Nyob rau hauv lub tshav pob ntawm cov yeeb nkab connectors, flanges yog ib qho kev tivthaiv heev. Txawm li cas los xij, thaum cov khoom siv flange hloov los ntawm cov hlau tsis muaj steel mus rau titanium alloy, qhov kev hloov khoom yooj yim zoo li no ua rau muaj kev hloov pauv zoo hauv cov ntsiab lus engineering. Qhov ceev ntawm titanium tsuas yog 4.51 g / cm³, kwv yees li 57% ntawm cov hlau. Rau tib lub flange specification, titanium flange hnyav ze li ib nrab ntawm ntau npaum li lub flange steel. Qhov txiaj ntsig dab tsi ua rau qhov 40% qhov hnyav txo tau coj? Cia peb suav hnub no.
PART.01 Qhov Zoo Tshaj Plaws Los Ntawm Qhov Twg?
Ua ntej, cia saib ib txheej ntawm cov ntaub ntawv yooj yim:
| Cov khoom sib piv | Titanium alloy TC4 | 316L Stainless hlau |
|---|---|---|
| Qhov ceev (g / cm³) | 4.51 | 7.98 |
| Tensile zog (MPa) | Ntau dua lossis sib npaug rau 895 | 515-690 |
Qhov ceev ntawm titanium tsuas yog kwv yees li 57% ntawm stainless hlau, tab sis nws lub zog yog siab dua. Lub zog tensile ntawm TC4 titanium alloy tuaj yeem ncav cuag tshaj 895 MPa, deb tshaj li ntawm 316L stainless hlau. Qhov no txhais tau hais tias nyob rau hauv tib lub zog yuav tsum tau, titanium flanges tuaj yeem ua tiav tib lub load-cov kabmob muaj nuj nqi nrog cov phab ntsa nyias nyias thiab qhov hnyav tag nrho. Kev txo qis 40% tsis ua tiav los ntawm kev txi lub zog; es, nws yog "dawb lightweighting" ua tiav thaum ua kom ntseeg tau lossis txawm tias txhim kho kev ua tau zoo.
PART.02 Qhov 40% Qhov Ntsuas Qhov Ntsuas Qhov Ntsuas Li Cas hauv Engineering?
Kev lag luam Marine:
Txuag ntau tons ntawm qhov hnyav ntawm ib qho roj tanker.
Lub 110,000-tuj roj tanker xav tau ntau dua 32,500 flange txuas cov ntsiab lus hauv nws cov kav dej. Hloov tag nrho stainless hlau flanges nrog titanium flanges tuaj yeem ua tiav qhov hnyav tag nrho ntawm ntau dua 40%. Raws li lub nkoj 自重 (deadweight) txo qis, roj noj poob qis. Nyob rau tib lub sijhawm, cargo muaj peev xwm nce, tso cai rau tib lub nkoj thauj khoom ntau dua thiab ua kom tau nyiaj ntau dua. Ntxiv mus, lub neej kev pab cuam ntawm titanium flanges nyob rau hauv sulfide- muaj seawater yog ntau tshaj tsib npaug ntawm stainless hlau flanges, tiag tiag ua tiav "ib qho kev teeb tsa, ntau xyoo ntawm kev ua haujlwm tsis muaj kev saib xyuas."
Kev lag luam tshuaj:
Kev txo cov yeeb nkab hnyav ua rau txo qis hauv cov qauv kev txhawb nqa.
Hauv cov nroj tsuag tshuaj, cov kav dej feem ntau ncav cuag ob peb mais, nrog ntau pua lossis ntau txhiab flanges. Tom qab siv titanium flanges, tus naj npawb thiab cov ntsiab lus ntawm cov yeeb nkab txhawb nqa thiab cov hangers tuaj yeem raug txo qis, kev thauj khoom ntawm cov yeeb nkab khib nyiab txo qis, thiab cov nqi tsim kho pej xeem poob raws li. Qhov hnyav ntawm ib qho titanium flange tsuas yog ib nrab ntawm cov hlau tsis muaj steel, ua rau nws yooj yim dua rau cov neeg ua haujlwm los tuav, ua kom zoo, thiab nruj bolts, txhim kho kev ua haujlwm zoo.
Aerospace:
Txhua gram ntawm qhov hnyav tseem ceeb rau tus nqi.
Kev txo qis ntawm 1 kilogram ntawm lub dav hlau tuaj yeem txuag tau ntau txhiab daus las hauv cov nqi roj hauv nws lub neej tag nrho. Titanium alloy flanges yog dav siv nyob rau hauv dav hlau cav thiab hydraulic piping, thiab lawv lub teeb yuag yog qhov tseem ceeb rau kev txhim kho roj efficiency.
PART.03 "Hidden Benefits" Tshaj Txoj Kev Nyuaj Siab
Qhov zoo ntawm titanium flanges mus deb tshaj qhov hnyav. Thaum cov khoom lag luam tuaj yeem ua tiav "lub teeb, muaj zog dua, thiab ntau dua corrosion-resistant," nws cov nqi engineering yog sib xyaw.
Corrosion Resistance:
Ntau xyoo kev txij nkawm- lub neej dawb.
Titanium nto cia li tsim ib tug ntom oxide zaj duab xis, ua rau lawv ruaj khov heev nyob rau hauv corrosive ib puag ncig xws li seawater, chloride ions, thiab acids / alkali. TA2 titanium flanges muaj kev pab cuam lub neej ntau tshaj 8 xyoo hauv chlor-alkali nroj tsuag, nrog rau tus nqi qis dua 0.1%. Nyob rau hauv sib piv, stainless hlau flanges yog corroded nyob rau hauv tsuas yog ob peb xyoos nyob rau hauv sulfide - muaj seawater. Kev saib xyuas-kev ua haujlwm pub dawb txhais tau tias txo qis hauv kev tsim khoom kaw rau kev kho thiab txo qis hauv cov khoom seem seem.
Tsis yog -Magnetic Properties:
Tiv thaiv cov khoom siv navigation.
Titanium flanges tsis yog - cov khoom sib nqus, uas tuaj yeem zam kev cuam tshuam ntawm electromagnetic cuam tshuam nrog cov khoom siv hauv nkoj thiab cov cuab yeej precision. Cov yam ntxwv no tseem ceeb tshwj xeeb tshaj yog nyob rau hauv cov xwm txheej ntom ntom nrog siab - cov khoom siv hluav taws xob muaj tseeb.
PART.04 Crunching tus naj npawb: Puas yog Titanium Flanges "Kim kim tab sis pheej yig siv"?
Ntau tus neeg siv khoom thawj zaug thaum pom cov lus qhia rau titanium flanges yog: "Lawv kim dua li cov hlau tsis muaj steel." Txawm li cas los xij, kev lag luam yuav tsum tau saib tag nrho cov nqi ntawm lub neej, tsis yog tus nqi pib yuav khoom xwb. Nyob rau hauv ib puag ncig corrosive heev xws li chlor-alkali, seawater desalination, thiab marine engineering, lub voj voog hloov rau stainless hlau flanges yuav tsuas yog 3-5 xyoo, thaum titanium flanges tuaj yeem kav ntev dua 20 xyoo. Thaum cov nqi hloov pauv, cov khoom poob los ntawm kev kaw, thiab cov khoom seem ntawm cov khoom lag luam yog tag nrho cov txiaj ntsig, qhov ntev -kev lag luam ntawm titanium flanges deb tshaj cov hlau tsis muaj steel. "Kim yuav tab sis pheej yig siv" yog qhov tseeb tshaj plaws tus nqi profile ntawm titanium flanges.
Raws li lub tuam txhab "Specialized thiab Sophisticated" kev lag luam thiab kev tswj hwm kev lag luam saum toj no qhov loj me hauv Shaanxi Xeev, Lihua Titanium tau tsom mus rau titanium flanges rau 20 xyoo, pab ntau tshaj 5,000 lub lag luam daws teeb meem corrosion hauv lawv cov lag luam. Yog xav paub ntxiv, thov ua raws li WeChat pej xeem tus account "Lihua Titanium" thiab tawm koj lub tuam txhab npe thiab cov ntaub ntawv tiv tauj. Peb yuav muab koj nrog cov kws tshaj lij los tiv thaiv - kev daws teeb meem corrosion.
