1. Incoloy 800HT (UNS N08811) yog dab tsi thiab nws cov khoom tseem ceeb?
Teb:
Incoloy 800HT yog siab -kub npib tsib xee- hlau- chromium alloy nrog cov ntsiab lus carbon ntau ntxiv thiab tswj kev kho cua sov. Nws cov khoom tseem ceeb muaj xws li:
Kev nkag siab zoo heev thiab kev ntxhov siab- tawg tsis kam ntawm qhov kub txog li 760℃(1400℃F).
Zoo heev tiv thaiv oxidation thiab carburization.
Kev ruaj ntseg zoo nyob rau lub sij hawm ntev - lub sij hawm siab - qhov kub thiab txias, ua rau nws zoo tagnrho rau cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob.
2. Cov ntawv thov dab tsi yog Incoloy 800HT welded thiab seamless raj siv rau?
Teb:
High - kub exchangers nyob rau hauv chemical thiab petrochemical industries.
Furnaces, reformers, thiab boiler Cheebtsam.
Kev tsim hluav taws xob thiab cov txheej txheem petrochemical piping qhov twg ob qho tib si siab - qhov kub thiab txias thiab corrosion kuj yuav tsum tau.
Cov khoom siv roj thiab roj ua haujlwm hauv oxidizing thiab txo cov cua.
3. Dab tsi yog qhov txawv ntawm welded thiab seamless Incoloy 800HT raj?
Teb:
Seamless raj: Tsim los ntawm extrusion lossis rotary tho, muab lub zog zoo ib yam, kev ua haujlwm siab dua, thiab zoo tagnrho rau kev siv siab - siab.
Welded raj: Ua los ntawm kev sib sau thiab vuam ib lub strip, feem ntau yog tus nqi qis. Lawv tsim nyog rau cov ntawv thov siab me ntsis tab sis tseem muaj kev tiv thaiv corrosion thiab kub tsis kam.
Qhov kev xaiv nyob ntawm qhov kev pab cuam, siab, thiab pob nyiaj siv.
4. Cov raj Incoloy 800HT puas tuaj yeem welded thiab fabricated yooj yim?
Teb:
Yog, tab sis nrog ceev faj:
Siv cov khoom siv sib xyaw ua ke (xws li Alloy 800 muab tub lim) rau vuam.
Preheating feem ntau tsis tas yuav tsum tau ua, tab sis tom qab -weld stress relief tuaj yeem txhim kho kev ua haujlwm nyob rau hauv siab - qhov kev pab cuam kub.
Cov raj tuaj yeem khoov, flared, lossis tsim, tab sis yuav tsum tau saib xyuas kom tsis txhob ua haujlwm hnyav lossis qhov chaw tsis xws luag uas tuaj yeem cuam tshuam kev tiv thaiv corrosion.
5. Vim li cas Incoloy 800HT yog qhov kev xaiv zoo tshaj plaws rau siab -kub kub exchangers?
Teb:
Ua ke zoo heev siab - kub lub zog nrog oxidation thiab carburization kuj.
Xyuas kom ntev - lub sij hawm seem stability nyob rau hauv thermal cycling.
Txo kev txij nkawm thiab kev poob qis vim nws ua haujlwm ntev hauv cov tshuaj hnyav thiab siab - qhov kub thiab txias.
Muaj nyob rau hauv cov ntaub ntawv welded thiab seamless, muab kev yooj yim hauv kev tsim thiab tus nqi ua haujlwm.
