U-Tubes Rau Cov Hluav Taws Xob Hluav Taws Xob: Qhov Zoo Tshaj Plaws Thiab Cov Ntawv Thov Kev Lag Luam
Raws li ib feem tseem ceeb ntawm lub plhaub thiab lub raj kub exchangers,U-Tubes rau Kub Exchangersyog dav siv nyob rau hauv marine, petrochemical, lub zog tsim, tub yees thiab lwm yam lag luam vim lawv cov qauv tsim tshwj xeeb thiab kev ua tau zoo heev. Sib txawv ntawm cov raj ncaj nraim, U- cov raj zoo li tuaj yeem hloov kho rau thermal expansion thiab contraction, txo cov khoom puas tsuaj los ntawm qhov kub thiab txias, thiab dhau los ua ib feem tseem ceeb ntawm siab - kev cia siab rau cov cua sov hloov pauv. Tsab ntawv xov xwm no yuav tsom mus rau cov yam ntxwv ntawm cov qauv, cov txiaj ntsig tseem ceeb thiab kev siv cov xwm txheej ntawm U-tub rau cov khoom siv hluav taws xob, muab cov ntaub ntawv muaj txiaj ntsig zoo rau cov neeg siv khoom thoob ntiaj teb hauv kev xaiv cov khoom thiab kev saib xyuas.
U-Tubes rau Kub Exchangersmuaj npe rau lawv cov U-zoo li tus qauv dabtsi yog khoov, uas feem ntau yog tsim los ntawm ib leeg khoov raj (feem ntau yog 180℃dabtsi yog khoov) thiab txuas cov pob qij txha, thiab feem ntau yog siv los ua cov ntsiab lus tseem ceeb ntawm U- raj plhaub thiab lub raj kub exchangers. Qhov zoo tshaj plaws ntawm cov qauv ntawm U- raj yog tias lawv tuaj yeem paub qhov kev nthuav dav dawb thiab kev cog lus nyob rau hauv qhov kub thiab txias siab -thaum lub tshav kub exchanger ua haujlwm, qhov kub sib txawv ntawm lub raj sab thiab lub plhaub sab nruab nrab yuav ua rau lub raj lub cev nthuav dav lossis ntsws, thiab U- zoo li tus qauv tuaj yeem nqus cov thermal deformation los ntawm nws tus kheej lub raj los ntawm kev puas tsuaj los ntawm cov phaj phaj, thiab cov phaj sib txawv ntawm qhov sib txawv. yog li zoo heev txhim kho lub neej kev pabcuam thiab kev ua haujlwm ruaj khov ntawm cov khoom siv hluav taws xob.
Hais txog kev xaiv cov khoom, U-Tubes rau Kub Exchangersraug kho raws li kev ua haujlwm sib txawv kom ntseeg tau tias muaj kev tiv thaiv corrosion, kub tsis kam thiab siab ua haujlwm. Rau cov dej hiav txwv thiab dej hiav txwv, peb txais titanium U- raj thiab tooj liab-nickel alloy (90/10, 70/30) U- raj, uas tuaj yeem tiv taus dej hiav txwv corrosion thiab marine atmospheric erosion, thiab tau siv dav hauv marine condensator, dej qab zib generators. Rau cov chaw petrochemical thiab tshuaj lom neeg nrog cov xov xwm muaj zog corrosive, 304/316L stainless hlau U- raj raug xaiv los hloov mus rau cov kua qaub- puag, cov kuab tshuaj organic thiab lwm yam kev ua haujlwm hnyav. Rau siab - kub thiab siab - lub zog tsim hluav taws xob, siab - kub alloy U- cov raj siv los xyuas kom ruaj khov ua haujlwm nyob rau hauv huab cua txias.
Piv nrog rau cov raj xa hluav taws xob ncaj nraim, U- cov raj muaj qhov zoo tshaj plaws hauv kev siv tswv yim: ua ntej, lawv muaj zog yoog rau thermal kev nyuaj siab, uas yog tsim rau cov cua kub exchangers nrog kub kub sib txawv ntawm lub raj sab thiab plhaub sab, xws li fais fab nroj tsuag condensers thiab petrochemical reactor coolers; Thib ob, cov qauv yog yooj yim thiab cov txheej txheem tsim khoom yog qhov paub tab, uas tuaj yeem txo qhov nyuaj ntawm lub raj ntim cov khoom sib dhos thiab kev saib xyuas -U- raj bundles tsis tas yuav ntab raj phaj, thiab cov qauv ntawm cov khoom siv hluav taws xob sib txuas yog ntau compact, txuag cov khoom siv; thib peb, tus nqi kho mob tsawg. Thaum ib tus neeg U- cov raj puas lawm, lawv tuaj yeem txuas ncaj qha lossis hloov pauv yam tsis muaj kev cuam tshuam tag nrho cov hlua khi, uas ua rau lub voj voog tu thiab txo cov nqi tu.
Hais txog kev siv scenarios,U-Tubes rau Kub Exchangersmuaj ntau yam kev siv thiab npog ntau yam kev lag luam tseem ceeb. Hauv kev lag luam marine, lawv tau siv rau hauv marine plhaub thiab raj condensers, marine roj coolers thiab dej tshiab generator evaporators, uas tuaj yeem hloov mus rau qhov hnyav marine ib puag ncig thiab ua kom ruaj khov ntawm lub nkoj fais fab. Hauv kev lag luam petrochemical, U- raj yog siv hauv catalytic cracking unit coolers, distillation ntau condensers thiab hnyav rov qab kub exchangers, uas muaj peev xwm tiv taus corrosion ntawm hnyav xov xwm thiab paub tau zoo tshav kub exchangers. Hauv kev lag luam hluav taws xob tsim hluav taws xob, U- raj kub exchangers yog siv nyob rau hauv chav condensers thiab boiler pub dej rhaub, uas tuaj yeem hloov mus rau qhov kub thiab txias ua haujlwm siab thiab txhim kho kev ua haujlwm ntawm lub tshuab hluav taws xob.
Tsis tas li ntawd, U-tubes kuj tau siv dav hauv cov tub yees thiab cua txias, cov tshuab boiler thiab cov khoom siv hluav taws xob tawm sab nraud. Piv txwv li, nyob rau hauv loj hauv nruab nrab cua txias tshuab, U- raj kub exchangers yog siv los paub txog cov cua kub pauv ntawm cov tub yees thiab dej txias, txhim kho lub tub yees efficiency; nyob rau hauv offshore platforms, titanium U- raj yog siv los hloov mus rau qhov muaj zog corrosion ntawm dej hiav txwv, kom ntseeg tau tias kev ua haujlwm ntawm cov khoom siv roj thiab cov khoom siv hauv ntug dej hiav txwv.
Raws li cov kws tshaj lij ntawm cov khoom siv hluav taws xob sib txuas, peb muaj kev paub ntau yam hauv kev tsim khoom thiab kev hloov kho ntawm U-Tubes rau Kub Exchangers. Peb cov U- raj yog tsim nyob rau hauv nruj raws li thoob ntiaj teb cov qauv, nrog meej dabtsi yog khoov cov ces kaum, uniform tube phab ntsa thickness thiab nruj kev ntsuam xyuas thiab corrosion xeem ua ntej tawm hauv lub Hoobkas, xyuas kom meej cov khoom zoo thiab kev ua tau zoo. Peb kuj tuaj yeem hloov kho U- raj ntawm cov khoom sib txawv, cov khoom siv thiab khoov radii raws li cov neeg siv khoom kos duab kos duab thiab kev ua haujlwm tiag tiag, kom tau raws li tus kheej xav tau ntawm kev lag luam sib txawv.
Nws yog ib qho tsim nyog yuav tsum nco ntsoov tias lub neej kev pab cuam ntawm U-tubes muaj feem cuam tshuam nrog kev saib xyuas txhua hnub. Peb xav kom cov tuam txhab lag luam thiab cov neeg siv niaj hnub ntxuav cov phab ntsa sab hauv thiab sab nrauv ntawm U- raj kom tsis txhob scaling thiab fouling, uas cuam tshuam rau kev sib pauv cua sov; tsis tu ncua xyuas qhov dabtsi yog khoov ntawm U- raj rau cov kab nrib pleb thiab corrosion, thiab cuam tshuam nrog cov kev ua yuam kev hauv lub sijhawm. Nyob rau tib lub sijhawm, peb pab neeg ua haujlwm muab kev tshaj lij tom qab- kev txhawb nqa muag, suav nrog kev taw qhia txog kev xaiv cov khoom, ntawm -cov kev taw qhia kev teeb tsa thiab kev kuaj xyuas qhov tsis raug, los pab cov neeg siv khoom kom muaj txiaj ntsig zoo tshaj plaws ntawm U- raj.
Nrog rau kev txhim kho txuas ntxiv ntawm kev lag luam thiab kev xav tau ntau ntxiv rau kev txuag hluav taws xob thiab txo qis qis, U-Tubes rau Cov Hluav Taws Xob Hluav Taws Xob, raws li qhov siab - kev ntseeg siab, siab - cov khoom siv hluav taws xob sib pauv tau zoo, yuav ua lub luag haujlwm tseem ceeb hauv kev lag luam thoob ntiaj teb. Peb tseem yuav tsom mus rau kev tshawb fawb cov khoom lag luam thiab kev tsim kho thiab kev txhim kho kom zoo, muab siab - zoo U- cov khoom siv raj thiab cov kev daws teeb meem rau cov neeg siv khoom thoob ntiaj teb, pab cov neeg siv khoom txhim kho cov cuab yeej ua haujlwm zoo, txo cov nqi tu, thiab ua tiav kev txhim kho kom ruaj khov.
