1. Dab tsi yog cov qauv ntawm Monel hlau 400 alloy composite yeeb nkab, thiab ua li cas nws cov khoom ua haujlwm ua haujlwm ua ke?
Monel hlau 400 alloy composite cov yeeb nkab feem ntau muaj cov txheej tseem ceeb thiab txheej cladding. Cov txheej tseem ceeb, feem ntau ua los ntawm cov roj carbon steel lossis qis - cov khoom siv hluav taws xob, ua kom cov yeeb nkab muaj zog, ua kom muaj kev kub siab thiab cov neeg kho tshuab thauj khoom. Lub cladding txheej, muaj ntawm Monel 400 alloy (a nickel- tooj liab alloy nrog 63-70% NI
Cov khoom siv no ua haujlwm hauv kev sib npaug kom sib npaug thiab raug nqi. Cov txheej txheem tseem ceeb txo cov ntaub ntawv cov nqi piv rau cov khoom monic 400 yeeb thaum tswj cov qauv kev ncaj ncees txaus. Lub Monel 400 cladding txheej, nrog nws zoo corrosion tsis kam, tiv thaiv cov yeeb nkab los ntawm kev ua kua dej los ntawm cov dej hiav txwv corrosive, acids, thiab alkalis. Txoj kev sib raug zoo ntawm ob txheej yog qhov tseem ceeb -} Txoj kev sib koom ua ke, yob, kev sib koom ua ke, nws ua rau kev siv hluav taws xob sib hloov thiab tiv thaiv delamination raws li kev ua haujlwm. Cov qauv no ua rau cov yeeb nkab uas haum rau cov ntawv thov uas ob leeg tiv thaiv thiab siab zog yog qhov yuav tsum tau ua.
2. Yuav ua li cas cov txheej txheem tsim kev tsim qauv los tsim monel hlau 400 alloy composite yeeb nkab, thiab dab tsi yog lawv qhov zoo?
Ob peb cov txheej txheem tsim tau yog ua haujlwm los tsim cov monel hlau 400 alloy composite yeeb nkab, txhua tus muaj cov txiaj ntsig zoo. Cov cladding tawg yog ib txoj kev nquag: nws siv cov tshuaj tawg kom tau nyiaj rau Monel 400 cladding rau cov khoom tseem ceeb. Cov txheej txheem no tsim muaj zog metallurgical bond nrog lub zog zoo, txawm tias rau cov duab zoo, thiab ua haujlwm zoo rau tuab {4} {walled kav dej.
Dov tsev sib tham, lwm cov txheej txheem, koom nrog dhau cov tub ntxhais thiab cov khoom siv cladding los ntawm cov mills ntawm cov mills rau lawv ua ke. Nws muab cov kev sib raug zoo thiab kev sib txuas lus zoo heev, ua rau nws haum rau nyias {{1} {{{2} nplai ntau lawm.
Weld Cladding, qhov twg Monel 400 tau muab tso rau hauv vuam cov txheej txheem xws li kev kho cov kav dej, ib yam li kev tsim cov kav dej uas muaj varying cladding thicknesses.
Txhua txoj kev ua kom ntseeg tau cov yeeb nkab composite khaws cov txiv neej 400 thiab lub zog ntawm lub zog ntawm cov tub ntxhais, thaum ua tau zoo nqi thiab ua tau zoo rau cov kev siv tshwj xeeb.
3. Yuav ua li cas lub corrosion resistance ntawm monel hlau 400 alloy composite yeeb nkab sib piv rau cov khoom monel 400 yeeb thiab lwm yam kav dej?
Monel hlau 400 alloy composite yeeb nkab ua yeeb yam corrosion tsis kam piv rau cov khoom mij 400 yeeb nyob hauv ib puag ncig ib puag ncig, ua tsaug rau nws cov monel 400 cladding txheej. Lub Cladding ua raws li txoj kev thaiv, tiv thaiv cov tub ntxhais los ntawm kev tawm tsam ntawm dej hiav txwv, hydroflluoric acid, ib yam li cov khoom monic 400 yeeb.
Piv rau composite pipes nrog lwm cov ntaub ntawv cladding (piv txwv, stainless hlau), monel 400 composite kav kev muab cov chaw tshwj xeeb. Piv txwv li, lawv outperform stainless hlau {}} clad kav dej hauv hydrofric acid thiab sulfuric acid thiab sulfuric acid thiab sulfuric acid thiab sulfuric acid thiab sulfuric acid thiab sulfuric acid thiab sulfuric acid thiab sulfuric acid thiab sulfuric acid thiab sulfuric acid thiab sulfuric acid thiab sulfuric acid thiab sulfuric acid thiab sulfuric acid thiab sulfuric acid thiab sulfuric acid thiab sulfuric acid thiab sulfuric acid thiab sulfuric acid Lawv kuj tiv thaiv pitting thiab crevice corrosion hauv qab ntsev zoo dua li ntau cov qauv stainless hlau.
Cov ntsiab lus tseem ceeb yog Monel 400 Composite kav ua kom tiav qhov kev ua kom zoo dua li cov khoom qis dua monel 400 kav dej, raws li lawv siv tsawg dua ntawm cov kim. Txawm li cas los xij, cov corrosion tsis kam nyob ntawm cladding's confarity-, tawg, pinholes) tuaj yeem nthuav tawm cov tub ntxhais, ua rau galvanic corrosion. Yog li, tsim nyog installation thiab kev txij nkawm yog qhov tseem ceeb heev los khaws cia kev ua tau zoo.
4. Dab tsi yog qhov kev txiav txim siab tseem ceeb rau kev txhim kho thiab koom nrog Monel Hlau 400 Alloy Composite Yeeb Nkab?
Txhim kho thiab koom nrog Monel hlau 400 alloy composite cov yeeb nkab yuav tsum tau ua tib zoo saib xyuas cov cladding txoj kev ntseeg siab thiab xyuas kom meej meej kev ua haujlwm. Thaum txiav cov yeeb nkab, cov cuab yeej yuav tsum yog tus ntse kom tsis txhob ua rau kev puas tsuaj rau cladding; Cov Abrasive txiav abrasive yuav tsum zam kom tiv thaiv kev ua paug ntawm cladding nto.
Kev Koom Tes Nrog Kev Siv Vuam, Flanging, thiab Cougling. Rau vuam, txheej cladding yuav tsum tau npaj kom zoo- ... {{... {... {12}- 7). Kev ua vuam yuav tsum txo cov lus tawm thaum tshav kub kom tiv thaiv dilution ntawm cladding nrog cov ntsiab lus tseem ceeb. Tom qab Weld Tu (piv txwv li, pickling) yog feem ntau tsim nyog los tshem cov kub-cuam tshuam oxides.
Flanged kev sib txuas yuav tsum muaj Gaskets tau sib xws nrog ob qho nruab nrab ntawm cov nruab nrab thiab cov monel 400 kom tiv thaiv kom tsis txhob muaj cov kua zaub thiab xeb. Kev Coumerning Txhua yam yuav tsum yog tsim kom tsis txhob ua rau cov cladding zoo nkauj thiab muab ib lub foob kaw. Ib qho ntxiv, thaum nruab, cov yeeb nkab yuav tsum tau txais kev txhawb nqa kom tiv thaiv kev ntxhov siab ntau dhau ntawm cov pob qij txha, uas tuaj yeem ua rau cladding Delamination lossis cov kev puas tsuaj.
5. Hauv kev lag luam uas yog Monel hlau 400 alloy composite cov yeeb nkab feem ntau siv, thiab vim li cas?
Monel hlau 400 alloy composite yeeb nkab yog dav siv nyob rau hauv kev lag luam uas corrosion tsis kam thiab nqi- ua hauj lwm zoo. Hauv kev lag luam marine, nws yog siv rau dej hiav txwv thiab tawm cov kab, ntxiv rau hauv cov nroj tsuag desalination. Lub Monel 400 Cladding resistays ntsev cen
Hauv kev lag luam ua lag luam, nws tau ua haujlwm hauv cov kav dej rau thauj cov kua qaub (piv txwv li hydrochloric, hydrofluoric) thiab alkalis. Tus qauv sib dhos cov qauv sib npaug nrog lub peev xwm los lis cov kev ntsuas siab hauv cov tshuaj tiv thaiv tshuaj lom neeg thiab hloov cov tshuab.
Cov roj thiab roj kev lag luam siv nws rau Ntughore Lub Nkoj thiab Downhole tubing, uas nws withstands forrosive kua muaj cov sulfide thiab ntsev. Nws lub zog - {{{2} Tus nqi piv txwv ua rau nws zoo tshaj plaws rau ntev- deb li nram qab.
Hauv lub zog loj, nws yog siv nyob rau hauv dej txias rau ntug dej fais fab nroj tsuag, tiv taus corrosion los ntawm dej hiav txwv lossis dej brackish. Zuag qhia tag nrho, nws cov kev sib xyaw ua ke ntawm kev ua tau zoo thiab pheej yig ua rau nws xaiv qhov kev xaiv zoo tshaj plaws hauv cov haujlwm xav tau no.
