Cov khoom tseem ceeb ntawm Rolled Finned Stainless Steel Tubes
Cov ntaub ntawv tseem ceeb rau dov finned stainless hlau raj muaj xws li 304, 316L, thiab 321 stainless hlau qib, nrog 304 thiab 316L yog cov feem ntau siv.
Cov ntaub ntawv no yog qhov kev xaiv zoo tshaj plaws rau cov khoom siv hluav taws xob sib pauv vim lawv cov kev tiv thaiv corrosion zoo heev, kub tsis kam, thiab lub zog txhua yam.
1.304 Stainless Steel: General -cov khoom siv tiv thaiv corrosion{2}}Cov. Muaj 18% chromium thiab 8% npib tsib xee, muaj kev tiv thaiv zoo heev rau oxidation thiab dav corrosion.
Haum rau qhov kub thiab txias tsawg dua los yog sib npaug li 600℃thiab ib puag ncig uas tsis muaj zog corrosive lossis tsis yog -corrosive media, xws li huab cua, dej, thiab chav.
Tus nqi qis, nws yog qhov kev xaiv tseem ceeb rau kev siv dav dav - lub hom phiaj qhov txhab - cov hlab finned, dav siv hauv kev ua zaub mov, tshuab cua txias, thiab lwm yam.
2. 316L Stainless Hlau: Rau qhov chaw muaj corrosive heev. Nrog rau qhov sib ntxiv ntawm 2% -3% molybdenum rau 304, nws tsis kam mus rau chloride ion pitting thiab crevice corrosion yog qhov zoo tuaj.
Nws tuaj yeem tiv taus cov xov xwm corrosive xws li dej hiav txwv, dej khib nyiab, thiab cov kua qaub / alkali daws, nrog rau qhov kub siab tshaj plaws ntawm 800 degree.
Dav siv nyob rau hauv hnyav ib puag ncig xws li marine engineering, tshuaj nroj tsuag, thiab chaw nres tsheb tshav kub ntawm ntug dej hiav txwv.
3.321 Stainless Hlau: Zoo heev -Tsuas Kub Stability. Titanium yog ntxiv rau stabilize cov qauv carbon thiab tiv thaiv intergranular corrosion ntawm kub kub.
Nws nthuav tawm zoo heev -kub tsis kam, tso cai rau lub sijhawm ntev - ua haujlwm tsawg dua lossis sib npaug li 900 degree, ua rau nws tsim nyog rau kev siv metallurgical thiab fais fab xws li boiler flue gas thiab siab -kub cua kub.
