Cov txheej txheem ntawm ntau tus neeg cov tsev so tsib lub hnub qub xav tau kev siv cov khoom lag luam tooj liab rau cov khoom siv hluav taws xob, tab sis yog vim li cas thiab ntau dua cov khw muag khoom siv. Kab lus no tsuas yog ua rau kev sib piv txuj ci ntawm tooj liab kav thiab stainless hlau kav hlau. , rau kev siv.
1. Piv ntawm tooj liab yeeb thiab stainless hlau yeeb nkab
Tam sim no piv txog kev ua yeeb yam ntawm lub cev, kev ua tau zoo, corrosion tsis kam thiab nyiaj txiag muaj txiaj ntsig ntawm cov ntaub ntawv.
1) sib piv ntawm cov khoom siv lub cev
Kev sib piv ntawm lub zog tensile:
Noj cov feem ntau siv rho-walled stainless hlau yeeb nkab tsim los ntawm 304-750m50MPA, uas yog ob zaug uas yog cov yeeb nkab uas yog cov yeeb nkab tooj liab. Yog li ntawd, nyias-walled-walled stainless hlau yeeb nkab tuaj yeem ua tau thinner, uas yog qhov lav ntawm lub zog, thiab tuaj yeem ua tiav lub hom phiaj ntawm kev txo cov khoom lag luam
2) Kev sib piv ntawm Thermal Condivity:
Lub thermal conductivity ntawm nyias-walled stainless hlau yeeb nkab hlau yog 15 ° C (100 ° C (100/23 ntawm ntawd tooj liab cov yeeb nkab. Thin-wall stainless hlau kav yog tshwj xeeb tshaj yog haum rau cov dej kub thauj mus vim lawv txoj kev ua haujlwm zoo rwb thaiv tsev. Txawm hais tias nws yog lub thickness ntawm rwb thaiv tsev txheej, lossis kev txij nkawm kev tsim kho ntawm cov qauv rwb thaiv tsev, qhov nyias-phab ntsa stainless kav muaj kev lag luam zoo heev.
3) Kev sib piv ntawm cov kev nthuav dav los ntsuas cov coefficients:
Qhov nruab nrab coefficient ntawm thermal expansion ntawm nyias-walled-walled stainless hlau kav yog 0.017mm / (M ° C), uas nyob ze rau ntawm cov kav tooj liab. Cov kav dej hlau yuav tsum siv rau kev thauj khoom kub.
Sab hauv phab ntsa ntawm lub nyias nyias-walled stainless hlau lub raj yog tus mob sab hauv thiab sab nraud ntawm phab ntsa ntawm lub raj yog 0.00152mm, uas yog me dua li ntawm lub raj tooj liab.
Yog li ntawd, kev siv cov nyias nyias-walled stainless hlau kav muaj ntau dua cov dej ntws, zoo dua corrosion tsis kam, thiab txo cov suab nrov
2. Piv ntawm kev ua tau zoo
Lub stainless hlau dej yeeb nkab tshem tawm cov teeb meem ntawm 'dej liab, dej ntsuab thiab zais dej '. Nws tsis muaj peculiar tsw, tsis muaj kev phom sij, ua rau cov dej tsis zoo, ua kom cov dej ua kom huv, thiab tsis muaj teeb meem rau tib neeg lub cev.
Xyoo los ntawm kev siv txawv teb chaws thiab kev kuaj sim hauv cov neeg sib txawv ntawm cov neeg hlau hlau yog ntau tshaj 5% ntawm cov qauv dej hauv lub ntiaj teb hais txog ob tus qauv no). Tsawg.
Qhov tseeb, cov khoom siv stainless hlau muaj kev nyab xeeb, uas tau ua tiav zoo los ntawm cov khoom siv stainless hauv ntau tib neeg kev noj qab haus huv, thiab tau dhau los ua qhov tseeb zoo.
Stainless hlau tsis tau siv tau ntev hauv kev lag luam khoom noj, thiab cov khoom siv ua noj ua haus, thiab ua cov khoom siv ua noj ua haus, thiab ua cov khoom siv ua noj ua haus thiab ua noj ua haus rau cov chaw huv si hauv chav ua lag luam soob tsis tshua muaj neeg huv huv.
Nws paub zoo tias cov kav dej tooj liab tau txais kev rau mob corrosion thiab tsim patina.
Tooj liab kav kev txom nyem los ntawm ntau tshaj li tooj liab, corrosive iab iab me me los ntawm xiav-dej vim tias corrosion, thiab scaling. Lub 'patinous ntsuab ' uas tshwm sim hauv Copper pipes yog tsuas yog muaj los ntawm tooj liab carbonate [CUCO3.CUs Sulfate (Cucper Sulfate (Cucper Sulfate (Cucro4), uas yog qhov yooj yim rau huab cua thiab yaj hauv dej. Txawm hais tias nws tuaj yeem cuam tshuam cov fungi, nws tsis muaj qhov cuam tshuam rau cov kab mob ua tsis tau zoo, uas tau siv cov tshuaj tua kab, kev txhawb nqa ntawm cov tawv nqaij tsis zoo hauv tib neeg lub cev.
Nws tuaj yeem ua rau reflex ntuav thiab muaj qhov muaj zog txhawb cov nyhuv rau cov hnyuv. Cov kev tshawb fawb kho mob niaj hnub no qhia tau tias cov tooj dej haus uas muaj dej haus ntau dhau los yog tsis ncav cuag kev noj qab haus huv.
3. Kev sib piv ntawm corrosion tsis kam
Vim tias cov raj rho tawm uas tsis muaj zog siv tau nrog cov oxidant, muaj peev xwm tiv thaiv kev ua yeeb yam nyuaj thiab ua rau lub cev muaj peev xwm ua tau zoo nkauj heev. Qhov no yog qhov tseem ceeb vim li cas thiaj tiv thaiv corrosion ntawm tooj liab kav dej yog qhov deb dua rau qhov ntawm cov kav hlau nyias stainless hlau.
Thaum siv cov kav dej tooj liab, nws yog ib qho tsim nyog los tswj cov tshuaj lom neeg muaj pes tsawg leeg thiab nrawm ntawm cov dej, txwv tsis pub nws yuav ua rau xeb corrosion. Piv txwv li, kev xeb ntawm tooj liab kav yuav nce ntxiv rau hauv dej nrog PH <6. 6.0PPM, thiab dej muag muag yuav ua rau muaj kev txhim kho corrosion. Thaum siv cov kav dej tooj liab, cov dej ntev yuav tsum tsis pub tshaj 2 m / s, txwv tsis pub tus corrosion tus nqi yuav nce ntxiv.
Thaum tus nqi ntws mus txog 2 m / s, cov yeeb nkab corrosion yog li ntawm 3 m / s, txoj kev sib cav sib ceg yog ntau npaum li 20 zaug uas muaj cov yeeb nkab nyias-phab ntsa nyias nyias.
Tsis tas li ntawd, cov nplaim hluav taws xob liab liab tseem yooj yim rau corrode.
4. Kev sib piv ntawm cov nqi nyiaj txiag
Lub tsev chrysler, nyob hauv New York, Tebchaws Asmeskas, tau tsim nyob nruab nrab ntawm 1926 thiab 1931. Nws yog 318.9 metres siab thiab muaj 77 plag tsev. Nws yog thawj lub tsev nyob hauv lub ntiaj teb los siv cov khoom siv stainless hlau hauv nws sab nrauv.
Txawm hais tias nws ntug hiav txwv thiab qhov chaw muaj kuab paug, lub stainless hlau ntawm nws tseem ci tom qab 80 xyoo, nrog tsuas yog ob leeg ntxuav hauv nruab nrab.
Los ntawm chrysler lub tsev nyob rau hauv New York, tus petronas yees hauv Kuala Lumpur rau Disney Concert Hall nyob rau hauv Los Angeles ua los ntawm cov hlau tsis muaj zog, thiab Waterloo chaw nres tsheb hauv London, Askiv; Rau cov txheej txheem qhov chaw, stainless hlau, raws li cov khoom siv ntsuab ntau tshaj plaws hauv tsev, exudes ib qho kev ntxim nyiam uas cov ntaub ntawv zoo nkauj tsis muaj thoob plaws ntiaj teb.
Cov no yog cov piv txwv zoo tshaj plaws ntawm lub timeless xwm ntawm stainless hlau.
Los ntawm kev tsom xam ntawm kev siv cov hlau nyias-phab ntsa stainless hlau, lub neej kev pabcuam yog tib yam li cov tsev ntawd, uas yog sib npaug ntawm cov kav tooj liab.
Theoretical fight calculation ntawm nyias-wall-walled stainless hlau:
Qhov hnyav rau ib lub 'meter' = (txheej txheej ntawm txoj kab uas hla - tuab)
Tus nqi sib piv ntawm cov kav dej: vim tus nqi tooj liab roj nyoos, tus nqi ntawm cov kav hlau tooj liab uas muaj hnub nyoog li 40% qis dua li cov kav dej tooj liab. Yog li ntawd, tus nqi nyiaj txiag ntawm nyias walled stainless hlau kav yog obviously zoo dua li cov tooj liab kav.
Nyias-walled stainless hlau kav muaj lub neej qis dua li lub neej qis dua cov kav tooj liab.
Vim tias ib zaug cov pipe nyias-walled stainless hlau siv, lawv tsis tas yuav hloov nyob rau hauv lub sijhawm 100-xyoo lub neej tsis tuaj yeem ua tiav lub neej kev pabcuam ntev ntev. Tsuav lawv tau hloov ib zaug hauv lub tsev 70 xyoo ntawm lub tsev, tus nqi ntawm tag nrho yuav muaj tsawg kawg yog 2 txog 4 lub zog ntawm cov kav hlau nyias nyias thiab kav dej.
Qhov tseeb, kev xaiv ntawm cov kav dej stainless hlau tsis tsuas yog muaj qhov qis dua kev nqis peev, tab sis kuj muaj lub neej muaj sia tsawg. Qhov no yog qhov kev khwv tau nyiaj ntau tshaj plaws uas zoo dua ntawm cov hlau stainless tias lwm cov ntaub ntawv tsis tuaj yeem sib phim.
3. Ntsiab lus
Ob qho tib si stainless hlau kav thiab cov kav dej tooj liab yog cov dej ua haujlwm zoo tso dej hlau kav hlau. Nws yog qhov ntau dua los siv cov kav dej tooj liab ua dej rau sab nraud vim tus tooj ntawm cov neeg txawv teb chaws tsis tshua muaj, thiab lub sijhawm kev txhim kho hauv tebchaws txawv teb chaws yog ntev.
Nrog rau kev txhim kho ntawm cov kav hlau hauv tsev stainless hlau, ntau ntau thoob ntiaj teb hom lub hnub qub cov kav dej. Kuj siv cov kav dej stainless hlau. Lub zeem muag ntawm stainless hlau yeeb nkab ntawv thov yuav tsuas yog ua lwm yam thiab dav rau yav tom ntej. Feem ntau ntawm cov yeeb nkab cov tshuab yeeb nkab yuav tsum tso rau hauv Precision stainless hlau raj ua tshuab sai li sai tau mus rau hauv kev lag luam, thiab Hangao Tech (Seko Machinery) yuav yog koj tus khub txhim khu kev qha.
