Q1: Dab tsi cov ntaub ntawv thiab specifications muaj rau cov seamless nickel alloy kav thiab raj?
A1: • Cov ntaub ntawv muaj: Hastelloy (C-22, C-276, B2), Monel 400/K500, Inconel 600/601/625, Incoloy 800/825. • Ua raws li ASTM cov qauv xws li B165, B564, B409, B829 nyob ntawm cov alloy. • Cov kav dej thiab cov raj yog seamless, ua kom muaj kev ncaj ncees rau kev kub siab, kub kub, thiab kev siv corrosive.
Q2: Dab tsi yog qhov kub thiab kev tiv thaiv corrosion ntawm cov hlau no?
A2: • Hastelloy: Zoo heev tiv thaiv oxidation, muaj zog acids, thiab halide ib puag ncig; siv tau mus txog 700 degree. • Monel 400/K500: Resistant rau dej hiav txwv, alkalis, thiab acids; siv tau mus txog 315 degree. • Inconel 600/601/625: Siab zog ntawm 600-980 degree, zoo heev oxidation thiab corrosion kuj. • Incoloy 800: Zoo tiv thaiv oxidation thiab carburization, haum rau 1090 degree.
Cov khoom no ua rau lawv zoo tagnrho rau kev siv tshuaj lom neeg, petrochemical, roj & roj, thiab kev siv fais fab nroj tsuag.
Q3: Dab tsi yog qhov loj me thiab qhov loj me feem ntau muaj rau cov kav dej thiab cov kav dej tsis sib haum?
A3: • Sab nraud txoj kab uas hla: 6 mm - 500 mm (qhov ntau thiab tsawg muaj). • Phab ntsa thickness: 1 mm – 50 mm. • Ntev: 6-12 meters tus qauv, tuaj yeem txiav - mus rau - ntev raws li qhov xav tau ntawm qhov project. • Muaj nyob rau hauv kub- dov, txias{13}} kos, lossis polished tiav nyob ntawm daim ntawv thov.
Q4: Puas yog cov nickel alloy cov kav dej thiab cov kav hlau txuas tau thiab ua tau zoo?
A4: • Vuam: Haum rau TIG, MIG, los yog tsis kam vuam. Qee cov alloys (xws li Monel K500, Inconel 718) yuav tsum tau preheating los yog tom qab-weld stress relief. • Machining: Alloys yog machinable nrog siab - cov cuab yeej ceev thiab coolant, tab sis ua hauj lwm - hardening alloys zoo li Monel K500 yuav tsum tau ceev faj tuav. • Kev tsim: Kub lossis txias ua tau; kev daws annealing tej zaum yuav xav tau rau tej yam alloys ua ntej nws kim heev dabtsi yog khoov.
Q5: Cov kev lag luam twg uas feem ntau siv cov seamless nickel alloy kav thiab raj?
A5: • Roj & Roj: Downhole tubing, piping systems, li qub, thiab kub exchangers. • Tshuaj & Petrochemical: Corrosive tshuaj tuav, reactors, thiab ua kab. • Kev Tsim Hluav Taws Xob: Boiler, turbine, thiab cov khoom siv rauv. • Marine: Seawater tuav systems thiab desalination nroj tsuag. • Aerospace: Cov tshuab pa tawm, siab - qhov kub thiab txias, thiab cov khoom siv tseem ceeb.
