计算条件:空调水管外径为d1(mm),保温材料厚度为δ(mm),保温后管外径为d2(mm)= (d1+2δ),计算管长为l(m), d1n 为管道公称直径(mm),d1w为管外径(mm);
保温材料体积计算公式为: 每1000米长管道在不同保温厚度时所用的保温材料体积V(m3)速查表 δd1n d1w 15 20 25 32 40 50 65 80 100 125 150 200 250 300 350 400 450 500 600 700 800 900 1000 1200 21.3 26.8 33.5 42.3 48 57 73 89 108 133 159 219 273 325 377 426 478 529 630 720 820 920 1020 1220 20 2.59 2.94 3.36 3.91 4.27 4.84 5.84 6.85 8.04 9.61 11.24 15.01 18.40 21.67 24.93 28.01 31.27 34.48 40.82 46.47 52.75 59.03 65.31 77.87 25 3.64 4.07 4.59 5.28 5.73 6.44 7.69 8.95 10.44 12.40 14.44 19.15 23.39 27.48 31.56 35.41 39.49 43.49 51.42 58.48 66.33 74.18 82.03 97.73 4.83 5.35 5.98 6.81 7.35 8.20 9.70 11.21 13.00 15.36 17.80 23.46 28.54 33.44 38.34 42.96 47.85 52.66 62.17 70.65 80.07 89.49 98.91 117.75 30 6.19 6.79 7.53 8.50 9.12 10.11 11.87 13.63 15.72 18.46 21.32 27.92 33.85 39.57 45.28 50.67 56.38 61.99 73.09 82.98 93.97 104.96 115.95 137.93 35 40 7.70 8.39 9.23 10.34 11.05 12.18 14.19 16.20 18.59 21.73 25.00 32.53 39.31 45.85 52.38 58.53 65.06 71.47 84.15 95.46 108.02 120.58 133.14 158.26 45 9.37 10.15 11.09 12.34 13.14 14.41 16.67 18.94 21.62 18.79 28.83 37.30 44.94 52.28 59.63 66.56 73.90 81.11 95.38 108.10 122.23 136.36 150.49 178.75 50 11.20 12.06 13.11 14.49 15.39 16.80 19.31 21.82 24.81 28.73 32.81 42.23 50.71 58.88 67.04 74.73 82.90 90.90 106.76 120.89 136.59 152.29 167.99 199.39 55 13.18 14.13 15.29 16.81 17.79 19.34 22.11 24.87 28.15 32.47 36.96 47.32 56.65 65.63 74.61 83.07 92.05 100.86 118.30 133.85 151.11 168.38 185.65 220.19 60 15.32 16.36 17.62 19.28 20.35 22.05 25.06 28.07 31.65 36.36 41.26 52.56 62.74 72.54 82.33 91.57 101.36 110.97 130.00 146.96 165.80 184.64 203.48 241.16 65 17.62 18.74 20.11 21.90 23.07 24.90 28.17 31.43 35.31 40.41 45.72 57.97 68.99 79.60 90.21 100.22 110.83 121.24 141.85 160.22 180.63 201.04 221.45 262.27 回网友:
保温管快速计算立方:(直径+厚度)x3.145x厚度x数量
例:问保温材料体积计算表中DN65钢管,外径73,实用中DN70钢管,外径76,请问保温材料体积怎麽计
算?
答:( 0.76+0.20)x3.145x0.20x数量
