  无缝钢管一公斤多少钱，一米多少公斤，一米多重？ 

钢管理论重量计算公式：（包括无缝钢管，焊管）单位：kg/m W= 0.02466 ×S （D - S ） D= 外径 S= 壁厚      

 举例：外径为 219mm 壁厚 12mm 的无缝钢管，求每m 重量。每m 重量= 0.02466 ×12×（219-12）= 61.259kg   单位：Kg/m 壁 厚    外 径 3 3.5 4 4.5 5 5.5 6  32 2.146 2.460 2.762 3.052 3.329 3.594 3.847 38 2.589 2.978 3.354 3.718 4.069 4.408 4.735 42 2.885 3.323 3.749 4.162 4.562 4.951 5.327 45 3.107 3.582 4.044 4.495 4.932 5.358 5.771 50 3.477 4.014 4.538 5.049 5.549 6.036 6.511 54 3.773 4.359 4.932 5.493 6.042 6.578 7.103 57 3.995 4.618 5.228 5.826 6.412 6.985 7.546 60  4.217 4.877 5.524  6.159 6.782 7.392 7.990 63.5 4.476 5.179 5.869 6.548 7.214 7.867 8.508 68 4.809 5.567 6.313 7.047 7.768 8.477 9.174 70 4.957 5.740 6.511 7.269 8.015 8.749 9.470 73 5.179 5.999 6.807 7.602 8.385 9.156 9.914 76 5.401 6.258 7.103 7.935 8.755  9.563 10.358  89 6.363 7.380 8.385  9.378  10.358 11.326 12.281  108  7.768 9.020 10.259 11.486 12.701 13.903 15.093  133 11.178 12.725 14.261 15.783 17.294 18.792   159 13.422 15.290 17.146 18.989 20.821 22.639   219 18.601 21.209 23.805 26.388 28.959 31.517   273 23.262 26.536 29.797 33.046 36.283 39.508   325 27.750 31.665 35.568 39.458 43.337 47.202   355 38.897 43.158 47.406 51.641       377 41.339 45.871 50.390 54.897       426 46.777 51.913 57.036 62.147        450               480               530                          630
