Nickel Alloy Flanges tsim los ua Asme Cov Qauv-xws li B16.5 thiab B16.5 thiab B16. {}}}}} Yog tsim tshwj xeeb corrosion tsis kam nyob rau hauv ib puag ncig muaj kev ntxhov siab. Ntawm no yog li cas:
✅ Kev tiv thaiv zoo dua rau cov chaw hnyav
Nickel alloys nyiamInconel (piv txwv li, 625, 718), Monel (400), Hastelloy (C22, C276), thiabIncoloy (800, 825)Kev nthuav tawm tsis kam:
Acids(hydrochloric, sulfuric, nitric)
Alkaline Solutions
Salwater thiab Marine cua
Kev kub-kub oxidizing thiab txo cov mob
✅ Cov khoom muaj pes tsawg leeg rau kev tiv thaiv corrosion
Cov alloys muaj feem pua ntawm cov feem pua ntawmNickel (ntau dua lossis sib npaug nrog 50%), nrog rau chromium, molybdenum, hlau, thiab tooj liab, uas txhim kho tiv thaiv:
Pitting thiab crevice corrosion
Kev ntxhov siab corrosion cracking (SCC)
Intergranular corrosion
✅ Kev Lag Luam Kev Lag Luam
ASME-Raws Nickel Alloy Flanges tau siv dav hauv:
Tshuaj Nroj Tsuag
Offshore thiab marine tshuab
Nuclear thiab fais fab tiam
Desalination thiab Wastewater system
✅ Qauv Ua Haujlwm
Flanges ua los ntawm nickel alloys ua rawsASME B16.5, B16.47, thiabB564, kom ntseeg tau tias lawv tau ua tiav qhov tseem ceeb thiab cov lus qhia siab thaum muaj kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv ntev.
✅ Nickel Alloy Corrosion Kev sib piv
| Hlau | Nickel (%) | Qhov Tseem Ceeb Alloying Ntsiab Lus | Corrosion Kuj | Zoo tshaj plaws cov chaw |
|---|---|---|---|---|
| Inconel 625 | ~58% | Cr, mo, nb | Zoo heev rau cov acids, seawater, cov siab-temp oxidation, pitting, scc | Tubrog Nkoj, Tshuaj lom neeg, Aerospace, lub hwj chim loj |
| Inconel 718 | ~50–55% | CR, FE, NB, MO, TI | Muaj zog ntawm Temps High, zoo oxidation thiab corrosion tsis kam | Kev siab siab \/ siab-temp systems, dav hlau tshuab |
| Monel 400 | ~63% | CU (~ 30%) | Zoo heev nyob rau hauv hiav txwv thiab hydrofluoric acid, tab sis txwv tsis kam mus oxidizing acids | Tubrog Nkoj, Tshuaj Lom Zem, Roj & Roj & Roj |
| Hastelloy C276 | ~57% | Mo, CR, FE, W | Koj tsis kam kam rau muaj zog oxidizers, acids, chloride kev ntxhov siab corrosion | Kev Siv Hluav Taws Xob Kev Nyab Xeeb, Kev Kho Khib Khib |
| Hastelloy C22 | ~56% | Cr, mo, FE, W | Zoo dua tsis kam rau oxidizing thiab txo cov xov xwm tshaj C276 | Kws muag tshuaj, pulp & ntawv, nuclear, tswj kev paug |
| Incoloy 825 | ~38–46% | FE, CR, MO, CU | Muaj zog tsis kam rau sulphoric thiab phosphoric acids, chloride scc | Cov kua nyeem kua tshuaj tso tsheb hlau luam |
| Incoloy 800H \/ HT | ~30–35% | FE, CR | Cov tshuaj oxidation zoo thiab carburization tsis kam kam ua kom sov siab | Cov Khoom Siv Tshav Kub Kub, Reformers, Fais Fab Cog Khoom |
