Corrosion Resistance
Sulfuric Acid
Ib qho ntawm cov laj thawj tseem ceeb tshaj plaws rau kev xaiv Alloy 825 yog nws qhov kev ua tau zoo nyob rau hauv ib puag ncig sulfuric acid.
Cov npib tsib xee- tooj liab- molybdenum ua ke muab kev txhim kho kev tiv thaiv kom txo cov kua qaub piv nrog cov qauv stainless hlau.
Phosphoric Acid
Alloy 825 yog dav siv nyob rau hauv phosphoric acid ua, tshwj xeeb tshaj yog nyob rau hauv impurities tsim ib tug aggression ib puag ncig ntau dua li kuaj - qib acid.
Fluorides, chlorides, sulfur compounds, thiab cov txheej txheem cov kab mob tuaj yeem hloov pauv tus cwj pwm corrosion.
Chloride Ib puag ncig
Alloy 825 muab kev tiv thaiv zoo rau chloride-induced corrosion piv nrog cov pa austenitic stainless hlau.
Txawm li cas los xij, nws yuav tsum tsis txhob txiav txim siab sib npaug rau super-austenitic stainless hlau, Alloy 625, lossis Hastelloy C276 hauv kev pabcuam chloride hnyav heev.
Intergranular Corrosion
Titanium stabilization yog qhov tseem ceeb ntawm Alloy 825.
Qhov sib ntxiv ntawm titanium pab tswj cov txheej txheem no thiab ua rau Alloy 825 haum rau fabricated thiab welded khoom.
Daim ntawv thov
- Roj & Roj Kev Lag Luam:Kev tsim cov tubing thiab cov kab sib sau ua ke tuav cov pa roj qaub (H2S thiab CO2 kwj) thiab chloride-laden tsim dej.
- Marine & Seawater Systems:Tawm ntawm - ntug dej hiav txwv piping, seawater cooling loops, thiab subsea hydraulic tswj kab.
- Kev Siv Tshuaj:Piping systems tuav sulfuric acid ntau lawm, phosphoric acid evaporators, pickling acid tanks, thiab acid regeneration nroj tsuag.
- Pollution Control & pov tseg kho:Flue gas desulfurization (FGD) scrubber Cheebtsam, tshuaj khib nyiab pov tseg piping, thiab acid gas scrubbers.

Yuav ua li cas kom tsis txhob vuam tsis ua hauj lwm?
Inconel 825 muaj titanium, uas ua rau lub microstructure ruaj khov tiv thaiv cov nplej - ciam teb chromium carbide nag lossis daus thaum vuam. Txawm li cas los xij, kom tsis txhob muaj microfissuring hauv hnyav-section welds, siv cov khoom siv sib xyaw ua ke (xws li AWS A.14ERNiFeCr-1 lossis ENiCrMo-3nyob ntawm dilution yuav tsum). Ntxuav tag nrho cov roj, roj, thiab leej faj- cov kab cim cim ua ntej vuam; sulfur paug ntawm qhov kub thiab txias ua rau kub tawg.
Case: Kev Ntsuam Xyuas Tsis Zoo hauv Sulfuric Acid Service
Ib qho kev cog qoob loo tsis zoo tshwm sim thaum cov kav dej muaj kev cuam tshuam hauv cheeb tsam ntawm cov pob qij txha vim yog qhov tsis raug - vuam tu. Cov hlau tsis pub dawb sab laug los ntawm cov cuab yeej carbon steel thaum lub sijhawm teeb tsa tuaj yeem pib pitting hlwb. Ib txwm hais kom pickling thiab passivation (siv nitric -hydrofluoric acid blends) post- txhim kho kom rov qab tau cov chromium passive- nplua oxide zaj duab xis.
Puas yog post-weld heat treatment (PWHT) yuav tsum tau rau ASTM B704 welded Inconel 825 kav?
Feem ntau, PWHT tsis tas yuav muaj kev tiv thaiv corrosion vim tias cov ntsiab lus titanium stabilizes cov hlau tiv thaiv carbide nag lossis daus. Annealing tsuas yog teev yog tias qhov siab tshaj plaws ductility yuav tsum tau tom qab txias txias heev.
Inconel 825 Seamless Welded Tubes Ntim
Lub pob peb feem ntau yog ntim cov hlab nrog ib puag ncig poly hnab, thiab tom qab ntawd hauv cov ntoo fumigation dawb lossis ntoo palte. Kuj tseem tuaj yeem txais pob customized xws li OEM los ntawm kev sib tham. Peb tsuas yog muab txhua yam kom tau raws li cov kev xav tau ntawm pob.

Alloy 825 vs 316L
316L feem ntau yog qis dua - tus nqi xaivrau kev siv tshuaj lom neeg thiab kev lag luam.
Txawm li cas los xij, thaum sulfuric acid concentration, chloride cov ntsiab lus lossis txo cov xwm txheej ua rau muaj kev txhoj puab heev, 316L yuav muaj kev cuam tshuam hauv cheeb tsam lossis kev ntxhov siab corrosion tawg.
Alloy 825 muab qhov tseem ceeb corrosion-kuj hloov kho.
Thaum twg los hloov kho los ntawm 316L mus rau Inconel 825: Yog tias 316L piping nthuav tawm ntxov ntxov chloride stress corrosion cracking (CSCC) los yog nyias nyias hauv cov kua qaub pov tseg, Inconel 825 ua hauj lwm raws li kev lag luam npib tsib xee -alloy kauj ruam- nce ua ntej tsiv mus rau siab dua {{6}.
Alloy 825 vs Alloy 625
Alloy 625 muab lub zog ntau dua thiab zoo heev corrosion kuj, tshwj xeeb tshaj yog nyob rau hauv siab kub.
Txawm li cas los xij, feem ntau nws kim dua.
Rau sulfuric acid, phosphoric acid thiab sib xyaw cov kua qaub ib puag ncig qhov chaw siab heev - qhov kub thiab txias tsis tas yuav tsum muaj,Alloy 825 tuaj yeem muab tus nqi zoo dua - rau - kev ua tau zoo.
Thaum txo qis los ntawm Alloy 625 mus rau Inconel 825: Yog tias qhov ntsuas kub ua haujlwm qis dua 550℃thiab tus neeg sawv cev corrosive yog aqueous sulfuric lossis phosphoric acid es tsis muaj siab heev - kub chloride kev ntxhov siab, hloov los ntawm Alloy 625 mus rau Inconel 825 txo cov khoom siv los ntawm 3% kev siv nyiaj.
Alloy 20 vs Incoloy 825: Uas Zoo dua rau Sulfuric Acid Service?
Alloy 20 excels nyob rau hauv sulfuric acid ib puag ncig (tag nrho cov concentrations), thaum Incoloy 825 muaj kev tiv thaiv dav xws li phosphoric, nitric acids, thiab zoo dua pitting / crevice resistance hauv chlorides.
- Yog tias koj cov txheej txheem nruab nrab yog sulfuric acid, Alloy 20 feem ntau yog thawj alloy los ntsuas.
- Yog tias lub kaw lus muaj kev sib xyaw ua ke ntawm cov kua qaub, chlorides, raug dej hiav txwv, lossis cov tshuaj roj thiab roj, Alloy 825 feem ntau yog qhov kev xaiv ntau yam.
