Cov cuab yeej ua kom txias lub voj voog, cov khoom noj tsis tu ncua -kub dej tso tsheb hlau luam thiab qis - cov dej khib nyiab preheating kav txhua qhov muaj cov kab mob chloride ions thiab cov kua qaub tsis muaj zog. Ordinary carbon steel cua sov kav dej yog nquag pitting corrosion thiab nruab nrab to nyob rau hauv xws li me me corrosive ib puag ncig. Nyob rau hauv sib piv, siab - kawg tiv thaiv - corrosion lwm yam xws li titanium kav, fused silica kav thiab tag nrho cov PFA cua sov qhov chaw muaj ntau tshaj kev ua tau zoo redundancy thiab overly procurement nqi, uas yuav ua rau kom tsis tsim nyog kev khiav hauj lwm kev siv nyiaj rau kev lag luam. Raws li molybdenum- hloov kho qib stainless hlau qib, 316 stainless hlau cua sov raj tau dhau los ua cov khoom siv hluav taws xob dav dav tshaj plaws rau cov pa ua haujlwm qis - corrosion ua hauj lwm scenarios. Daim ntawv no piav qhia txog nws cov khoom siv hauv lub cev muaj zog, thaj tsam siv tau meej thiab cov qauv kev xaiv engineering, nrog rau cov lus sib piv kev ua tau zoo tshiab rau plaub cov khoom siv cua sov.
1. Core Performance Advantages ntawm 316 Stainless hlau
Qhov sib txawv ntawm 304 stainless hlau tsis tu ncua, cov khoom ntxiv molybdenum zoo heev ntxiv dag zog rau nws cov tshuaj tiv thaiv chloride-induced crevice corrosion thiab pitting corrosion nyob rau hauv dej brackish ib puag ncig. Thaum lub sij hawm rov ua cua sov thiab cua txias, ib txheej tuab chromium oxide passivation tuaj yeem rov tsim dua tshiab ntawm cov yeeb nkab phab ntsa, ua kom muaj kev ruaj khov los thaiv kev cuam tshuam ntawm corrosive ions.
Nyob rau hauv cov nqe lus ntawm cov neeg kho tshuab kev ua tau zoo thiab ua adaptability, no alloy muaj zoo heev structural nruj thiab thermal qaug zog kuj. Nws tuaj yeem tiv taus ntev -lub sij hawm scouring ntawm cov dej ntws thiab nquag kub dhia tsis tas yuav khoov deformation lossis sealing tsis ua haujlwm, ua kom tsis txhob muaj qhov kub hnyiab ntawm cov kab hluav taws xob sab hauv los ntawm kev nkag mus nruab nrab. Tsis tas li ntawd, kev paub tab txiav, khoov thiab argon arc vuam txheej txheem txhawb kev tsim tshwj xeeb - zoo li tus txheej txheem, uas tuaj yeem hloov kho kom yooj yim rau kev nqaim nqaim, cov qauv tank tsis zoo thiab tsis yog - tus qauv ntawm - qhov yuav tsum tau ua hauv cov kav dej.

3. Muaj qhov tsis xws luag thiab txwv tsis pub siv cov xwm txheej
316 stainless hlau tsis tuaj yeem suav tias yog ib qho khoom siv thoob ntiaj teb los tiv thaiv- corrosion. Ntev - lub sij hawm immersion nyob rau hauv siab - kub concentrated muaj zog acid, muaj zog alkali thiab saturated siab - salinity brine yuav irreversibly ua puas lub nto passivation zaj duab xis, ua rau cov phab ntsa tas mus li thinning thiab zaum kawg to scrapping. Rau cov kev sib xyaw corrosive hnyav no, titanium cua sov raj lossis PFA-cov khoom siv cua sov yog cov kev xaiv hloov tau zoo dua.
Ntxiv mus, nyob rau hauv kev ua hauj lwm nrog siab - ceev stirred khoom hais thiab muaj zog abrasive cuam tshuam, lub passivation zaj duab xis yuav mechanically khawb thiab tsis kho nws tus kheej nyob rau hauv lub sij hawm, accelerating lub zos corrosion tsis ua hauj lwm thiab drastic shortening cov kev pab cuam voj voog ntawm lub cua sov raj.
4. Cov Ntsiab Cai ntawm Kev Xaiv thiab Kev Pom Zoo Kawg
Tau txais txiaj ntsig los ntawm molybdenum- txhim kho cov tshuaj chloride corrosion, ruaj khov cov khoom siv thiab kev ua haujlwm hloov tau yooj yim, 316 stainless hlau cua sov raj ua haujlwm zoo tshaj plaws thiab txhim khu kev qha cua sov rau cov pa me ntsis corrosive circulating dej systems. Hauv kev xaiv hom engineering, yuav tsum tau muab qhov tseem ceeb rau cov khoom no rau cov tshuaj chloride- uas muaj cov kav xa dej, khoom noj khoom haus- qib cua sov thiab ib txwm-kub dej khib nyiab preheating. Thaum qhov nruab nrab ua haujlwm muaj qhov kub thiab txias, muaj zog alkali, siab salinity thiab abrasives, siab - qib tiv thaiv - cov ntaub ntawv corrosion yuav tsum tau hloov ua ntej. Tsuas yog los ntawm kev sib piv cov yam ntxwv ntawm cov khoom siv nrog cov kev ua haujlwm tiag tiag tuaj yeem ua haujlwm ntev - lub sijhawm ua haujlwm nyab xeeb ntawm cov khoom siv cua sov thiab kev tswj hwm tsim nyog ntawm tag nrho cov nqi tsim nyog yuav lav.
