管道保温用料计算.doc

管道保温用料计算管道保温材料工程量可按以下公式进行计算；保温层工程量计算：V=100（DW+3.3%）（+3.3%）保温层外防潮层或保护层工程量计算：S=100（DW+2+25%+2d+3d）式中 V 保温材料体积（m）； S 防潮层或保护层面积（m）； DW 管道外径（m）； 保温层厚度（m）； d 用于捆扎保温材料的金属线直径或钢带厚度（m），当取16#铁线时，2d=0.0032； d 防潮层或保温层厚度（m），当取350g油毡纸时，3d=0.005.以上两式中的系数3.3%及5%，系根据保温材料允许超厚系数加权平均取定。为了只用方便，现将常用管道保温材料工程量列于表2012中。 表2012 无缝钢管保温材料工程量计算表（100m）管道外径D W（mm）保 温 层 厚 度（mm） 02025体积面积体积面积体积面积226.910.2822.680.3925.98288.790.3224.570.4327.873210.10.3425.820.4629.123811.930.3827.710.5231.014514.130.4129.910.5833.215717.90.5133.660.6736.967623.860.6339.630.8342.928927.950.7143.710.9347.0110833.910.8449.671.0852.9711435.800.8851.561.1454.8613348.101.0057.521.2960.8215950.01.1765.691.5065.8821968.81.5684.531.9887.82管道外径D W（mm）保 温 层 厚 度（mm） 303540体积面积体积面积体积面积220.5229.280.6632.580.8235.88280.5831.160.7334.460.9037.76320.6132.420.7735.720.9639.02380.6734.310.8537.601.0340.90450.7436.510.9239.801.1243.10570.8640.251.0543.551.2746.86761.0446.221.2749.521.5252.81891.1750.301.4353.601.6956.901081.3556.271.6359.571.9462.861141.4258.151.761.452.0164.751331.5964.121.9268.042.2670.711591.8572.282.2175.582.6078.882192.4391.122.8994.423.3897.72管道外径D W（mm）保 温 层 厚 度（mm） 455055体积面积体积面积体积面积221.0039.181.242.471.445.77281.0841.061.2944.361.5247.66321.1442.321.3545.621.5848.91381.2344.201.4647.501.6950.80451.3346.401.5749.701.8253.00571.5150.151.7753.442.0456.74761.7956.112.0759.412.3762.71891.9760.192.2863.492.6066.701082.2566.162.5769.462.9472.751142.3468.042.6971.343.0574.641332.6274.013.0077.313.3980.601593.0082.173.4285.473.8588.772193.87101.014.39104.314.97107.61管道外径D W（mm）保 温 层 厚 度（mm） 02025体积面积体积面积体积面积27385.801.90101.482.43104.78325102.012.24117.812.84121.11377118.402.58134.213.26137.51426133.802.90149.603.67152.90478150.203.23165.944.09169.24525.6165.123.54180.894.47184.19630197.704.22213.695.32216.99660.4207.404.42223.245.57226.51726228.084.84243.856.09247.15820257.605.45273.386.86276.68920289.036.11304.837.68308.101020.00320.446.76336.218.48338.511222.00383.278.07399.6710.12402.97管道外径D W（mm）保 温 层 厚 度（mm） 303540体积面积体积面积体积面积2732.95108.083.51111.384.08114.673253.46124.414.10127.714.75131.003773.98140.814.69144.105.43147.404264.45156.205.25159.506.06162.804784.96172.545.84175.836.75179.13525.65.42187.006.38190.797.35194.096306.44220.297.56223.598.72226.89660.46.74229.847.91233.149.11236.447267.37250.458.66253.759.96257.058208.28279.929.72283.2810.66286.549209.26311.3410.86314.6912.48317.991020.0010.24342.8111.99346.1113.82349.411222.0012.20406.2714.29409.5716.40412.87管道外径D W（mm）保 温 层 厚 度（mm） 455055体积面积体积面积体积面积2734.66117.975.27121.275.89124.563255.42134.306.11137.596.81140.893776.19150.706.95154.007.75157.304266.90166.107.75169.398.62172.694787.65182.438.59185.739.54189.02525.68.36197.399.37200.6810.39203.986309.88230.1811.06233.4312.26236.78660.410.32239.7311.47243.0312.80246.3372611.28260.3412.62263.6413.98266.948201
