方管理论重量表及计算公式4x壁厚x（边长-壁厚）x7.85 其中，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 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 为单位的重量焊接管理论重量计算公式W=0.02466（D-S）S W----为理论重量D-----为公 称直径S——为壁厚单位为mm方管规格（mm）矩型管规格（mm）16x16x0.4-1.5380x380x8-1410x20x0.6-1.5250x150x6-1218x18x0.4-1.5400x400x8-1414x21x0.6-1.5250x100x6-1220x20x0.4-1.5420x420x10-1415x30x1.5-1.5250x200x6-1225x25x0.6-2450x450x10-1415x38x0.6-1.5300x150x6-1230x30x0.6-4480x480x10-1420x30x0.6-2300x200x6-1234x34x1-2500x500x10-1420x40x0.8-2300x250x6-1235x35x1-420x50x1-2400x250x8-1238x38x1-4另改拔规格如下22x35x0.9-2400x300x8-1240x40x1-4.5550x550x10-4025x40x0.9-3.75450x200x8-1244x44x1-4.5600x600x10-4025x65x1-2450x250x8-1245x45x1-5700x700x10-4030x40x1-3.75400x300x8-1250x50x1-5800x800x10-5030x45x1-3.75400x350x8-1260x60x1.5-5900x900x10-5030x50x1-4500x200x10-1270x70x2-61000x1000x10-5030x60x1-4.5500x250x10-1275x75x2-640x50x1-4.5500x300x10-1280x80x2-640x60x1-5500x350x10-1285x85x2-640x80x1.5-5500x400x10-1295x95x2-840x100x2~5500x450x10-12100x100x2-850x60x2-5改拔规格如下120x120x4-850x80x2-5600x200x10-28150x150x6-1050x100x2-8600x400x10-28180x180x6-1260x80x2-6600x500x10-28200x200x6-1280x100x2-8800x400x10-28220x220x6-14120x60x2.5-10800x600x10-28250x250x6-14120x80x2.5-10800x700x10-28280x280x6-14150x100x2.5-121000x400x10-28300x300x8-14180x150x2.5-121000x500x10-28320x320x8-14200x100x4-121000x600x10-28350x350x8-14200x150x4-121000x800x10-28型号重量Kg型号重量Kg20*20*1.20.7550*30*2.53.0225*25*1.20.9450*30*33.640*40*22.2950*32*22.240*40*2.53.0250*35*2.53.3240*40*44.6855*38*22.850*50*2.53.8160*40*2.53.8150*50*34.4460*40*34.4450*50*45.7460*40*45.7460*60*2.54.5270*50*47.0260*60*35.3880*60*37.0960*60*47.0280*60*48.2270*70*48.2280*60*510.2570*70*510.290*40*2.55.1980*80*49.9690*60*510.4780*80*613.85100*60*37.3100*100*411.65100*60*49.16100*100*823100*60*511.53120*120*414.16100*60*4.514.41160*160*4.519.2160*80*4.515.84220*80*627.1。
