Cov qhab nia xaiv tau
- Hauv cov ntawv thov uas tsis muaj kev tiv thaiv corrosion tsis yog qhov tseem ceeb, 304L stainless hlau yuav raug siv; thaum nws lub zog thiab cov tshuaj chloride tsis zoo rau cov Duplex 2205 stainless hlau, nws yog qhov zoo dua rau cov tshuaj lom neeg ib puag ncig zoo dua -xws li hauv cov khoom siv hluav taws xob los tuav cov dej los yog cov kua dej uas muaj cov tshuaj chloride tsawg.
- Rau cov tshuaj ib puag ncig uas muaj zog acidic media- xws li sulfuric thiab phosphoric acids-904L yog ib qho kev xaiv tsim nyog; Nws yog feem ntau ua haujlwm nyob rau hauv cov khoom siv kua qaub, tshuaj reactors, thiab cov kav dej hauv kev lag luam chiv.
- Hastelloy C276 nthuav tawm tshwj xeeb ua rau muaj zog acids, chlorides, thiab corrosive siab - qhov kub thiab txias ib puag ncig, ua rau nws siv tau lwm txoj hauv kev rau 2205 rau siab - kub daim ntawv thov.
thaj chaw thov
ASTM A789 2205 stainless hlau yeeb nkab haum rau corrosion-cov tshuaj tiv thaiv ib puag ncig, xws li cov txheej txheem kav dej rau kev xa cov tshuaj corrosive-xws li chlorides, acids, thiab alkalis-nrog rau cov cua kub exchanger tubing thiab plhaub hauv cov nroj tsuag tshuaj, tshuaj reactors, dej hiav txwv dej thiab cov chaw kho mob desalin.

FAQ
Q: Puas yog 2205 yeeb nkab yooj yim rau vuam? Nws puas xav tau tom qab-weld kev kho cua sov?
A: Peb cov kav dej tuaj yeem welded siv cov kev sib txuas xws li TIG thiab MIG, thiab yuav tsum tsis muaj kev tshaj tawm -weld heat treatment nyob rau hauv ib txwm ua haujlwm.
Q: Cov yeeb nkab no puas tuaj yeem siv rau hauv dej hiav txwv / chloride ion ib puag ncig?
A: Yog. 2205 duplex stainless hlau muaj tus nqi PREN Ntau dua lossis sib npaug rau 36, pom zoo ua haujlwm zoo rau cov tshuaj chloride ion pitting thiab kev ntxhov siab corrosion tawg, ua rau nws tsim nyog rau seawater desalination, marine engineering, thiab cov kav dej ntawm ntug dej hiav txwv.
Q: Dab tsi yog qhov kam rau ua rau sab nraud thiab phab ntsa thickness?
A: Sab nraud txoj kab uas hla kam rau ua ± 0.05 hli, phab ntsa thickness kam rau ua ± 7.5%, ncaj tsawg dua los yog sib npaug li 0.5 mm / m, haum rau siab - cov ntawv thov xws li kev siv vuam siv hluav taws xob thiab cov khoom siv hluav taws xob sib txuas.
