1 Khoom Description
Thaum lub thickness ntawm lub cladding phaj (SUS304) yog kuj nyias (3 hli nyob rau hauv daim ntawv), tus nqi ntawm tus nqi yuav tsum siab tshaj qhov zoo tshaj tus nqi xam theoretical; Thaum lub thickness ntawm ob lub phaj (SUS304) kuj yog tuab (6 hli nyob rau hauv cov ntawv nyeem), tus nqi them yuav tsum yog me ntsis qis dua tus nqi qis dua ntawm kev xam cov theoretical. Hauv kev tsim khoom tiag tiag, rau qhov tawg cladding ntawm SUS304 thiab Q345R, thaum lub phaj cladding yog nyias (3mm hauv cov ntawv), yog tias qhov kev sib txuas zoo ntawm cov phaj cladding yog qhov tseem ceeb, cov nyhuv yog qhov zoo heev thaum tus nqi thickness yog 30mm; Yog tias tus nqi tsim khoom yog qhov tseem ceeb, tus nqi them thickness tuaj yeem yog 15 hli, yog li kev sib txuas zoo ntawm cov phaj cladding tau txais kuj ua tau raws li tus qauv yuav tsum tau ua: thaum lub phaj cladding yog tuab (6 hli hauv cov ntawv), lub zog sib txuas yuav zoo dua thaum tus nqi thickness yog 25mm.
2 Qhov zoo thiab qhov tsis zoo ntawm kev tawg vuam
Raws li kev siv thev naus laus zis saum npoo av, SS304 Stainless Hlau Clad Steel Phaj raws li cov chav kawm ntawm cov khoom siv engineering ntog muaj ntau yam ntxwv, suav nrog cov txiaj ntsig hauv qab no.
(1) Cov txheej txheem vuam tawg muaj qhov yuav tsum tau qis rau cov khoom siv kho vajtse. Tsuas yog cov khoom siv hlau, cov khoom tawg vuam tawg, thiab qhov chaw tsim nyog yog xav tau rau kev tawg vuam ntau lawm ntawm cov phaj sib xyaw, tsis muaj cov cuab yeej meej heev thiab kev saib xyuas tom qab.
(2) Cov txheej txheem vuam tawg tsis yog qhov nyuaj, thiab cov neeg ua haujlwm cuam tshuam tuaj yeem nqa lawv cov haujlwm tsuas yog tom qab kev cob qhia yooj yim tom qab ua tiav kev tswj hwm kev nyab xeeb.
(3) Kev xaiv cov khoom siv tsis yog nruj, thiab nws tuaj yeem xaiv tau raws li qhov kev tso cai ntawm kev siv tshuab vuam tawg.
(4) Kev tsim cov nplais ntawm cov hlau nplaum tawg tuaj yeem loj heev, thiab kev siv tus nqi ntawm cov khoom xws li cov ntaub ntawv thiab lub sijhawm yog siab heev.
(5) Lub zog sib txuas ntawm cov khoom tawg welded yog siab heev, thiab txawm tias nws raug rau ntau hom kev ua haujlwm tom qab, yuav tsis muaj kev tawg lossis delamination uas yuav cuam tshuam rau qhov zoo ntawm cov phaj sib xyaw.
(6) Kev tawg vuam tuaj yeem ua ke nrog cov txheej txheem ua haujlwm ib txwm muaj. Tom qab ua tiav cov paib tawg, cov duab ntawm daim hlau tuaj yeem hloov pauv yam tsis muaj kev cuam tshuam rau qhov zoo ntawm daim hlau clad kom hloov mus rau cov ntawv thov kev lag luam.
(7) Tom qab tawg vuam, cov ntaub ntawv raw thiab cov phaj sib xyaw yuav ua kom tawv, uas yuav pab txhim kho corrosion thiab hnav tsis kam ntawm cov ntaub ntawv rau qee qhov, yog li txhim kho lub zog ntawm cov ntaub ntawv.
(8) Kev tsim cov hlau-clad daim hlau los ntawm kev tawg vuam tuaj yeem tsis yog tsuas yog cov txheej txheem sib xyaw xwb tab sis kuj tsis txwv rau qee yam duab thiab style. Ntxiv rau kev tsim cov phaj sib xyaw ua ke, nws tseem tuaj yeem tsim cov kav dej sib xyaw, cov khoom sib xyaw, thiab lwm yam.
Nrog rau txoj kev loj hlob ntawm tawg vuam tshuab, SS304 Stainless Hlau Clad Steel Phaj
(9) cov khoom tsim tawm tsis txwv rau cov khoom siv hlau sib xyaw. Los ntawm kev tswj cov txheej txheem tsis, qee cov nonmetals, xws li ceramics, kuj tuaj yeem tsim cov ntaub ntawv sib xyaw nrog cov hlau los ntawm kev sib tsoo tawg, nthuav dav daim ntawv thov ntawm cov txheej txheem.
3Kev tshawb fawb txheej txheem ntawm tawg vuam txheej txheem
Muaj ntau yam uas cuam tshuam rau qhov zoo ntawm kev tawg vuam. Nyob rau hauv cov txheej txheem kev sib tsoo tsoos, hom kev tawg, txoj kev tawg, txoj kev pib, cov khoom siv thiab qhov ntev ntawm clad phaj thiab phaj phaj, qhov kev ncua deb ntawm clad phaj thiab lub hauv paus phaj, thiab hom ntawm lub hauv paus tuaj yeem txhua yam cuam tshuam rau kev sib raug zoo ntawm clad phaj. Rau kev tshawb fawb ntawm cov txheej txheem vuam tawg, cov neeg ua ntej tau ua haujlwm ntau heev. Nrog rau kev xav tau ntawm kev lag luam niaj hnub no rau kev sib tsoo vuam sib xyaw daim hlau, qhov kev tshawb fawb ntawm cov txheej txheem vuam tawg kuj tseem muaj ntau zuj zus. Cov txheej txheem pib tuaj yeem muab faib ua plaub yam hauv qab no: qhov chaw taw tes pib, peach zoo li ntug taw tes pib, thiab "T" hom linear yoj pib. Daim duab 14 qhia txog plaub txoj kev pib sib txawv, thiab nws tuaj yeem pom los ntawm daim duab uas cov nthwv dej pem hauv ntej tau txais los ntawm cov txheej txheem pib sib txawv kuj tseem yog qhov sib txawv ntawm qhov pib peach zoo li tus ntug taw tes pib T "hom pib linear yoj pib daim duab 1.4 Cov kev pib sib txawv rau kev tawg vuam. .
Fig. 1.4 Cov txheej txheem pib sib txawv ntawm kev tawg vuam
(1) Center point pib: Txoj kev no muaj qhov zoo ntawm kev ua haujlwm yooj yim. Nws tuaj yeem muaj qhov sib nqus loj heev deflection interface waveform nyob rau hauv nruab nrab ntawm lub phaj cladding, uas tuaj yeem ua tau zoo sib xws thiab sib faib ntawm qhov sib cuam tshuam. Txawm li cas los xij, qhov tsis zoo ntawm txoj kev no yog qhov pom tseeb heev: vim tias qhov pib ntawm lub hauv paus ntsiab lus, muaj ib qho kev sib tsoo ntsug nrog xoom kev sib tsoo lub kaum sab xis nyob ze ntawm lub hauv paus pib taw tes, qhov twg tsis muaj tiam ntawm kev sib cuam tshuam thiab tsis muaj kev sib txuas. Qhov loj ntawm cov yoj tsis pub muaj feem cuam tshuam nrog xws li cov thickness ntawm cov phaj cladding, qhov loj ntawm qhov tawg, qhov loj ratio R ntawm cladding phaj, thiab lub detonation tshaj tawm ntawm lub explosive. Qhov loj dua qhov tuab ntawm cov phaj cladding, qhov loj dua qhov tsis muaj nthwv dej. Tus kheej acceleration txheej txheem ntawm qis detonation tshaj tawm explosive los ntawm detonator pib mus rau ruaj khov detonation yog ntev, yog li qhov ntau ntawm nthwv dej dawb cheeb tsam yog loj. Rau qhov chaw nrog qhov nruab nrab, xws li flanges, nws yog qhov tsim nyog los siv qhov chaw nruab nrab ntawm txoj kev detonation.
Peach zoo li tus ntug taw tes pib: txoj kev no yog coj cov pib taw tes tawm ntawm lub phaj cladding, kom tsis txhob muaj kev sib xyaw ua ke los ntawm kev sib tsoo ntsug ntawm lub phaj cladding thiab lub substrate nyob rau hauv lub hauv paus cheeb tsam nyob rau hauv lub hauv paus pib txoj kev. Txoj kev no yog qhov yooj yim thiab tsim nyog rau kev tawg vuam ntawm cov voj voog clad daim hlau. Daim duab 1.5 qhia tau hais tias cov phaj tiav tiav ua los ntawm peach zoo li tus ntug taw tes pib Daim duab 1.5 Cov phaj tiav tiav ua tiav los ntawm peach zoo li tus ntug taw tes pib.

(3) "T" hom kev pib: txoj kev no yog ntxiv ib txoj hlua ntawm qhov siab tshaj plaws detonation explosive los yog detonating qaum rau qhov pib kawg kom txhim kho lub detonation nthwv dej pem hauv ntej thiab txo qhov curvature ntawm lub wavelet pem hauv ntej. Rau cov duab plaub cladding daim hlau nrog me me dav, txoj kev no yog tsim rau tawg vuam.
Linear nthwv dej pib: txoj kev no tuaj yeem ua rau tag nrho cov ntsiab lus ntawm qhov pib kawg detonate tib lub sijhawm, uas tsis tsuas yog txhim kho cov vuam zoo ntawm qhov pib kawg, tab sis kuj muab cov kev mob zoo dua rau kev txav ntawm cov phaj clad thiab kev sib tsoo nrog cov substrate. Rau cov duab plaub sib txuas nrog thaj tsam loj, qhov tawg vuam nrog txoj kev pib no tuaj yeem tau txais txiaj ntsig zoo dua. Ib qho kev pib tshwj xeeb yuav tsum tau ua kom muaj cov kab hluav taws xob tawm, uas yog, lub tshuab hluav taws xob linear yoj raws li qhia hauv daim duab 1.6. Nws tuaj yeem ua tau los ntawm kev sib npaug ntawm cov khoom sib npaug ntawm daim duab peb sab (raws li qhia hauv daim duab 16 (a)), lossis los ntawm kev sib txuas ob lub foob pob nrog sib txawv detonation tshaj tawm (raws li qhia hauv daim duab 1.6 (b))
