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)SW-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）16160.41.53803808.014.010200.61.5250150612.018180.41.54004008.014.014210.61.5250100612.020200.41.542042010.014.015301.51.5250200612.025250.62.045045010.014.015380.61.5300150612.030300.64.048048010.014.020300.62.0300200612.034341.02.050050010.014.020400.82.0300250612.035351.04.0另改拔规格如下20501.02.0400250812.038381.04.055055010.040.022350.92.0400300812.040401.04.560060010.040.025400.93.75450200812.044441.04.570070010.040.025651.02.0450250812.045451.05.080080010.050.030401.03.75400300812.050501.05.090090010.050.030451.03.75400350812.060601.55.01000100010.050.030501.04.05002001012.070702.06.030601.04.55002501012.075752.06.040501.04.55003001012.080802.06.040601.05.05003501012.085852.06.040801.55.05004001012.095952.08.0401002.05.05004501012.01001002.08.050602.05.0改拔规格如下1201204.08.050802.05.06002001028.01501506.010.0501002.08.06004001028.01801806.012.060802.06.06005001028.02002006.012.0801002.08.08004001028.02202206.014.0120602.510.08006001028.02502506.014.0120802.510.08007001028.02802806.014.01501002.512.010004001028.03003008.014.01801502.512.010005001028.03203208.014.0200100412.010006001028.03503508.014.0200150412.010008001028品名规格品名规格方管20*20*0.6-2.0方管130*130*3.0-12方管25*25*0.6-2.0方管140*140*3.0-12方管30*30*0.8-3.0方管150*150*3.0-12方管40*40*0.8*4.0方管160*160*4.0-12方管50*50*1.0*5.0方管180*180*4.0-12方管60*60*1.2-6.0方管200*200*4.0-14方管70*70*2.0-6.0方管220*200*4.0-16方管75*75*2.0-6.0方管250*250*6.0-16方管80*80*2.0-8.0方管280*280*6.0-16方管90*90*2.0-8.0方管300*300*6.0-16方管100*100*2.0-12方管350*350*8.0-16方管120*120*3.0-12方管400*400*8.0-16方管125*125*3.0-14方管450*450*10*20型号 理论重量（kg/m） 型号 理论重量（kg/m）20*20*1.2 0.75 50*30*2.5 3.0225*25*1.2 0.94 50*30*3 3.640*40*2 2.29 50*32*2 2.240*40*2.5 3.02 50*35*2.5 3.3240*40*4 4.68 55*38*2 2.850*50*2.5 3.81 60*40*2.5 3.8150*50*3 4.44 60*40*3 4.4450*50*4 5.74 60*40*4 5.7460*60*2.5 4.52 70*50*4 7.0260*60*3 5.38 80*60*3 7.0960*60*4 7.02 80*60*4 8.2270*70*4 8.22 80*60*5 10.2570*70*5 10.2 90*40*2.5 5.1980*80*4 9.96 90*60*5 10.4780*80*6 13.85 100*60*3 7.3100*100*4 11.65 100*60*4 9.16100*100*8 23 100*60*5 11.53120*120*4 14.16 1
