方矩形钢管理论重量计算表

1、       方矩形钢管理论重量计算表正方形和长方形(矩形)截面碳钢钢管:每米重量单位: kg/m(千克/米) & lb/ft(磅/英尺) 方便常用方矩管计算公式为：(长+宽)×2÷3.14-厚度×厚度×0.02466= kg/m 公式二:kg/m = (Oc - 4Wt) * Wt * 0.00785其中：Oc是钢管外周长，Wt是钢管壁厚；    正方形Oc=4*a      

2、           长方形Oc=2a+2b a,b是边长通俗的解释为：4x壁厚x(边长-壁厚)x7.85  其中，方管边长和壁厚都以毫米为单位，直接把数值代入上述公式，得出即为每米方管的重量，以克为单位。  如30x30x2.5毫米的方管，按上述公式即可算出其每米重量为：  4x2.5x(30-2.5)x7.85=275x7.85=2158.75克，即约2.16公斤 当壁厚和边长都以毫米为单位时，4x壁厚x(边长-壁厚)算出的是每米长度方管的体

3、积，以立方厘米为单位，再乘以铁的比重每立方厘米7.85克，得出即为每米方管以克为单位的重量。方钢边长a mm(型号)理论重量kg/m方钢边长a mm(型号)理论重量kg/m方钢方钢5.50.237131.3360.283141.546.50.332151.7770.385162.0180.502172.2790.636182.54100.785192.83* 110.95203.14121.13213.46223.86331.2* 234.15* 6533.2244.52* 6836.3254.917038.5265.317544.2* 275.728050.2286.158556.7* 29
