Lub cev thiab tshuaj lom neeg ntawm inconel718 alloy raj
1. cov cev nqaij daim tawv
Quav: Lub ntom ntawm inconel 718 alloy raj yog li 8 {} {{{{{4} {{4 3} {{3} {{4 3} {{4 3} {{4 3} {{4 3} {} Kev ua tau zoo thaum ntsib kev xav tau kev ua tau zoo xws li lub zog.
Melting taw tes: nws melting point ntau yog kwv yees {}} qhov siab tshaj plaws ntawm huab cua thiab deforming cov kev kub ntxhov hauv kev lag luam petrochemical ....
Thermal nthuav tawm coefficient: hauv qhov kub thiab txias linear kev nthuav dav txog li ntawm 13 {{{{}} × 10 × 10⁻⁶ / degree. Qhov tsim nyog thermal expansion coefficient ua rau lub raj loj ua rau muaj kev ntxhov siab thiab muaj zog, yog li ua kom muaj kev ntseeg siab ntau dhau los thiab kev ntseeg tau ntawm cov khoom siv.
Thermal conductivity: ntawm 20 degree, lub thermal conductivity ntawm inconel yuav nce ntxiv} {{{{{{{{{{{{{{{{}}} {{{{{{} {{{{{{{10} Qhov tseem ceeb ntawm cov thermal tsawg txhais tau hais tias lub raj alloy muaj qee qhov kev ua haujlwm thermal. Nyob rau qee lub sijhawm uas yuav tsum tau hloov cua sov, yuav tsum tau tswj hwm, xws li cov raj xa hluav taws xob ntawm cov cua sov kub, nws tuaj yeem txo cov cua sov thiab txhim kho kev siv hluav taws xob.
Conductivity: kev ua haujlwm ntawm inconel 718 Alloy Tube yog tsawg} Qhov no yuav tsum muaj hluav taws xob hluav taws xob tiv thaiv hluav taws xob thiab ua kom muaj kev ua haujlwm zoo ntawm cov Cov khoom . tib lub sijhawm, tsis muaj kev cuam tshuam tau hais tias nws yuav tsum tau siv cov kev siv hluav taws xob, nws yuav tsum tau xaiv qhov kev xav tau tshwj xeeb.
2.} tshuaj lom neeg
Anti-oxidation kev ua haujlwm: inconel 718 alloy tubrog muaj kev ua yeeb yam zoo tshaj plaws hauv cov huab cua sov { oxidation {6. Raws li qhov kub thiab lub ntsej muag zoo li no, yog li cov yeeb yaj kiab oxide { Thaum siv sijhawm ntev nyob rau hauv ib puag ncig kub nyob hauv qis dua 800 degree, thiab yuav tsis ua teeb meem xws li thinning oxidation .
Corrosion Kuj:
General corrosion: hauv cov dej muaj txiaj ntsig zoo, cov txiaj ntsig 718} Cov kab mob alloy, cov roj ntsha ua kom zoo nyob rau hauv cov chaw ib txwm muaj nyob hauv cov chaw ib puag ncig no. Piv txwv, Tom qab raug rau cov neeg muaj chaw muaj kev lag luam hauv ib puag ncig ntau xyoo, kev kawm yeeb nkab ntawm alloy yog heev me ntsis thiab tsis zoo cuam tshuam rau nws li qub.
Dej hiav txwv corrosion: Rau cov corrosive media xws li sorrosion ntawm corroside {}} Cov txiv neej ua hauj lwm tseem ceeb ntxiv rau cov alloy lub zog tiv taus chloride ion pitting thiab Crevice corrosion. Nyob rau hauv kev ua haujlwm ntawm cov khoom siv dej hiav txwv uas muaj peev xwm tiv thaiv kev ua haujlwm dej hiav txwv, txo tus nqi thiab hloov tus nqi.
Kuj yog kev ntxhov siab: Inconal kav muaj kev ntxhov siab rau corrosion (xws li tsim nyog rau cov corrosion), xws li tsim nyog tau tsim thiab tsim nyog siv qauv . 'theem thiab' theem tsim los ntawm cov alloy los ntawm kev ua haujlwm ntawm kev ua haujlwm ntawm kev ua haujlwm ntawm kev ua haujlwm ntawm kev ua haujlwm xws li petrochemicals thiab nuclear Kev lag luam uas muaj kev ntxhov siab thiab corrosion yog sib xyaw ua ke.
Intergranular corrosion: los ntawm cov txheej txheem kho cua sov tsim nyog, yog cov khoom siv chromium tsis kam lees qhov kev ua kom zoo (feem ntau} thaj tsam . Piv txwv li, tsis muaj kev sim hauv e txheej txheem (Otm ARCROLYTIC corrosion .
Tshuaj lom neeg stability: incono}}}}}}}}}} Nyob rau hauv cov kua qaub medic accet, thiab lwm yam daim ntawv nyob rau saum npoo ntawm lub raj alloy, tiv thaiv cov leeg ntshav ntxiv, hauv cov roj ntsha li cas los xij, hauv cov roj ntsha li qub acidizing, muaj cov roj ntsha tsis zoo li cas, cov xeb tsawg ntawm cov alloy Tube yuav sib tw rau ib qho, thiab nws yuav tsum tau raug ntsuas thiab xaiv tau cov tshuaj lom neeg ntau, thiab siv tau rau hauv cov xwm txheej sib txawv, thiab tuaj yeem siv rau hauv cov xwm txheej sib xws xws li Raws li Alkaline cov khoom siv thauj khoom pipelines.
