,,,,方矩形鋼管理論重量計(jì)算表：,,,,,,,,

,,,,正方形和長(zhǎng)方形(矩形)截面碳鋼鋼管：每米重量單位:kg/m(千克/米)&lb/ft(磅/英尺)

,,,,,,,,

,,,,方便常用方矩管計(jì)算公式為：(長(zhǎng)+寬)×2÷3.14-厚度×厚度×0.02466=kg/m,,,,,,,,

,,,,

公式二:kg/m=(Oc-4Wt)*Wt*0.00785,,,,,,,,

,,,,"其中：Oc是鋼管外周長(zhǎng)，Wt是鋼管壁厚；

正方形Oc=4*a

；

長(zhǎng)方形Oc=2a+2ba,b是邊長(zhǎng)",,,,,,,,

,,,,通俗的解釋為：4x壁厚x(邊長(zhǎng)-壁厚)x7.85

,,,,,,,,

,,,,,,,,,,,,,

,,,,其中，方管邊長(zhǎng)和壁厚都以毫米為單位，直接把數(shù)值代入上述公式，得出即為每米方管的重量，以克為單位。

,,,,,,,,

,,,,,,,,,,,,,

,,,,如30x30x2.5毫米的方管，按上述公式即可算出其每米重量為：

,,,,,,,,

,,,,,,,,,,,,,

,,,,4x2.5x(30-2.5)x7.85=275x7.85=2158.7
