Cov yeeb nkab twg yog qhov zoo tshaj plaws rau kev kub siab
Sep 27, 2023
Ntau cov ntaub ntawv feem ntau yog siv rau cov kav dej kub kub, thiab qhov tsim nyog ntawm txhua yam khoom nyob ntawm qhov kev xav tau ntawm daim ntawv thov. Nov yog qee cov khoom siv feem ntau siv rau cov kav dej kub kub:
Stainless Hlau: Stainless hlau, tshwj xeeb tshaj yog cov qib siab kub zoo li 310S, 321, thiab 347, yog qhov kev xaiv zoo tshaj plaws rau kev siv kub. Nws muaj kev tiv thaiv corrosion zoo thiab khaws nws lub zog thiab kev ncaj ncees ntawm qhov kub thiab txias. Stainless hlau feem ntau yog siv nyob rau hauv industrial furnaces, pa system, thiab tshav kub exchangers.
Cov pa roj carbon steel: Qee cov qib carbon steel tuaj yeem tsim nyog rau cov ntawv thov kub nruab nrab (feem ntau txog li 450-600 degree lossis 850-1112 degree F) nrog kev kho cua sov kom zoo. Txawm li cas los xij, carbon hlau tuaj yeem raug oxidation thiab corrosion ntawm kub dua.
Alloy Steel: Alloy steel kav, zoo li P5, P9, P11, thiab P22, feem ntau yog siv rau kev siv kub. Lawv muaj lub zog zoo thiab ua haujlwm rau oxidation thiab siv rau hauv cov chaw tsim hluav taws xob thiab cov boilers.
tsis kam. Lawv yog siv nyob rau hauv aerospace thiab chemical ua.
Nws yog ib qho tseem ceeb uas yuav tsum xav txog tsis yog cov khoom siv lub peev xwm los tiv thaiv qhov kub thiab txias, tab sis kuj tseem muaj kev tiv thaiv corrosion, siab, thiab kev ua haujlwm tshwj xeeb ntawm daim ntawv thov. Tsis tas li ntawd, yam xws li tus nqi, muaj, thiab kev yooj yim ntawm fabrication ua lub luag haujlwm hauv kev xaiv cov khoom. Kev sab laj nrog cov ntaub ntawv engineers thiab xa mus rau cov qauv kev lag luam thiab cov lej yog qhov tseem ceeb los ua qhov kev xaiv zoo tshaj plaws rau ib daim ntawv thov tshwj xeeb ntawm cov kav dej kub.
