Thaum cov ntsiab lus hydrogen hauv titanium yeeb nkab fittings siab dhau lawm, qhov cuam tshuam toughness thiab notch tensile lub zog yuav txo qis vim brittleness. Yog li ntawd, nws feem ntau tau teev tseg tias cov ntsiab lus hydrogen hauv titanium yeeb nkab fittings yuav tsum tsis pub tshaj 0.015 feem pua. Txhawm rau txo qhov nqus ntawm hydrogen, cov ntiv tes, abrasions, roj, thiab lwm yam khoom seem yuav tsum tau ntxuav ua ntej kev kho cua sov. Tsis muaj dej vapor hauv qhov cub kho cua sov. Thaum cov ntsiab lus hydrogen ntawm titanium yeeb nkab fittings tshaj qhov tso cai, lub tshuab nqus tsev annealing yuav tsum tau ntxuav.
Thaum qhov kub tsis siab tshaj 540 degrees, oxide zaj duab xis ntawm titanium yeeb nkab fittings yuav tsis ua thicker, tab sis nyob rau hauv lub kub kho kub kub, oxidation tus nqi yuav ceev, thiab nyob rau hauv lub diffusion txheej ntawm cov khoom oxidized yuav dhau los ua ib txheej ntawm ua paug. Cov pa pa phem txheej txheej muaj qhov sib piv siab brittleness, ua rau tawg thiab puas ntawm qhov chaw. Cov txheej txheem deoxygenation muaj xws li cov txheej txheem xws li kev siv tshuab, tshuaj ntxuav kua qaub, thiab tshuaj sib tsoo. Thaum kho cua sov, thaum tiv thaiv kev kho cua sov, sim ua kom lub sijhawm cua sov kom tsawg li ntau tau. Nws tseem tuaj yeem nqa tawm hauv lub tshuab nqus tsev vacuum lossis lub qhov cub tsis muaj roj, thiab cov pa phem los ntawm cua sov ntawm titanium yeeb nkab fittings nyob rau hauv lub cub tawg yuav tsum raug zam los yog txo kom zoo.
Nta ntawm titanium yeeb nkab fittings:
1. Corrosion kuj ntawm titanium yeeb nkab fittings. Titanium yog cov hlau muaj zog heev nrog qhov sib npaug qis thiab muaj zog thermodynamic corrosion nyiam nyob rau hauv nruab nrab. Titanium muaj kev ruaj ntseg zoo thiab corrosion kuj nyob rau hauv ntau yam xov xwm xws li oxidation, neutrality, thiab tsis muaj zog txo.
2. Titanium yeeb nkab fittings muaj cua sov zoo. Nws tuaj yeem siv rau lub sijhawm ntev ntawm qhov kub ntawm 600 degrees lossis siab dua.
3. Tsis muaj hlau nplaum, tsis muaj tshuaj lom, titanium alloy yeeb nkab fittings yog cov hlau tsis sib nqus uas yuav tsis raug hlau nplaum hauv cov hlau nplaum siab.
4. Tsawg elastic modulus, 57 feem pua steel.
5. Kev nqus pa ua haujlwm. Titanium yeeb nkab fittings yog ib yam hlau uas muaj peev xwm hnov mob nrog ntau yam khoom thiab cov khoom sib txuas ntawm qhov kub thiab txias.
