Tiag -Kev Kawm Txuj Ci Ntiaj Teb
316L vs Alloy 20 nyob rau hauv acidified dej loops
Ntau tus engineers hloov 316L nrog Alloy 20 tom qab tau ntsib "pitting" lossis "riam-kab nres" ze rau thaj tsam weld hauv cov dej acidified.
"Vim li cas 316L Reducers tsis ua haujlwm hauv Sulfuric Acid Service?"
Ib qho kev sib tham ntawm cov kws tsim tshuaj lom neeg yog qhov ua tsis tiav ntxov ntawm stainless hlau reducers ntsia hauv sulfuric acid systems.
Tej yam tsis ua hauj lwm mechanism:
- Stainless hlau passive zaj duab xis tawg.
- Sulfuric acid tawm tsam cov hlau - nplua nuj matrix.
- Reducer weld cheeb tsam corrode sai dua.
- Leakage tshwm sim ntawm weld seams.
Ntau tus engineers tau tshaj tawm tias hloov 316L nrog Alloy 20 txuas ntxiv lub neej kev pab cuam.
Engineering Lesson
316L tsis yog universal chemical alloy.
Rau sulfuric acid:Alloy 20 feem ntau yog qhov kev txhim kho kev lag luam ua ntej kim nickel alloys.
904L vs Alloy 20 hauv dilute acid
Yog hais tias ib puag ncig tsis nruj heev (piv txwv li, dilute acid nkaus xwb), xav txog kev kho dua tshiab rau 904L es tsis txhob Alloy 20 kom muaj peev xwm txo cov nqi khoom thaum tswj kev tiv thaiv corrosion.
"Puas Alloy 20 Welded Zoo li Stainless Hlau?"
Yog, tab sis cov txheej txheem vuam yuav tsum tau tswj. Alloy 20 yog raug rau kub tawg yog hais tias lub tshav kub input ntau dhau. Ib txwm siv ER320LR muab tub lim hlau thiab tswj qhov kub ntawm qhov sib txawv.
| Yam khoom | Kev pom zoo |
| Vuam txheej txheem | GTAW/TIG |
| Filler | ER 320 LR |
| Tiv thaiv Gas | Ntshiab Argon |
| Interpass kub | Tsawg dua lossis sib npaug li 150 degree |
| Ntxuav | Cov cuab yeej tshwj xeeb stainless hlau |
"Puas Alloy 20 fittings tuaj yeem txuas ncaj qha mus rau 316L piping yam tsis muaj kev hloov pauv?"
Kev sib txuas ncaj qha tuaj yeem siv cov hlau sib txuam (xws li AWS A5.14 ERNiCrMo-3 lossis ENiCrFe-2 nyob ntawm qhov xav tau sib koom ua ke), tab sis kev sib xyaw thiab kev tiv thaiv corrosion ntawm cov vuam sib txuas yuav tsum tau ua tib zoo tswj los ntawm cov kws ua haujlwm vuam.
"Puas Alloy 20 concentric reducers ua rau muaj kev ntxhov siab corrosion cracking hauv siab -kub chloride daim ntaub ntawv?"
Alloy 20 concentric reducers have excellent resistance to chloride stress corrosion cracking compared with 304/316 stainless steel. They are usually a safe choice for chemical processing systems containing chlorides. However, in very high-temperature >100℃(212℃F), siab -chloride ib puag ncig, tshwj xeeb tshaj yog nrog tensile stress lossis chloride concentration vim evaporation, SCC tseem tuaj yeem tshwm sim.
Kev saib xyuas Reducer:
Tsis tu ncua tshuaj xyuas lub reducer rau phab ntsa nyias yog tias tuav siab - nrawm slurry, vim Alloy 20 muaj zog tab sis tsis tiv thaiv kev yaig loj heev - corrosion.
