Cov lus piav qhia ntxaws ntxaws ntawm Monel 400 (Monel400, N04400) alloy khoom paub
Monel 400 (N04400) nickel-tooj liab alloy cov khoom siv:
Monel 400 (Monel 400, N04400) yog npib tsib xee-tooj liab alloy nrog thawj-chav corrosion tsis kam mus rau ntau yam kev txo cov xov xwm, thiab kuj muaj qee yam khoom siv kho tshuab. Monel400 muaj qhov tshwj xeeb zoo corrosion kuj tiv thaiv huab cua tsis muaj hydrofluoric acid, nruab nrab thiab alkaline ntsev daws.
Monel 400 yog siv rau uranium refining thiab isotope sib cais nyob rau hauv nuclear roj ntau lawm. Nws yog cov khoom siv txheem rau cov concentration thiab crystallization ntawm ntsev tov, vinyl chloride monomer (VCM) ntau lawm, MDI thiab TDI ntau lawm, thiab roj av refining. Monel 400 kuj tseem siv los tsim cov khoom siv hluav taws xob thiab cov tshuab hluav taws xob ua hluav taws xob hloov hluav taws xob, cov kav dej sheathed thiab platform steel kab siv nyob rau hauv offshore roj thiab roj ntau lawm. Monel 400 alloy tau ntawv pov thawj rau kev siv hauv cov hlab ntsha siab nrog kev ua haujlwm kub ntawm -10 thiab 425 degree (18 thiab 797 degree F).
1. Monel400 alloy muaj zoo corrosion kuj tiv thaiv kev nyuaj siab corrosion tshwm sim los ntawm txhuas ntsiab
2.Monel400 tseem tuav lub zog zoo ntawm qhov kub thiab txias
3.Monel400 (N04400) yog yooj yim rau txheej txheem dua lwm cov ntaub ntawv siab alloy
Certified rau siv nyob rau hauv siab hlab ntsha los ntawm -10 mus rau 425 degree (14 mus rau 797 degree F) raws li VdTÜV Material Sheet No. 263, nrog rau siab tshaj plaws kev pab cuam kub txog li 480 degree (896 degree F) raws li ASME Boiler thiab Pressure Vessel Code).
Corrosion kuj ntawm Monel 400 (N04400) khoom:
Monel 400 (Monel 400, N04400) muaj kev tiv thaiv zoo heev rau cov ntsev nruab nrab thiab alkaline ntsev, yog li nws tau ntev ua cov khoom siv hauv kev tsim cov ntsev. N04400 yog ib qho ntawm ob peb cov ntaub ntawv uas tuaj yeem tiv nrog fluorine, hydrofluoric acid, hydrogen fluoride thiab lawv cov tebchaw. Cov khoom muaj zoo heev tiv thaiv corrosion los ntawm alkaline xov xwm. Nws kuj ua tau zoo heev hauv dej hiav txwv thiab muaj cavitation zoo dua li tooj liab-raws li alloys. Monel400 Monel alloy muaj qhov zoo corrosion tsis kam rau dilute ntxhia acids (xws li sulfuric acid thiab hydrochloric acid) nyob rau hauv qhov tsis muaj cua.
Txij li Monel 400 (Monel 400, N04400) tsis muaj chromium, tus nqi corrosion yuav nce ntau nyob rau hauv oxidizing tej yam kev mob. Txawm hais tias Monel 400 tuaj yeem tiv taus kev ntxhov siab corrosion tawg, kev ntxhov siab tawg tuaj yeem tshwm sim thaum raug mercury-muaj lossis moist hydrofluoric acid vapors. Yog tias siv raws li cov xwm txheej saum toj no, kev ntxhov siab yuav tsum tau ua.
Cov chaw siv ntau yam ntawm Monel 400, Monel 400, thiab N04400 suav nrog:
1. Pub dej thiab chav tshuab hluav taws xob hloov hluav taws xob hauv cov chaw fais fab
2. Brine heaters thiab recompression evaporators nyob rau hauv ntsev nroj tsuag
3. Sulfuric acid thiab hydrofluoric acid alkylation
4. Thaum tshav kub kub exchangers hauv kev lag luam tshuaj
5. Electroplating khoom rau cov ntxhia roj distillation nroj tsuag
6. Splash cheeb tsam hauv ob sab phlu ntawm ntug dej hiav txwv platform
7. Nkoj impellers thiab twj tso kua mis shafts
8. Refineries uas tsim cov roj nuclear
9. Twj thiab li qub ntawm cov kab ntau lawm rau tetrachlorethylene (perchlorethylene) thiab chlorinated plastics
10. Cua sov raj rau monoethanolamine (MEA)
Tsis tas li ntawd, Monel 400, Monel 400, thiab N04400 kuj tseem siv rau hauv cov roj qaub-resistant Cheebtsam rau roj thiab cov khoom siv roj.
