Tus09crrisbLub raj, tseem hu ua ND Alloy steel yeeb nkab, yog qhov tsis tshua muaj kev siv hluav taws xob, thiab evaporators kev ua haujlwm hauv siab-}}}} sulfur fluue gas ib puag ncig.
Nws zoo tiv thaiv sulfuric acid lwg point corrosion thiab acid corrosion hauv cov nroj tsuag hluav taws xob, ua kom muaj hluav taws xob, thiab petrochemical Industries.
Qhov no nd tsawg {- Alloy allocural cov qauv hlau tau tsim tshwj xeeb rau cov sulphuric acid lwg dew point tej yam kev mob. Nws yog tsim kev siv ultra {2} high- fais fab hluav taws xob tshuab hluav taws xob, ua kom muaj kev sib tw siab thiab ruaj khov.
Thaum lub sijhawm ua haujlwm, cov ntaub ntawv Alloy Ib Txheej Txheem Compliched Passivation Txheej Txheem Nrog Chromium (CU), Txhob), Txhob), thiab Titanium (Ti). Qhov no cov yeeb yaj kiab tiv thaiv tuab heev tau txhim kho corrosion tsis kam thiab ua kom ntev- teb turability.
Piv rau cov hlau uas muaj cov roj carbon hlau, corten hlau, lossis oxidation ua rau cov khoom siv acidic thiab cov kua roj flu.
Cov Nta Tseem Ceeb
Zoo heev rau cov sulfuric acid lwg point corrosion (hauv qab no 200 degree).
Kev ua haujlwm zoo dua piv rau cov thawv hlau thiab Corten Hlau.
Cov Txheej Tiv Thaiv Tsis Muaj Zog Oxide vim CR-CU-SB synergy.
Zoo weldability yam tsis muaj kev xav tau rau preheating lossis post - weld kev kho cua sov.
Lub neej ntev kev pabcuam lub neej thiab tus nqi -}}}}} Xaiv lwm txoj hauv kev rau cov hlau tsis muaj txiaj ntsig.
