Q1: Dab tsi yog qhov txawv ntawm Hastelloy, Inconel, Incoloy, thiab Monel kav?
Teb:
Hastelloy: High corrosion kuj, tshwj xeeb tshaj yog tiv thaiv oxidizers thiab acids zoo li hydrochloric thiab sulfuric acids. Zoo tagnrho rau kev ua tshuaj.
Inconel: Lub zog siab ntawm qhov kub siab, zoo heev oxidation thiab kub tsis kam. Siv nyob rau hauv aerospace, turbines, thiab tshav kub exchangers.
Incoloy: Resistant rau ob qho tib si oxidation thiab carburization ntawm qhov kub thiab txias. Feem ntau hauv kev siv tshuaj thiab petrochemical.
Monel: Zoo heev tiv thaiv dej hiav txwv corrosion thiab alkalis. Feem ntau siv nyob rau hauv marine thiab tshuaj ib puag ncig.
Cov ntsiab lus: Hastelloy yog rau cov tshuaj tiv thaiv huab cua, Inconel rau siab - kub lub zog, Incoloy rau siab - kub corrosion, Monel rau marine / alkali tsis kam.
Q2: Dab tsi seamless yeeb nkab loj thiab qhov ntev yog muaj rau cov alloys?
Teb:
Seamless kav muaj nyob rau hauv ntau txoj kab uas hla (OD 1/2 "- 24" lossis loj dua) thiab phab ntsa tuab nyob ntawm cov neeg siv khoom.
Cov qauv ntev feem ntau yog 6m, 12m, lossis txiav - mus rau - ntev rau ib qho kev txiav txim.
Cov qauv: ASTM B622/B574/B637/B168, ASME SB165, SB163.
Q3: Cov kav dej hlau no ua haujlwm li cas hauv qhov kub thiab txias?
Teb:
Inconel 625, 718, 725: Lub zog zoo heev txog 1000 degree.
Hastelloy C276: ruaj khov mus txog 600 degree, tswj kev tiv thaiv corrosion.
Incoloy 800, 825: Zoo oxidation thiab creep kuj mus txog 1100℃F (~ 593 degree).
Monel 400: Tsis yog rau qhov kub siab heev; max ~ 400-500 degree, feem ntau corrosion kuj.
Q4: Dab tsi yog cov ntawv thov rau cov kav hlau tsis sib haum no?
Teb:
Hastelloy C276: Tshuaj reactors, acid tuav, seawater kho, tshuaj ua.
Inconel 625/718: Gas turbines, aerospace, nuclear, siab -kub cua tshuab.
Incoloy 800/825: Petrochemical heaters, furnace tubes, nuclear steam generators.
Monel 400: Marine piping, hydrocarbon tuav, seawater txias tshuab.
Q5: Yuav ua li cas koj txiav txim siab txoj cai alloy rau ib qhov project tshwj xeeb?
Teb:
Corrosive Ib puag ncig: Xaiv Hastelloy rau cov kua qaub muaj zog, Monel rau seawater / alkali.
Temperature Requirement: Inconel rau siab -kev siv kub, Incoloy rau nruab nrab- kub.
Mechanical Load: Xav txog lub zog tensile thiab creep tsis kam (Inconel 718 muaj zog dua 625).
Nqi & Muaj: Hastelloy kim dua; Monel yog nruab nrab; Incoloy/Inconel nyob ntawm qib.
Cov Qauv Ua Tau Zoo: Tshawb xyuas ASTM / ASME / GOST cov qauv rau siab, qhov ntev, thiab ntawv pov thawj.
