Yuav ua li cas mus cuag lub neej kev pab cuam ntawm titanium raj?
Yuav ua li cas txhim kho lub neej ntawm titanium kav? Kev txhim kho lub neej kev pab cuam ntawm titanium yeeb nkab fittings tau dhau los ua qhov teeb meem kev kawm tseem ceeb hauv kev tsim tshuab raj raj.
Titanium pipelines mas thauj corrosive thiab txaus ntshai xov xwm. Thaum corrosive xov xwm dhau los ntawm titanium yeeb nkab fittings, qhov nruab nrab yuav muaj qee qhov siab. Txhua feem ntawm ntau yam yeeb nkab fittings nqa ntau qhov sib txawv. Peb feem ntau siv yeeb nkab fittings (lub luj tshib, tee, reducer) los soj ntsuam. Cov txheej txheem thawb lub luj tshib yog lub luj tshib steel tshiab tsim cov cuab yeej qhia rau kuv lub teb chaws los ntawm Nyiv nyob rau hauv nruab nrab mus rau lig 1980s. Vim tias cov txheej txheem no ua rau kev tsim khoom tas mus li thiab tsim lub luj tshib nrog cov phab ntsa tuab, nws hloov cov txheej txheem ib txwm ua sai sai. Peb tau ua tiav tsim seamless titanium yeeb nkab fittings xws li seamless titanium tees thiab seamless reducers. Qhov siab tshaj plaws ntawm seamless yeeb nkab fittings tuaj yeem ncav cuag Φ219 thiab ua tau raws li ASTM B363-95 tus qauv yuav tsum tau ua. Cov txiaj ntsig kev sim uas siv txoj hauv kev network tau lees paub tias qhov deformation thaum lub luj tshib tsim feem ntau tshwm sim hauv qhov qis. Ib daim phiaj sib xws yog kos rau ntawm qhov khoob. Thaum lub sij hawm molding, nws tuaj yeem pom tias daim phiaj tsis hloov ntau thaum lub nraub qaum ntawm lub luj tshib yog tsim. Qhov loj dua qhov deformation ua thaum lub plab deformed, daim phiaj yog elongated nyob rau hauv lub voj voog kev taw qhia thiab compressed nyob rau hauv lub axial kev taw qhia, tab sis tag nrho cov cheeb tsam ntawm daim phiaj tsis hloov, qhia tau hais tias tsis muaj qhov pom tseeb hloov nyob rau hauv lub thickness kev taw qhia.
Kev ua haujlwm ntawm lub laub-ua titanium lub luj tshib siv seamless titanium raj ua qhov khoob. Ntawm lub tshuab thawb-extrusion tshwj xeeb, qhov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob. Txoj kev tuag yog tsau rau ntawm lub tshuab tseem ceeb thiab muaj lub zog txav txav los thawb nws. Lub raj blank nce mus rau sab xis mus rau sab laug. Thaum lub qhov khoob yog nyob rau hauv txoj kev pwm, nws yog rhuab thiab tiv thaiv. Thaum lub sij hawm tsim cov txheej txheem, lub raj raj yog nthuav. Kev tsom xam ntawm lub zog thaum lub sij hawm tsim cov txheej txheem qhia tau hais tias lub zog loj ntawm qhov sib txawv yog txawv, tab sis lawv yog ob qho tib si compressed nyob rau hauv ob txoj kev thiab stretched nyob rau hauv ib qho kev taw qhia, uas yog, axial compression, radial compression, thiab circumferential nro. Thaum lub sij hawm tag nrho cov txheej txheem deformation, txoj kab uas hla maj mam nce, khoov, thiab qhov ntev shortens thaum lub thickness tseem tseem tsis hloov.
cov khoom zoo heev ntawm cov kav dej titanium ua rau lawv muaj kev nqis peev zoo rau txhua qhov kev lag luam. Txhawm rau kom cov kav dej no kav ntev, lawv yuav tsum tau nruab kom raug, khaws cia tsis tu ncua, tiv thaiv corrosion, tuav kom raug, thiab ua haujlwm hauv cov xwm txheej tsim nyog. Los ntawm kev ua raws li cov kev cai no, kev pab lub neej ntawm titanium kab tuaj yeem nthuav dav, muab cov txiaj ntsig ntev ntev kom deb li deb ntawm tus kheej lub sijhawm thiab cov nqi tu.
Muaj ob peb lwm txoj hauv kev uas tuaj yeem txuas lub neej ntawm cov kav dej titanium:
1.Nruam kom raug
Kev txhim kho lub titanium raj kom raug yog thawj kauj ruam tseem ceeb tshaj plaws kom ncua nws txoj kev pab cuam lub neej.Cov kav dej yuav tsum tau ua tib zoo ntxuav ua ntej lawv tuaj yeem ntsia tau kom tshem tawm cov kab mob uas tuaj yeem ua rau xeb. Cov kab yuav tsum zoo ib yam li kev ruaj ntseg thiab ruaj khov kom tsis txhob muaj dej nchuav. Tsis tas li ntawd, nws yog ib qho tseem ceeb kom lav tias cov kab tsis raug rau qhov tsis muaj qhov tsis muaj zog los yog kev poob siab thaum lub sij hawm tsim.
2. Kev them nyiaj yug li qub
Kev txhawb nqa ib txwm yuav tsum ua kom cov kav dej titanium saib zoo thiab ua rau muaj kev poob siab tsis tu ncua. Cov kab yuav tsum tau tshuaj xyuas kom pom tias muaj kev puas tsuaj, xws li yaig lossis tawg, thiab kho raws li qhov xav tau yuav tsum tshwm sim. Txhua qhov fittings dawb lossis cinches yuav tsum tau kho, thiab txhua qhov kev tso tawm yuav tsum tau kho kom nrawm. Kev tu kev lis kev cai kuj tseem ceeb heev kom tshem tawm txhua qhov kev loj hlob ntawm impurities uas tuaj yeem ua rau noj.
3. Kev tiv thaiv corrosion
Kev Tiv Thaiv Corrosion Hauv cov kav dej titanium, corrosion yog feem ntau ua rau tsis ua hauj lwm. Txhawm rau txhawm rau txhawm rau noj, nws yog qhov yooj yim los xaiv qhov zoo ntawm titanium composite thiab lav tias nws siv tau nrog cov kua nws yuav xa. Ib txheej uas tiv thaiv corrosion yuav xav tau ntawm cov kav dej yog tias cov kua dej corrosive. Los ntawm kev siv hluav taws xob tam sim no rau cov kav dej, kev tiv thaiv cathodic kuj tuaj yeem siv los tiv thaiv corrosion los ntawm neutralizing cov corrosive agents.
4. Kov nws kom raug
Titanium cov kav dej tsis tuaj yeem raug puas tsuaj tshwj tsis yog tias lawv ua haujlwm zoo. Lawv yuav tsum cia li txav mus thiab muab tso rau hauv ib qho kev nyab xeeb uas tsim nyog rau forestall qhib rau dampness thiab impurities. Txhawm rau kom tsis txhob muaj kev puas tsuaj, cov kav dej yuav tsum tau ua tib zoo saib xyuas thaum lub sijhawm teeb tsa thiab kev saib xyuas.
5. Cov xwm txheej ua haujlwm
Cov kav dej titanium yuav tsum tau ua haujlwm hauv lawv txoj kev npaj ciam teb kom tiv thaiv kev poob siab tsis tu ncua. Qhov no txhais tau hais tias qhov kub thiab txias, lim, thiab cov dej ntws yuav tsum tsis txhob dhau cov ntsiab lus txiav tawm los ntawm tus tsim khoom. Txhawm rau kom tsis txhob ua rau cov kav dej puas, txhua qhov kev hloov pauv rau kev ua haujlwm yuav tsum tau ua tib zoo soj ntsuam.
6. Zam kev puas tsuaj
Tsis txhob muaj kev puas tsuaj rau cov khoom siv: Tsis txhob muaj kev puas tsuaj rau cov titanium raj thaum tuav, teeb tsa thiab siv. Tiv thaiv kev cuam tshuam, crushing lossis lwm yam kev puas tsuaj rau lub cev.
