Qhov sib txawv ntawm 254 SMO thiab 316L Stainless Hlau Yeeb Nkab
Ntau tus neeg yuav khoom sib piv 254 SMO yeeb nkab nrog 316L stainless hlau yeeb nkab ua ntej yuav khoom.
Txawm hais tias ob leeg yog cov tsev neeg stainless hlau, lawv cov qib kev ua tau zoo sib txawv heev.
Corrosion Resistance
254 SMO muaj kev tiv thaiv corrosion zoo dua li 316L, tshwj xeeb tshaj yog nyob rau hauv seawater thiab chloride-cov ntawv hnyav.
Lub zog
254 SMO stainless hlau yeeb nkab muaj zog dua txhua yam, tso cai rau cov phab ntsa nyias nyias thaum tuav cov kav ntev.
Nqi
Tus nqi ntawm 254 SMO yeeb nkab yog siab dua vim nws cov ntsiab lus nickel thiab molybdenum.
Txawm li cas los xij, lub neej ntev dua feem ntau txo cov nqi tag nrho ntawm qhov project.
Daim Ntawv Thov Ntau
316L ua haujlwm zoo rau kev siv dav dav.
254 SMO yog qhov nyiam rau kev ua haujlwm sab nrauv, dej hiav txwv, thiab tshuaj lom neeg.
Qhov tseem ceeb ntawm cov qauv siv thiab kev lag luam siv
Marine & Offshore Platforms:Siv dav rau subsea ballast dej systems, hluav taws kub-txoj kev thaiv lub voj voog, thiab cov kab tawm sab nraud.
Pulp & Paper Processing:Resistant cov tshuaj chlorine dioxide bleaching neeg ua phem nyob rau hauv niaj hnub ntawv zeb digesters.
Desalination Facilities:Ua lub luag haujlwm tseem ceeb hauv kev thauj mus los rau siab -siab rov qab osmosis units tuav cov dej hiav txwv nyoos.
Flue Gas Desulfurization (FGD):Withstands cov kua qaub heev scrubbers siv nyob rau hauv lub zog tsim los ntxuav cov pa roj emissions volatile.
Qhov zoo ntawm Kev Siv 254 SMO Yeeb Nkab
Exceptional Pitting Resistance
Tus nqi PREN ntawm 254 SMO yog qhov siab heev, ua rau nws tiv taus qhov chaw xeb.
Lub neej ua haujlwm ntev
Cov phiaj xwm siv 254 SMO stainless hlau kav feem ntau muaj kev hloov qis dua.
Kev ua tau zoo ntawm Fabrication
Cov khoom tuaj yeem welded thiab fabricated siv cov txheej txheem stainless hlau.
Txo cov nqi kho mob
Txawm hais tias cov nqi pib yog siab dua, cov nuj nqis mus sij hawm ntev - qis dua.
Kev ntseeg tau zoo dua
Cov chaw lag luam nyiam cov khoom siv txhim khu kev qha uas txo qis kev pheej hmoo kaw.
FAQ
Puas yog 254 SMO zoo dua Duplex stainless hlau?
