Puas yog alloy c22 sib nqus?
Kev tswj cov pa phem, kev kho khib nyiab thiab kev tsim hluav taws xob
Vim muaj kuab paug los ntawm kev kub hnyiab ntawm fossil fuels, ntau lub teb chaws nruj me ntsis tswj cov sulfur dioxide emissions. Qhov no yog ib qho kev txhawj xeeb tshwj xeeb rau cov chaw siv hluav taws xob hluav taws xob. Flue gas desulfurization siv cov tshuaj tiv thaiv kom tshem tawm cov sulfur dioxide los ntawm cov pa hluav taws xob uas tsim los ntawm cov txheej txheem combustion. Qhov no zoo heev ntawm kev txwv SO2 emissions.
Ntau cov tswv yim tau tsim, feem ntau yog cov ntub dej txhuam siv seawater los yog alkaline sorbent slurry (feem ntau yog txiv qaub lossis limestone); thiab qhuav scrubbing siv tib alkaline sorbent. Txawm hais tias xaiv txoj kev twg, flue gas desulfurization cuam tshuam nrog kev siv cov khoom corrosive heev. Yog li ntawd, alloy C22 yog lub ntuj xaiv thaum nws los txog rau kev tsim khoom.
Alloy C22 yog cov khoom siv zoo heev rau kev siv hauv cov thawv uas muaj cov khib nyiab corrosive. Vim nws tsis kam mus rau huab cua kub thiab corrosion, nws kuj yog siv los ua cov txheej tiv thaiv rau boiler raj thiab dej phab ntsa hauv cov hluav taws xob hluav taws xob hluav taws xob. Qhov no yog qhov tseem ceeb tshwj xeeb vim tias sulfur dioxide, sulfur trioxide thiab dej vapor uas tsim los ntawm kev sib xyaw ntawm fossil fuels condense ntawm qhov kub thiab txias los tsim sulfuric acid thiab sulfurous acid.
Cov alloy tau pom zoo los ntawm ASME Boiler thiab Pressure Vessel Code, Tshooj VIII, Division 1, siv rau hauv kev tsim cov hlab ntsha siab thiab cov khoom siv rau kev siv kub txog 677 degree.
Pulp thiab ntawv ua
Pulp thiab ntawv ua yog lwm qhov chaw uas cov hlau yuav tsum tau ua haujlwm nyob rau hauv ib puag ncig corrosive heev. Txawm li cas los xij, tsis hais txog kev siv tshuab, txhua lub tshuab pulp lossis ntawv zeb siv cov xov xwm hnyav xws li tshuaj dawb, acids thiab ntsev, thiab qee cov txheej txheem ntawm cov txheej txheem tsim muaj qhov kub thiab txias. Yog li ntawd, high-strength alloys yog xav tau los tiv thaiv cov khoom ntawm deforming, pitting, cracking los yog corrosion rau ntev li ntev tau. INCONEL Alloy C22 yog ib qho kev xaiv nrov vim nws tsis kam mus rau ntau yam corrosive media hauv cov xwm txheej kub heev.
Kev siv dej hiav txwv
Cov dej corrosion ntawm Alloy C22 yog nws lub peev xwm overriding thaum siv hlau qhov chaw hauv marine ib puag ncig. Vim nws cov ntsiab lus ntsev siab, dej hiav txwv corrodes hlau tsib zaug sai dua li dej tshiab. Txij li cov khoom siv hauv nkoj tsim, sab nrauv thiab lwm yam kev siv dej hiav txwv raug nthuav tawm, thiab tej zaum yuav raug raus hauv dej hiav txwv thoob plaws hauv lawv lub neej, nws tseem ceeb heev uas yuav tau xaiv cov khoom uas tuaj yeem tiv thaiv kev puas tsuaj ntev li ntev tau. Cheebtsam tsis ua hauj lwm nce nqi txij nkawm, cuam tshuam kev nyab xeeb thiab ua rau lub neej ua haujlwm luv ntawm cov nkoj thiab cov chaw. Cov txiaj ntsig ntawm dej corrosion tuaj yeem ua tau sai thiab hnyav.
Nickel alloys feem ntau yog cov khoom siv rau kev siv marine thiab offshore. INCONEL Alloy C22 tshwj xeeb yog qhov kev xaiv zoo tshaj plaws los ntawm marine engineers vim nws zoo heev tiv thaiv dej hiav txwv yaig nyob rau hauv ob qho tib si nyob ruaj ruaj thiab ntws. Cov kav dej thiab cov cua kub sib txawv tsuas yog ob qho ntawm nws siv hauv kev lag luam offshore roj thiab roj.
Kev siv tshuaj thiab petrochemical
Txij li Alloy C22 tsis tshua muaj kev tiv thaiv los ntawm ntau yam corrosive xov xwm, nws muaj nuj nqis heev hauv cov tshuaj thiab petrochemical ua teb. Cov kav dej lossis cov hlab ntsha ua los ntawm Alloy C22 muaj peev xwm ua kom muaj kev nyab xeeb los yog xa cov tshuaj hnyav thaum tseem nyob ruaj khov thiab tiv thaiv corrosion, pitting thiab tawg nyob rau hauv qhov kub thiab txias thiab / los yog corrosive ib puag ncig. Raws li austenitic alloy uas muaj tsawg dua 3% hlau, Alloy C22 kuj tseem tiv taus cov creep (deformation los ntawm kev rov ua dua txhua yam kev ntxhov siab ntawm qhov kub thiab txias) thiab embrittlement.
Cov txiaj ntsig ntawm INCONEL Alloy C22 hauv ib puag ncig zoo li pom tseeb. Nws muaj lub neej ua haujlwm ntev dua, nws yooj yim dua los ntxuav vim tsis muaj pitting thiab tawg, yuav tsum tau muaj kev saib xyuas tsawg dua thiab raug nqi ntau dua. Siv Alloy C22 los tsim cov hlab ntsha, cov khoom siv thiab cov kav dej kuj tseem muaj kev tiv thaiv ntau heev ntawm cov dej xau, kev sib kis thiab lwm yam uas yuav ua rau muaj kev phom sij. Nyob rau hauv xws li ib tug muaj kev pheej hmoo, high-pressure daim ntawv thov, Alloy 22 lub superior corrosion qualities thiab kub kub kuj teem nws sib nrug, txawm piv rau lwm yam nickel alloys.
