厚壁無縫鋼管理論計算公式誰知道？尺寸偏差及理論重量！
無縫鋼管廠介紹，厚壁無縫鋼管的理論計算公式：(外徑壁厚)×壁厚×0.02466=KG/M(每米的重量) 例：325*10的無縫鋼管計算方法， (32510)*10*0.02466=77.679Kg 厚壁無縫鋼管尺寸及允許偏差偏差等級標準化外徑允許偏差D1±1.5%，最小±0.75mmD2±1.0%。最小±0.50mmD3±0.75%．最小±0.30mmD4±0.50%。最小±0.10mm 厚壁無縫鋼管理論重量單位：Kg/m壁厚外徑6.5788.591012324.088385.049425.691456.172506.9737.4238.2868.699547.6148.1149.0759.538578.0958.6329.66710.167608.5769.14910.25910.79663.59.1379.75410.9511.529689.85810.5311.83812.4737010.17910.87612.23212.89213.53914.79717.1647310.6611.39412.82413.52114.20515.53718.0527611.14111.91213.41614.1514.87116.27718.948913.22514.15615.98116.87517.75619.48322.78710816.2717.43619.72920.85821.97324.16828.4113320.27821.75124.66226.09827.52230.33435.80915924.44626.2429.79131.54833.29336.74643.50321934.06436.59841.62944.12646.6151.54361.25927342.7245.9252.28355.44558.59664.8677.2432551.05654.89762.54266.34670.13777.68492.62935555.86560.07668.4672.63476.79685.082101.50737759.39163.87372.80177.24681.67990.508108.01842667.24672.33282.46887.51892.555102.592122.51945071.09376.47587.20392.54997.882108.511129.62148075.90281.65493.12298.837104.54115.909138.49953083.91790.286102.987109.319115.638128.24153.29663099.947107.549122.716130.281137.833152.902182.89
