Yuav ua li cas xam 2507 Stainless Hlau Yeeb Nkab Nqe ib 'meter'?
Thaum muab piv rau 2507 duplex stainless hlau yeeb nkab nqi, cov neeg yuav khoom yuav tsum suav cov theoretical yeeb nkab qhov hnyav ib 'meter' ua ntej muab piv cov lus hais. Cov yeeb nkab hnyav feem ntau nyob ntawm sab nraud (OD), phab ntsa thickness (WT), thiab cov khoom siv ntom ntom. Thaum paub qhov ntsuas qhov hnyav, tus nqi ib 'meter' tuaj yeem xam los ntawm tus nqi nqe ib kilogram.
2507 Stainless hlau yeeb nkab hnyav Formula
Rau ib puag ncig yeeb nkab, kwv yees qhov hnyav theoretical yog:Qhov hnyav (kg / m)=0.02450 × WT × (OD − WT)
Qhov twg:
OD=sab nraud txoj kab uas hla hauv mm
WT=phab ntsa thickness hauv mm
0.02450=kwv yees suav tas li raws li qhov ceev ntawm 7.8 g/cm³
Qhov hnyav=theoretical hnyav hauv kg ib 'meter'
Cov mis no haum rau kev kwv yees tus nqi ua ntej. Actual weight may vary according to the material density, dimensional tolerances, manufacturing method, and agreed commercial weighing basis.
Piv txwv li: xam qhov hnyav ntawm 2507 yeeb nkab
Xav tias qhov xav tau Super Duplex 2507 yeeb nkab muaj qhov ntev hauv qab no:
