1. Dab tsi yog qhov kev siv tseem ceeb ntawm Incoloy 903 seamless thiab welded kav / raj?
Teb:
Incoloy 903 cov kav dej thiab cov raj yog tsim los rau siab - kev ua haujlwm ib puag ncig uas xav tau kev tiv thaiv corrosion thiab lub zog txhua yam. Cov ntawv thov uas muaj xws li:
Cov khoom siv tshuaj ua rau cov kua qaub thiab alkalis
Kev tsim hluav taws xob, suav nrog cov khoom siv hluav taws xob thiab cov boiler tubing
Aerospace thiab siab -kub industrial systems
Roj thiab roj ntau lawm thiab thauj
Nuclear kev lag luam daim ntawv thov uas tsis kam mus rau kev ntxhov siab corrosion cracking yog qhov tseem ceeb
2. Dab tsi ua rau Incoloy 903 cov kav dej thiab cov kav dej zoo dua li cov pa hlau tsis zoo?
Teb:
Cov ntsiab lus siab nickel ua kom muaj kev tiv thaiv corrosion zoo heev hauv oxidizing thiab txo qhov chaw.
Chromium, molybdenum, thiab tooj liab muab kev tiv thaiv rau pitting, crevice corrosion, thiab kev nyuaj siab corrosion cracking.
Ua kom muaj zog tensile thiab tawm los ntawm qhov kub siab (~ 600-650 degree).
Ua tau zoo dua 304 lossis 316 stainless hlau hauv cov kua qaub thiab siab - qhov kub thiab txias, txo cov nqi kho thiab hloov cov nqi.
3. Dab tsi yog cov khoom tseem ceeb ntawm Incoloy 903 cov kav dej thiab cov kav dej?
Teb:
Tensile zog: ~ 700-850 MPa (nyob ntawm phab ntsa thickness thiab ua)
Tawm zog: ~ 300-450 MPa
Zoo heev ductility, cia khoov thiab sib sau tsis muaj cracking
Siab qaug zog tsis kam nyob rau hauv cyclic loading
Khaws txhua yam kev ncaj ncees thiab corrosion kuj ntawm qhov kub thiab txias, haum rau ob qho tib si seamless thiab welded configurations
4. Yuav ua li cas Incoloy 903 cov kav dej thiab cov kav dej yuav tsum tau tsim los yog koom nrog?
Teb:
Vuam: Siv cov nickel{0}}raws li cov hlau; Cov txheej txheem tsim nyog yog yuav tsum tau kom tsis txhob tawg, txawm tias preheating feem ntau tsis tsim nyog.
Bending / Forming: tuaj yeem txias los yog kub khoov, tab sis annealing yuav xav tau tom qab deformation tseem ceeb.
Txiav: Siv cov plasma, laser, lossis dej dav hlau txiav rau cov npoo meej thiab cov cua sov tsawg heev - thaj chaw cuam tshuam.
Seamless vs Welded: Seamless kav yog nyiam rau siab - siab daim ntawv thov, thaum welded kav yog haum rau loj diameters los yog qis dua - kev siv siab.
5. Dab tsi yuav tsum tau xav txog thaum xaiv Incoloy 903 rau ib qhov project?
Teb:
Corrosion ib puag ncig: Zoo tagnrho rau oxidizing, txo, lossis sib xyaw-acid ib puag ncig; tshawb xyuas tshuaj lom neeg.
Kub raug: Haum rau ~ 650 degree; xav txog yog tias muaj qhov kub thiab txias dua.
Mechanical load: Xyuas kom tensile thiab yield zog ua tau raws li qhov yuav tsum tau ua, tshwj xeeb tshaj yog nyob rau hauv siab.
Fabrication thiab installation: Seamless los yog welded xaiv nyob ntawm txoj kab uas hla, phab ntsa thickness, thiab cov nqi txiav txim siab.
Tus nqi -kev ua tau zoo: Txawm hais tias tus nqi pib ntau dua li cov qauv stainless hlau, qhov ntev - lub sij hawm ua haujlwm ntev nyob rau hauv ib puag ncig hnyav txo cov nqi hloov thiab tu.
