 0.035%.
● Toughness xeem yuav tsum tau. Rau duplex stainless hlau kom muaj kev cuam tshuam toughness yuav tsum:
→ Tus nqi nruab nrab ntawm peb tus qauv: yam tsawg kawg nkaus 45J;
→ Tus nqi tus nqi tsis tsawg dua 35J;
→● Qhov ntsuas kub yuav tsum yog -46 degree .
● Compatibility ntawm cov khoom siv roj hmab
Rau cov li qub ntau dua lossis sib npaug rau Chav Kawm 600, cov ntaub ntawv pov thawj tawg yuav tsum raug xaiv raws li kev ua haujlwm gaseous nrog kev txo qis sai.
● Cov khoom siv rau cov kua qaub rau cov khoom siv siab thiab kev tswj lub siab yuav tsum raug xaiv raws li NACE MR0175 lossis raws li MR 0103, thiab tus neeg yuav khoom yuav tsum qhia tus qauv siv (uas txawv ntawm tus qauv qub tus qauv specification kom tau raws li ISO 15156)
● Tshiab: Kev ntsuas Tensile raug coj mus kuaj (TC) tom qab kev kho cua sov kawg. Chav ntsuas kub tensile yog raws li ASTM A370 lossis ISO 6892-1. Tsawg kawg yog ib qho kev sim tensile yog tsim thiab lub zog tawm los yog txiav txim siab siv 0.2% residual deformation.
Forging cov ntaub ntawv tsis tau hais tias yuav tsum tau grain loj

Cov kev hloov pauv cuam tshuam nrog vuam
1, cov khoom siv vuam yuav tsum ua raws li AWS thiab cov chaw tsim khoom tshwj xeeb, xaiv cov khoom siv hluav taws xob tsawg (xws li cov hlau, flux) thiab raws li cov chaw tsim khoom tau pom zoo rau kev khaws cia thiab siv, txhawm rau tswj cov khoom siv hydrogen tsawg. ntawm cov khoom.
2. Qhov yuav tsum tau ua rau saum npoo los yog cladding vuam ntawm cemented carbide, cov tshuaj muaj pes tsawg leeg ntawm cov thickness ntawm cov surfacing los yog cladding yuav tsum ua raws li cov hauv qab no:
Chav Kawm Fe10: Cov ntsiab lus hlau loj txog li 10%;
Chav Kawm Fe 5: cov ntsiab lus hlau loj txog li 5% thaum tus neeg yuav khoom qhia
Surfacing thickness yuav tsum: yam tsawg kawg nkaus thickness ntawm 3.0mm, yuav tsum tau nto ob txheej;
3. Kev kho qhov tsis xws luag hauv forgings lossis daim hlau tsis raug tso cai, tshwj tsis yog tias pom zoo.
Weld patching ntawm castings tuaj yeem siv los kho qhov ua yuam kev. Tom qab kho yuav tsum ua raws li tus txheej txheem tom qab vuam cua sov kho PMHT
4, tshiab muab tub lim vuam yuav tsum, muab tub lim vuam kom ua raws li 5.1 tsim cov cai, nrog rau cov phab ntsa thickness xav txog. Patch welding yuav tsum ua raws li tus qauv kev kho cua sov tom qab PMHT.

kev tswj xyuas qhov kev hloov pauv zoo
1, Kev ntsuas ntsuas ntsuas
Kev ntsuas siab yuav tsum tau ua nyob nruab nrab ntawm 20% thiab 80% ntawm tag nrho cov ntsuas ntawm manometer, qhov qub version yog: 25% txog 75%
Cov cuab yeej kaw lub siab tshiab tsis yog 8.2.3.1, piv txwv li: lub kaw lus siab
2. Calibration voj voog
Ntxiv qhov tsim ntawm lub voj voog calibration ntawm kev ntsuas ntsuas
Lub voj voog calibration yog qhov siab tshaj plaws ntawm peb lub hlis:
Lub sij hawm calibration yuav luv luv los yog lengthened raws li cov kev cai npaj los ntawm cov chaw tsim tshuaj paus nyob rau hauv kev hloov ntawm lub sij hawm thiab kev ntsuam xyuas ntawm lub calibration keeb kwm, thiab lub siab tshaj plaws calibration lub sij hawm yuav tsum tsis txhob ntau tshaj ib xyoos.
3. Cov khoom siv kho cua sov calibration
Ua raws li ntu 6.1
Cov cuab yeej kho cua sov tsawg kawg ib xyoos ib zaug (hauv 12 lub hlis) calibration thiab ntsuas
4, raws li ASNT SNT-TC-1A lossis ISO9712 ua lub hauv paus rau kev ntsuas, tsis tau lees paub EN473 tus qauv
5, vuam inspector
Rau kev soj ntsuam pom ntawm cov neeg ua haujlwm vuam ua haujlwm raws li ib qho ntawm cov kev ntsuam xyuas thiab kev pom zoo hauv qab no:
AWS QC1 los yog sib npaug certified welding inspectors;
AWS QC1 los yog sib npaug certified senior welding inspector;
AWS QC1 los yog sib npaug Certified Relevant Welding Inspector;
Cov chaw tsim khoom yuav tsum muaj daim ntawv qhia kev cob qhia rau cov kws tshuaj ntsuam xyuas vuam. Cov qub version tsis tsom rau QC1
6, castings pom kev soj ntsuam
Tsis tsuas yog qhia meej raws li MSS SP-55 kev tshuaj xyuas, thiab muab cov lus qhia lees paub:
Hom 1 tsis tuaj yeem lees txais
Hom 2 - 12, tsuas yog A thiab B tuaj yeem tau txais
