Cov khoom siv cua txias hauv cov kav dej txias, cov dej kub tsis tu ncua rau kev ua zaub mov thiab cov kav dej ua ntej ua kom tsis muaj zog rau cov dej khib nyiab uas tsis tshua muaj - cov dej khib nyiab tag nrho muaj cov kab mob chloride ions thiab cov tshuaj tsis muaj zog acidic organic. Ordinary carbon steel cua sov raj yuav sai sai tsim pitting corrosion thiab nruab nrab to nyob rau hauv xws li me ntsis corrosive kev khiav hauj lwm ib puag ncig. Hauv qhov sib piv, siab -kawg tiv thaiv- kev tiv thaiv corrosion xws li cov raj ntshiab titanium, fused quartz raj thiab tag nrho -lined PFA cua sov modules muaj kev ua haujlwm ntau dhau thiab cov nqi yuav khoom ntau dhau, uas ua rau muaj kev lag luam tsis tsim nyog rau kev tsim khoom lag luam. Raws li molybdenum- alloy optimized stainless hlau qib, 316 stainless hlau cua sov raj tau dhau los ua cov khoom siv cua sov tshaj plaws rau cov pa roj carbon monoxide tsawg- corrosion ua hauj lwm tej yam kev mob. Daim ntawv no txheeb xyuas nws qhov zoo ntawm cov khoom siv, cov ciam teb kom meej thiab cov qauv kev xaiv engineering, ua ke nrog cov lus sib piv ua tau zoo tshiab ntawm plaub cov khoom siv cua sov.
1. Core Performance Advantages ntawm 316 Stainless hlau
Sib txawv ntawm cov pa 304 stainless hlau, cov khoom molybdenum ntxiv tau zoo heev txhim kho nws cov tshuaj tiv thaiv chloride -induced crevice corrosion thiab pitting corrosion nyob rau hauv cov dej tsis zoo. Thaum lub sij hawm rov ua cua sov thiab cua txias, qhov ntom ntom chromium oxide passivation zaj duab xis tuaj yeem rov tsim dua tshiab ntawm cov phab ntsa sab nrauv, ua kom muaj kev ruaj khov los thaiv cov ions tsis zoo los ntawm kev nkag mus rau hauv lub hauv paus hlau.
Nyob rau hauv cov nqe lus ntawm txhua yam khoom thiab kev ua tau yooj yim, cov alloy no muaj cov yam ntxwv zoo heev rigidity thiab thermal qaug zog tsis kam. Nws tuaj yeem tiv taus ntev -lub sij hawm scouring ntawm ntws tawm thiab nquag hloov pauv kub yam tsis tas yuav khoov deformation lossis sealing tsis ua haujlwm, tiv thaiv qhov kub hnyiab ntawm cov hluav taws xob sab hauv hluav taws xob los ntawm cov kua infiltration. Tsis tas li ntawd, paub tab txiav, khoov thiab argon arc vuam thev naus laus zis txhawb kev kho tshwj xeeb- zoo li tus qauv, uas tuaj yeem hloov kho kom yooj yim rau kev nqaim nqaim, lub cev tsis tu ncua ntawm lub tank thiab tsis yog- tus qauv ntawm -site pipeline layout yuav tsum.

表格
| Cov khoom cua sov | Chloride Corrosion Resistance | Ntev -Lub Sij Hawm Thermal Stability | Dej Erosion Resistance | Routine Maintenance Frequency | Lifecycle Nqi Efficiency |
|---|---|---|---|---|---|
| 316 Stainless Hlau Tube | Kev tiv thaiv los ntawm cov txheej txheem passivation ruaj khov, deb tshaj li 304 | Kev ntseeg tau ntev - voj voog ua haujlwm tsis tu ncua | Muaj zog tiv thaiv -scouring peev xwm | Tsuas yog kev tshuaj xyuas peb lub hlis twg xwb | Optimal tag nrho cov nqi ua tau zoo |
| 304 Stainless Hlau Tube | Yooj yim rau hauv zos pitting hauv chloride- dej nplua nuj | Nruab nrab thermal aging kuj | Ordinary anti-flushing peev | Kev tshuaj xyuas txhua hli | Tus nqi qis dua, kev pabcuam luv luv hauv dej ntsev |
| Ntshiab Titanium Heating Tube | Sab saum toj -tier anti-chloride kev ua tau zoo nyob rau hauv siab salinity | Ultra- ruaj khov siab -kub tsis kam | Zoo heev ntev -lub sij hawm scour kuj | Kev saib xyuas yooj yim - dawb | High raw khoom nqi, overqualified rau me ntsis corrosion scenarios |
| Fused Quartz Tube | Tsuas yog ruaj khov nyob rau hauv ib qho kua qaub nruab nrab, tsis zoo rau chloride -muaj kua | Thaum tshav kub kub-resistant tab sis nkig heev | Kev cuam tshuam tsis zoo | High hloov tus nqi tom qab tawg | Kev tshaj tawm siab - tus nqi kho tsis raug, tsuas yog rau qhov chaw kuaj mob static acid |
3. Inherent Deficiencies thiab Forbidden Application Scenarios
316 stainless hlau tsis yog universal los tiv thaiv - cov khoom siv 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 nruam phab ntsa thinning thiab zaum kawg to scrapping. Rau cov kev sib xyaw hnyav corrosive media, titanium cua sov raj lossis PFA- cov khoom siv cua sov yog cov khoom siv tau zoo dua.
Tsis tas li ntawd, nyob rau hauv kev ua hauj lwm nrog siab - ceev stirred cov khoom thiab cov kua abrasive cuam tshuam, cov zaj duab xis passivation yuav mechanically khawb thiab tsis kho nws tus kheej raws sij hawm, ua kom lub zos corrosion puas thiab shortening lub neej kev pab cuam ntawm cua sov raj.
4. Kev Xaiv Cov Ntsiab Cai thiab Cov Ntsiab Lus
Tau txais txiaj ntsig los ntawm molybdenum- ntxiv dag zog rau cov tshuaj chloride corrosion, cov khoom siv kho tshuab ruaj khov thiab 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 muaj qhov tseem ceeb rau cov khoom no rau cov tshuaj chloride-cov kav xa dej, khoom noj khoom haus- qib cua sov thiab ib txwm-kub dej khib nyiab preheating chaw. 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 tau lav thiab tag nrho cov peev txheej tsim nyog tswj tau.
