TS EN 10216-1 Seamless Carbon Steel Tubes rau Lub Hom Phiaj Siab
TS EN 10216-1yog ib qho tseem ceeb nyob sab Europe tus qauv rauseamless non{0}}alloy thiab alloy steel tubesnpaj rausiab thiab mechanical kev siv ntawm ambient thiab siab kub. Thaum tau teev tseg rau "Carbon Steel Boiler" siv, nws feem ntau yog hais txog cov qib tsis yog- alloy steel nyob rau hauv tus qauv no haum rau cov khoom siv boiler tshwj xeeb ua haujlwm ntawm qhov kub nruab nrab.
Cov yam ntxwv tseem ceeb ntawm EN 10216-1
Tsis zoo li cov qauv welded raj (EN 10217 series),TS EN 10216-1 npog seamless raj nkaus xwb, muab ntau yam zoo rau kev siv siab:
Tsis muaj weld seam: Tshem tawm cov ntsiab lus tsis muaj zog thiab kev soj ntsuam vuam cov cai
Uniform qauv: Zoo dua qhov sib xws thiab cov khoom sib xws
Kev ntsuas siab dua: Feem ntau teev rau qhov tseem ceeb heev - cov ntawv thov siab
Zoo dua corrosion kuj: Tsis muaj cua sov- thaj chaw cuam tshuam uas tej zaum yuav raug corrosion
Cov qib steel nyob rau hauv EN 10216-1 Muaj feem xyuam rau cov kev siv boiler
Tus qauv muaj ob qho tsis yog{0}} alloy thiab alloy steels. Rau cov ntawv thov carbon steel boiler, cov qib tsis yog - alloy yog qhov tseem ceeb tshaj:
