Xaiv Qib 304 vs . 316 rau Stainless Hlau Nipples
Stainless hlau yeeb nkab txiv mis pab nyob rau hauv ib puag ncig yuav tsum tau corrosion kuj. Ob qib khoom tseem ceeb yog 304 thiab 316. A ss 304 txiv mis muaj chromium thiab npib tsib xee. Nws tiv taus oxidation nyob rau hauv cov qauv dej, huab cua, thiab qhuav tshuaj siv. Nws yog tus nqi - tus qauv zoo rau cov kav dej hauv tsev thiab kev ua zaub mov.
Rau ib puag ncig hnyav, npt stainless hlau txiv mis ua los ntawm Qib 316 yog qhov tsim nyog. Qib 316 suav nrog molybdenum. Cov khoom no ua rau muaj kev tiv thaiv chloride corrosion, ua rau nws tsim nyog rau thaj chaw marine lossis tshuaj nroj tsuag. Kev siv qib tsis raug tuaj yeem ua rau pitting thiab kev ua haujlwm tsis zoo.
Raws li Tuam Tshoj chaw tsim khoom, peb tsim cov txiv mis hauv ob qib. Piv txwv li, 1 nti stainless hlau yeeb nkab lub txiv mis muaj nyob rau hauv Teem 40 lossis Teem 80 phab ntsa thicknesses. Peb khij txhua daim nrog cov khoom siv qib thiab cov xov tooj cua sov rau traceability. Peb lub Hoobkas ua cov tshuaj ntsuam xyuas kom paub meej tias cov ntsiab lus nickel thiab molybdenum ua tau raws li ASTM A733 specifications.
