Tuavsulfuric acidYuav tsum tau muaj zog, corrosion-resistant cov ntaub ntawv. 316L stainless hlau Piping tau dhau los ua qhov kev xaiv zoo tshaj plaws vim nws cov tshuaj lom neeg zoo heev thiab tshuab muaj zog. Txawm li cas los xij, nyob rau hauv kev mob accuse acidic, ntxiv corrosion tswj cov tswv yim zoo lianodic kev tiv thaivyog qhov tseem ceeb los txuas txoj kev pabcuam lub neej thiab tswj kev ncaj ncees. Hauv cov blog no, peb ntseej rau hauv cov txheej txheem tshuaj, kev tsim khoom ntawm 316L piping, thiab yuav ua li cas Anodic kev tiv thaiv nyab xeeb tshaj plaws hauv sulfuric acid thov.
Cov ntsiab lus:316L stainless hlau, cov kev tiv thaiv anodic, sulfuric piping, sulfuric kev tiv thaiv, kev tiv thaiv piping, stainless hlau anodic tiv thaiv.
Vim li cas Sulphuric Acid Sib Tw Cov Hlau Stainless
Sulfuric acid (hatso₄)Puas yog ib qho ntawm cov tshuaj lag luam ntau tshaj plaws, tseem ceeb hauv cov chav xws li kev ua chiv, tshuaj lom neeg, thiab kev kho kom huv. Txawm li cas los xij, nws cov khoom siv oxidatative thiab lub cev qhuav dej ua rau nws muaj feem cuam tshuam rau cov hlau, suav nrog stainless hlau.
Thaum316L stainless hlau-composed feem ntau ntawmHlau, chromium (16-18%), npib tsib xee (10-14%), thiab Molybdenum (2-3%)-Offers ua kom haum corrosion ua piv rau tus qauv 304 stainless hlau, ua rau pitting txheej, ua rau pitting thiab crevice corrosion yam tsis muaj kev tiv thaiv kom tsim nyog.
Kev tsim khoom txheej txheem ntawm 316L stainless hlau
Ua kev ua haujlwm siab316L stainless hlau Rau cov sulfuric acid systems cuam tshuam nrog cov txheej txheem kev tsim khoom me me:
1.Traw cov khoom so
High-huv hlau hlau ee, chromium, npib chromium, thiab molybdenum yog muaj, feem ntau los ntawm cov chaw hauv ntiaj teb loj hauv South Africa, Australia, thiab Russia.
2.melting thiab alloying
Cov ntaub ntawv raw no tau melted nyob rau hauv ib qho hluav taws xob arc. Precise ntau tus nqi ntawm chromium, npib tsib xee, thiab molybdenum tau ntxiv los ua 316L muaj pes tsawg leeg, nrog cov tshuaj muaj roj carbon tsawg (<0.03%) to enhance weldability and reduce carbide precipitation.
3.Hot thiab txias ua haujlwm
Tom qab tau ua rau hauv cov tsiaj xev, cov hlau undergoes kub dov mus rau cov kav dej, ua raws cov txheej txheem txias thiab txhim kho cov khoom siv neeg kho khaub ncaws.
4. ankution annaling
Cov kav dej yog cov cua sov-kho (daws anealed) ntawm ib ncig ntawm 1,040-1,120 degree kom yaj thiab rov kho corrosion tsis kam.
5.Pov thiab caij nyoog
Kev kho tshuaj zaum kawg tshem tawm saum npoo impurities thiab tsim cov chromium-nplua nuj oxide passive zaj duab xis uas muaj kev tiv thaiv corrosion.
6.Qhov kev tswj hwm
Tsis yog-kev sim ua phem (NDT), kev tshuaj xyuas qhov ntev, thiab cov tshuaj lom neeg txheeb xyuas kom haum li ntawd txhua cov yeeb nkab ua tau raws li ATTM A312 lossis cov qauv sib npaug.

Anodic Kev Tiv Thaiv: Kev Tiv Thaiv Qhov Kawg Tawm tsam tiv thaiv sulfuric acid corrosion
Txawm tias qhov zoo tshaj plaws316L Cov txiaj ntsig los ntawm kev tiv thaiv corrosion hauv cov kev pheej hmoo siab sulfuric acid.Anodic kev tiv thaivyog cov txheej txheem electrochemical zoo heev uas tiv thaiv cov hlau los ntawm kev tswj hwm nws hauv lub xeev passive.
1. Cas Anodic Kev Tiv Thaiv Ua Haujlwm
- Tswj muaj peev xwm
Ib qho kev tiv thaiv anodic tswj cov hlau saum npoo hlau ntawm ib qho kev muaj peev xwm ntawm cov muaj peev xwm ruaj khov uas muaj qhov ruaj khov, xeb-desistant passive zaj duab xis tseem muaj zog.
- Daim Ntawv Thov Tam Sim No
Ib qho me me anodic tam sim no tau thov rau 316L piping ntawm sab nraud fais fab ntawm lub zog, txo cov kev sib cais ntawm cov hlau kom yuav luag cov neeg saib xyuas qib.
- Kev soj ntsuam System
Niaj hnub nimno lub tshuab siv sensors thiab controllers los saib xyuas lub peev xwm thiab kho qhov tam sim no, ua kom muaj kev pom zoo txuas ntxiv.
2.Advantages ntawm anodic tiv thaiv rau 316L
- Drastically txo cov nqi corrosion, txuas ntxiv ua hauj lwm lifespan ntawm cov twj piping.
- Minimizes tu nqilos ntawm kev tiv thaiv so thiab tsis ua tiav.
- Txhim kho cov txheej txheem kev nyab xeeb, tseem ceeb hauv kev lag luam kov cov sulfuric acid.
- Txo tus nqi tag nrho ntawm cov tswv cuabpiv rau cov yeeb nkab nquag hloov.
Anodic kev tiv thaiv ntawm 316L Stainless hlau kav hauv sulfuric acid kev pabcuam: kev ua tsis tiav cov teeb meem thiab kev ua haujlwm
Anodic kev tiv thaiv (AP) yog ib txoj kev tswj hwm ntawm corrosion uas tau siv dav hauv kev tsim khoom, khaws cia, thiab thauj khoom ntawm sulfuric acid. Lub khoos kas AP muaj qhov chaw ncaj qha, Cathodes, siv cov hluav taws xob, thiab cov paib hluav taws xob. In a sulfuric manufacturing plant, for AP of 316L piping (as an anode), platinized titanium (Pt/Ti) and Hastelloy B-2 were used as reference and cathode electrodes, respectively. Tom qab xya xyoo kev ua haujlwm ntawm AP kab kab hauv sulfuric acid cog, ib tshooj ntawm cov neeg muaj kev tiv thaiv cov kab corroded hnyav. Kev tshawb fawb ntawm lub kaw lus pom tias cov ntaub ntawv siv hluav taws xob, uas yog titanium-electroplated nrog platinum, ploj lawv ruaj khov nyob rau hauv cov txheej thiab ua rau muaj kev cuam tshuam. Txawm li cas los xij, lub kaw lus tsis tuaj yeem tswj cov yeeb nkab lub peev xwm hauv AP txheej xwm. Hauv cov xwm txheej no, nrawm corrosion ntawm lub Cathodes thiab kav dej kuj tau tshwm sim.
