常用鋼制管件（彎頭、三通、異 徑管、管帽）理論重量體積表霸期管株爨諭常用管件產品重量 / 體積表使用說明1 本表的管件重量依據(jù) ASME B16.9/ASME B16.11 等相關規(guī)范使用的外徑和壁厚進行計算，計算中適當考慮了工藝選料和制造情況對產品重量的影響 （如厚度補償 ）；故此表所列重量為單件產品的近似凈重，供參考表格中管表號帶 S 的為不銹鋼管件重量，其余為碳鋼重量；在查閱不銹鋼管件重量時應注意同一管表號的壁厚值碳鋼與不銹鋼可能不同2 90 °彎頭重量計算公式： W=9.685*10-6R（D2-d2）式中： W — 90 °彎頭重量， kg ；R — 彎頭的曲率半徑（結構尺寸） ， mm；D — 彎頭外徑， mm；d — 彎頭內徑， mm彎頭重量公式中采用碳鋼比重，即 7.85kg/dm 3計算45180 °彎頭的重量分別按 90 °彎頭重量的 1/2 和 2 倍計算3 鋼管重量計算公式： W=0.02466T(D-T)式中： W — 鋼管每米長度的重量， kg/m；T — 鋼管壁厚， mm；D — 鋼管外徑， mm鋼管重量公式中采用碳鋼比重， 即 7.85kg/dm 3計算； 奧氏體不銹鋼管的重量為上式重量的 1.015 倍。

4 對焊管件的重量表中列出的為常用規(guī)格的重量，對于未列入表中的同一公稱通徑、不同壁厚的產品重量，可用估算公式進行重量的大致估算： Q=Wt/T式中： Q — 估算的對焊管件重量， kg ；W — 表中同一公稱通徑已列出壁厚的產品重量， kg；t — 估算的對焊管件的產品壁厚值， mm；T — 表中同一公稱通徑已列出壁厚的產品壁厚值， mm5本表所列體積為單件產品外部輪廓體積并考慮了裝箱時所占的空間，即表中 所示的近似體積為單件產品所占包裝物的近似體積， 供參考；使用時應注意套裝時體積的計算以及小件產品體積是否需要考慮等因素彎頭理論重量表2012年09月01日更新發(fā)布:直 徑壁厚（mm）mm33.544.555.566.5789101112131415161718192022242526283018~220.060.070.070.090.10---------說明：1、180彎頭按2倍計算,45°彎頭按1/2計算；2、R=1.0DN的彎頭按2/3計算；3、表中未列出壁厚的重量，可取之相近的兩個重量計算的平均彳S;4、90彎頭計算公式：0.0387*S（D-S）R/1000式中：5=壁厚（mm）、D=外徑（mm）、R=彎曲半徑（mm）250.100.110.120.140.150.160.17-------270.110.120.140.150.160.170.18-------320.130.150.160.180.200.210.230.24------340.140.150.180.200.210.230.250.26------380.200.220.250.280.310.330.360.380.40-----420.220.250.280.310.340.370.400.420.46-----450.290.340.380.420.460.500.540.580.620.69----480.310.360.410.450.500.540.590.630.690.72----510.330.390.440.490.530.580.630.670.720.80----570.480.540.620.700.760.830.900.981.021.151.271.38--600.500.580.660.730.810.880.951.021.091.221.351.47--730.800.921.051.171.291.411.531.641.751.972.192.392.592.78壁厚（mm）760.820.961.091.221.341.471.611.741.832.062.292.502.712.911314151617181920222425262830891.201.391.571.771.952.132.312.492.653.013.343.673.994.29--------------1081.852.152.452.743.033.323.603.884.164.715.245.766.286.787.267.74------------1141.962.282.592.903.213.513.814.114.414.995.566.126.667.207.728.24------------1272.743.183.624.064.494.925.345.766.187.007.818.609.3910.210.911.612.413.113.814.4--------1332.873.333.804.254.715.165.616.056.497.368.349.059.8710.711.512.113.013.814.515.2--------1403.023.514.004.494.975.645.916.386.857.778.679.5610.411.312.113.013.814.615.416.2--------159--5.496.166.827.488.148.789.4310.712.013.214.415.616.818.019.120.321.422.523.624.626.7-----168--5.816.527.227.928.619.309.9911.312.714.015.316.617.919.120.321.622.723.925.126.228.5-----219----12.613.915.116.317.520.022.324.727.029.331.633.936.138.340.542.744.947.051.256.358.362.165.9273----19.821.723.625.527.531.335.038.842.546.249.953.556.160.764.267.771.274.681.588.191.594.7101108325----28.331.133.936.639.444.950.355.761.166.471.777.082.287.492.697.7103108118128133138147157355----36.139.743.246.750.357.364.371.278.184.991.798.5105112119125132138151164170177189201377----38.442.245.949.753.460.968.375.783.190.497.6105112119126133140147161175182188202216406----47.352.056.761.365.975.284.393.5103112121130139148156165174182199217225233250266426----49.754.559.564.469.278.988.698.2108117127136146155164173183192210228237246263281457--------83.695.4107119130142153165176187199210221232254276287298319340480--------87.9100113125137149161173185197209221233244267290302313336358508--------103118132147161176190204218232246260274288315343356370396423529--------108123138153168183198213227242257271286300。
