Cov Lus Qhia Tseem Ceeb rau Kev Siv Boiler
SA-53 vs SA-53M:"SA-53" yog lub npe ASME, thaum "A53" yog ASTM tus qauv. Lawv yog technically zoo tib yam thaum saws los ntawm ASME.
Boiler Code Ua raws:Rau kev siv fais fab boiler, SA-53 tej zaum yuav raug siv rau qee yam tsis tseem ceeb piping rauASME Boiler thiab Pressure Vessel Code, Tshooj I. Txawm li cas los xij,SIB-106yog feem ntau nyiam rau siab -kub boiler daim ntaub ntawv.
Kev txwv siab:Kev siv feem ntau yog txwv rau:
Qhov siab tshaj plaws: Nws txawv ntawm daim ntawv thov
Kub: Feem ntau qis dua 427℃(800℃F)
Cov ntsiab lus
SA-53 Qib Byog antau yam carbon steel yeeb nkabsiv dav rau cov kav dej dav dav, kev siv cov qauv, thiab qee qhov kev siv boiler. Nws muaj qhov sib npaug zoo ntawm lub zog, weldability, thiab tus nqi -kev ua tau zoo. Thaum tsim nyog rau qee lub boiler-txog cov kav dej (tshwj xeeb yog qis dua- kev siv siab thiab kub), nws tsis yog tshwj xeeb "boiler steel" xws li SA-213 lossis SA-335 qib siv rau cov cua kub superheater lossis reheater raj. Nws cov koob meej tshwm sim los ntawm nws qhov dav dav, tus nqi qis, thiab tsim nyog rau ntau yam kev siv hauv kev lag luam.
