Kev ceev faj thaum cov ntsiab lus hydrogen siab dhau lawm
Kev npaj los txo qhov nqus hydrogen
Ua ntej kev kho cua sov, yuav tsum tau ua kom tiav thiab ua tib zoo tu cov titanium raj fittings. Cov ntiv tes, sib tsoo cov cim, roj, thiab lwm yam khoom seem tuaj yeem yog qhov chaw ntawm hydrogen absorption, yog li nws yog qhov tseem ceeb los xyuas kom meej tias cov tshuaj no raug tshem tawm kom huv si. Tsuas yog los ntawm kev ua qhov kev npaj ua haujlwm no tuaj yeem nqus cov hydrogen los ntawm titanium raj fittings thaum ua haujlwm tom ntej yuav txo tau zoo.
Kev tswj ntawm qhov chaw kho cua sov
Qhov chaw nyob rau hauv lub qhov cub kho cua sov yog qhov tseem ceeb rau qhov zoo ntawm titanium raj fittings. Nws yog ib qho tsim nyog los xyuas kom meej tias tsis muaj dej vapor nyob rau hauv lub qhov cub kho cua sov, vim dej vapor tuaj yeem hnov mob nrog titanium thiab nce hydrogen nqus. Yog hais tias cov ntsiab lus hydrogen ntawm lub titanium raj fittings tau tshaj tus nqi tso cai, lub tshuab nqus tsev yuav tsum tau siv los tshem tawm cov dej ntau dhau.
Oxidation thiab paug cov teeb meem thaum lub sij hawm siab -kev kho cua sov
Thaum lub tshav kub kho kub tsis tshaj 540 degrees, oxide zaj duab xis ntawm titanium raj fittings yuav tsis thicken ho. Txawm li cas los xij, ntawm kev kho cua sov ntau dua, tus nqi oxidation yuav nce ntxiv, thiab cov txheej txheem sab hauv ntawm cov khoom oxidized yuav tsim ib txheej ntawm cov kab mob. Cov pa paug paug txheej txheej no muaj qhov sib piv siab brittleness thiab tuaj yeem ua rau tawg yooj yim thiab puas ntawm qhov chaw. Txhawm rau tshem tawm cov kab mob deoxidation no, kev siv tshuab ua haujlwm, kua qaub ntxuav, thiab tshuaj sib tsoo tuaj yeem siv. Thaum lub sij hawm kho cua sov txheej txheem, kom txo tau qhov cuam tshuam ntawm oxidation, lub sij hawm cua sov yuav tsum tau luv kom ntau li ntau tau thaum ua kom muaj kev tiv thaiv kev kho cua sov. Nyob rau tib lub sijhawm, lub tshuab nqus tsev vacuum los yog cov roj cua tsis zoo yuav tsum raug xaiv rau kev kho cua sov, thiab cov cua sov titanium raj fittings hauv cov cua sov yuav tsum zam lossis txo kom tsawg kom tsis txhob muaj kab mob.
Cov yam ntxwv ntawm titanium raj fittings
Zoo heev corrosion kuj
Titanium yog cov hlau reactive heev uas muaj qhov sib npaug qis heev thiab muaj zog thermodynamic corrosion nyiam hauv xov xwm. Txawm li cas los xij, hauv oxidizing, nruab nrab, thiab tsis muaj zog txo cov xov xwm, titanium qhia tau hais tias zoo stability thiab zoo heev corrosion kuj. Qhov no ua rau titanium raj fittings dav siv nyob rau hauv ntau lub teb nrog siab yuav tsum tau rau corrosion kuj.
Zoo kub tsis kam
Titanium tube fittings muaj cua sov zoo thiab tuaj yeem siv tau ntev ntawm qhov kub txog li 600 degrees lossis siab dua. Cov yam ntxwv no muab cov titanium raj fittings tshwj xeeb kom zoo dua nyob rau hauv siab - qhov chaw ua haujlwm kub thiab tuaj yeem ua tau raws li cov kev cai siv ntawm kev ua haujlwm tshwj xeeb.
Tsis yog- sib nqus thiab tsis yog- tshuaj lom
Titanium alloy tube fittings tsis yog - hlau nplaum thiab yuav tsis raug hlau nplaum txawm nyob hauv cov hlau nplaum muaj zog. Nyob rau tib lub sijhawm, lawv tsis yog - lom, uas ua rau cov titanium raj fittings muaj cov txiaj ntsig tseem ceeb hauv cov teb xws li kev kho mob thiab hluav taws xob uas muaj cov kev cai nruj rau cov khoom siv hlau nplaum thiab toxicity.
Tsawg elastic modulus
Lub elastic modulus ntawm titanium raj fittings yog tsawg, tsuas yog 57% ntawm cov hlau. Qhov qis elastic modulus ua rau titanium raj fittings muaj kev yooj yim dua thiab deformation muaj peev xwm thaum raug quab yuam, thiab tuaj yeem ua tau raws li qhov yuav tsum tau muaj ntawm qee qhov kev xav tau siab rau cov khoom elasticity.
Active absorption kev ua tau zoo
Titanium tube fittings yog cov khoom siv hlau uas tuaj yeem ua rau muaj ntau lub ntsiab lus thiab cov khoom sib txuas ntawm qhov kub thiab txias. Txawm hais tias qhov kev ua tau zoo ntawm kev nqus no nce qhov nyuaj ntawm kev ua haujlwm rau qee qhov, nws kuj tseem muab qhov ua tau rau kev sib xyaw thiab kev hloov kho ntawm titanium raj fittings nrog rau lwm cov ntaub ntawv, uas yog qhov tsim nyog rau kev txhim kho titanium-raws li cov ntaub ntawv sib xyaw nrog kev ua tau zoo dua.
Hauv cov ntsiab lus, hauv kev ua cov titanium raj fittings, kev saib xyuas zoo yuav tsum tau them rau qhov teeb meem ntawm cov ntsiab lus hydrogen ntau dhau thiab kev ua haujlwm yuav tsum tau ua nruj me ntsis raws li kev ceev faj. Nyob rau tib lub sijhawm, kev nkag siab zoo ntawm cov yam ntxwv ntawm titanium raj fittings tuaj yeem ua kom zoo dua lawv qhov zoo thiab nthuav dav lawv daim ntawv thov.
