1. Dab tsi yog qhov txawv ntawm Inconel, Incoloy, Monel, thiab Hastelloy alloys?
Teb:
Inconel: Nickel-chromium superalloys tsim los rau siab - kub lub zog thiab oxidation kuj zoo heev (qib ntau: 600, 625, 718).
Incoloy: Nickel-hlau-chromium alloys nrog kev lag luam zoo dua Inconel, optimized rau corrosion kuj nyob rau hauv siab -kub ib puag ncig, tshwj xeeb tshaj yog sulfur ib puag ncig (xws li, 800H / HT, 825).
Monel: Nickel- tooj liab alloys muab kev tiv thaiv zoo rau cov dej hiav txwv thiab chloride ib puag ncig (xws li, 400, K-500).
Hastelloy (C-276 / X / C-2000): Nickel-molybdenum-chromium corrosion-resistant alloys haum rau cov kua qaub muaj zog, txo cov xov xwm, thiab kev ua tshuaj lom neeg heev.
2. Dab tsi kev lag luam feem ntau siv cov nickel -raws li cov kav dej thiab cov raj?
Teb:
Cov alloys no tau siv dav hauv qhov chaw huab cua, xws li:
Chemical & petrochemical ua
Roj & roj / offshore platforms
Aerospace & turbine Cheebtsam
Kev tsim hluav taws xob / cua sov exchangers
Marine & desalination systems
Pharmaceutical and pollution-tswj cov cuab yeej
Lawv xaiv nyob ntawm qhov kub thiab txias, hom corrosion, thiab mechanical stress theem.
3. Vim li cas Hastelloy C-276, Hastelloy X, thiab C-2000 thiaj nyiam nyob rau hauv kev ua tshuaj?
Teb:
Cov alloys no muab:
Cov tshuaj tiv thaiv muaj zog xws li HCl, H2SO4, formic, acetic acids
Zoo heev tiv taus pitting, crevice corrosion, thiab kev nyuaj siab corrosion cracking
High mechanical zog ntawm ob qho tib si siab thiab ambient kub
Superior weldability piv rau ntau lwm yam corrosion{0}}resistant alloys
C-276 yog tus qauv kev lag luam rau kev sib xyaw-acid ib puag ncig,
Hastelloy X rau siab -kub oxidation,
C-2000 rau kev txhim kho tiv thaiv oxidizing + txo cov xov xwm.
4. Qhov kev ntsuam xyuas dab tsi feem ntau ua rau ntawm Inconel / Incoloy / Monel / Hastelloy hlab thiab cov kav dej ua ntej xa khoom xa tuaj?
Teb:
Cov kev kuaj pom muaj xws li:
Hydrostatic los yog pneumatic siab kuaj
Eddy-tam sim no / ultrasonic NDT (tsis yog- kuaj kev puas tsuaj)
Chemical composition analysis (PMI)
Mechanical xeem: tensile, yield, elongation, hardness
Kev tshuaj xyuas microstructure / grain loj
Dimension & deg tiav soj ntsuam
Cov kev ntsuam xyuas no ua kom tau raws li ASTM / ASME cov qauv xws li ASTM B622, B564, B163, B165, B167, thiab lwm yam.
5. Dab tsi yuav tsum tau xav txog thaum xaiv cov nickel zoo-qib alloy rau ib qhov project?
Teb:
Engineers feem ntau ntsuam xyuas:
Corrosion ib puag ncig (chlorides, acids, seawater, txo vs oxidizing tej yam kev mob)
Kev khiav hauj lwm qhov kub thiab txias
Siab thiab mechanical stress
Weldability xav tau
Cov qauv kev lag luam / qhov project specifications
Nqi vs kev ua haujlwm
Hastelloy C-276 yog siv rau cov tshuaj phem tshaj plaws, Inconel 625 rau siab -kub lub zog, Monel 400 rau seawater, thiab Incoloy 825 rau kev lag luam high-temperature corrosion.
