Marine ib puag ncig: rau seawater piping systems, heat exchangers, thiab condenser raj.
Kev ua tshuaj lom neeg: rau kev tuav cov tshuaj corrosive heev.
Roj thiab roj: tshwj xeeb tshaj yog nyob rau hauv offshore drilling thiab refineries.
Aerospace: rau siv nyob rau hauv siab - kub, siab - ib puag ncig kev nyuaj siab.
Qhov txias - kos seamless raj tsim kom ntseeg tau tias cov khoom siv kho tshuab zoo tshaj plaws thiab qhov chaw tiav, ua rau nws zoo tagnrho rau cov ntawv thov no.
3. Dab tsi yog cov cuab yeej cuab tam ntawm Monel UNS N04400 txias- kos seamless raj?
Teb:
Monel UNS N04400 txias-kos seamless raj nthuav tawm cov khoom siv kho tshuab zoo heev, suav nrog:
Tensile zog: Feem ntau nyob ib ncig ntawm 70,000 psi (485 MPa) lossis siab dua.
Yield zog: Kwv yees li 30,000 psi (205 MPa).
Elongation: 40% yam tsawg kawg nkaus, uas txhais tau hais tias cov hlau tuaj yeem raug deformation tseem ceeb ua ntej tawg, ua rau nws muaj zog heev.
Hardness: Nws feem ntau muaj Brinell hardness ntawm ib ncig ntawm 150, uas muab kev tiv thaiv zoo rau hnav thiab puas.
Cov khoom no ua rau nws zoo - haum rau siab - siab thiab siab - ib puag ncig kev ntxhov siab.
4. Cov txheej txheem ua kom txias li cas rau kev ua haujlwm ntawm Monel raj?
Teb:
Cov txheej txheem txias -kos tau zoo txhim kho kev ua tau zoo ntawm Monel UNS N04400 raj hauv ntau txoj hauv kev:
Txhim kho qhov chaw tiav: Kev kos duab txias ua kom lub ntsej muag zoo nkauj, ua rau nws zoo tagnrho rau cov ntawv thov uas xav tau kev huv siab lossis qhov tseeb.
Ua kom muaj zog: Cov txheej txheem ntxiv dag zog rau cov khoom siv los ntawm elongating cov nplej thiab ua kom zoo dua cov qauv, txhim kho tensile thiab yield zog.
Dimensional raug: Txias- cov raj kos tau nruj dua, uas yog qhov tseem ceeb rau cov ntawv thov uas xav tau qhov ntev.
Txhim kho qhov tawv tawv: Cov duab txias ua rau muaj qhov tawv tawv dua piv rau cov khoom kub- dov, ua rau lub raj zoo dua hnav.
5. Dab tsi yog qhov kev tiv thaiv corrosion ntawm Monel UNS N04400 txias -kos seamless raj?
Teb:
Monel UNS N04400 txias-kos seamless hlab yog tiv taus corrosion nyob rau hauv ntau qhov chaw, tshwj xeeb tshaj yog nyob rau hauv:
Seawater: Nws yog resistant rau corrosion nyob rau hauv seawater, ua rau nws zoo tagnrho rau marine daim ntaub ntawv xws li shipbuilding thiab offshore drilling.
Acid thiab alkaline ib puag ncig: Cov hlau ua pov thawj tsis kam rau hydrochloric thiab sulfuric acid, ua rau nws tsim nyog rau kev ua tshuaj.
Kev kub siab - ib puag ncig kub: Monel kuj ua tau zoo ntawm qhov kub siab, txog li 1,000℃F (538 degree), qhov ntau lwm cov ntaub ntawv yuav ua tsis tau vim corrosion.
Zuag qhia tag nrho, Monel UNS N04400 muaj kev tiv thaiv zoo rau ob qho tib si hauv cheeb tsam thiab dav dav, nrog rau kev ntxhov siab corrosion tawg hauv dej hiav txwv.
