1. Cov ntaub ntawv dab tsi muaj rau cov kav dej thiab cov kav dej seamless?
Teb:
Cov kav dej thiab cov raj no yog tsim los ntawm siab -kev ua tau zoo nickel thiab nickel{1}}raws li alloys, suav nrog:
Hastelloy C-276 - zoo heev corrosion kuj rau muaj zog oxidizing thiab txo qhov chaw.
Inconel Series (400, 600, 601, 625, 718, 725, 750, 800, 825) - siab - kub lub zog thiab oxidation kuj.
Incoloy Series – nickel{0}}hlau-chromium alloys haum rau kev siv tshuaj thiab kev lag luam.
Monel - npib tsib xee{0}} tooj liab alloy nrog zoo heev tiv taus dej hiav txwv thiab kua qaub.
Stainless hlau (SS Series) - siab corrosion kuj thiab kav ntev rau kev lag luam siv.
2. Dab tsi yog cov qauv thiab qhov loj me rau cov kav dej thiab cov kav dej seamless?
Teb:
Cov Qauv: ASTM B167, ASTM B165, ASTM B564, ASTM B622, ASTM B423 rau npib tsib xee alloys.
Sab nraud txoj kab uas hla (OD): Feem ntau yog li ntawm 6 hli mus rau 610 hli (qhov ntau thiab tsawg muaj).
Phab ntsa Thickness: 1 hli - 50 hli nyob ntawm cov khoom siv thiab qib siab.
Ntev: Txheem 6 m lossis 12 m; tuaj yeem txiav - mus rau - ntev ib tus neeg yuav tsum tau ua.
Cov kav dej thiab cov raj no yog seamless, kom ntseeg tau tias muaj kev ua haujlwm siab zoo thiab kev ua haujlwm zoo corrosion.
3. Dab tsi kev lag luam feem ntau siv cov kav dej thiab cov kav dej seamless?
Teb:
Tshuaj & Petrochemical: Corrosion-Reactors tiv taus, kub exchangers, thiab piping systems.
Lub Hwj Chim Muaj Peev Xwm: Siab - kub thiab siab - cov ntawv thov siab xws li boiler raj thiab turbine Cheebtsam.
Aerospace: Siab -kev ua tau zoo Inconel 718 thiab 625 kav rau cov khoom siv cav.
Marine & Offshore: Monel thiab Inconel rau seawater tuav systems, li qub, thiab twj tso kua mis.
Pharmaceutical & Khoom noj khoom haus: Stainless hlau series rau tu cev thiab corrosion - ua haujlwm dawb.
4. Dab tsi yog qhov zoo ntawm kev siv cov kav dej seamless tshaj welded kav?
Teb:
Tsis muaj weld seam: Tshem tawm cov ntsiab lus tsis muaj zog uas yuav ua rau tawg lossis ua tsis tau raws li qhov siab.
Kev kub siab tsis kam: Seamless tsim tso cai rau kev ua haujlwm siab dua.
Superior corrosion kuj: Uniform metallurgy txhim khu tshuaj tiv thaiv.
High -kub kev ua haujlwm: Haum rau kev siv cua sov heev yam tsis muaj kev pheej hmoo ntawm seam tsis ua haujlwm.
5. Yuav ua li cas cov kav dej thiab cov kav dej nickel alloy yuav tsum tau khaws cia kom ntev - siv sijhawm?
Teb:
Khaws rau hauv qhov chaw qhuav, npog kom tsis txhob muaj qhov paug tawm thiab oxidation.
Kev tshuaj xyuas ib ntus rau qhov chaw scaling los yog deposits nyob rau hauv corrosive ib puag ncig.
Siv cov kev kho cua sov kom tsim nyog lossis annealing raws li kev pom zoo rau cov alloys tshwj xeeb (xws li, tshuaj annealing rau Hastelloy C-276).
Tsis txhob sib cuag nrog cov hlau tsis sib xws uas yuav ua rau galvanic corrosion.
Tsis tu ncua ntxuav thiab passivate stainless hlau thiab npib tsib xee alloys kom muaj kev tiv thaiv corrosion.
