鋼管除銹刷漆絕熱保溫計算表,,,,,,,,

管道類別,公稱直徑DN,管道外徑D（mm）,長度L（m）,保溫厚度δ（mm）,保溫層(m3),保護層(m2),除銹刷漆(m2),備注

無縫鋼管,400,426,0.00,30,0.00,0.00,0.00,此表按下式計算：1、體積（保溫層）：V=π×【D+δ（1+1×3.3％）】×δ（1+1×3.3％）（m3）；2、面積（保護層）：S=π×【D+2δ（1+1×5％）×2d1×3d2】（m2）.式中：D——管道外徑（mm）；δ——保溫層厚度（mm）；2d1——用于捆扎保溫材料的金屬線直徑或鋼帶寬度（取定16＃線：2d1＝0.0032）；d2——防潮層厚度（取定350克油氈紙，3d2＝0.005）；3.3％、5％——保溫材料允許超厚系數；本計算式系根據國標GBJ－235－82和部標HGJ－215－80標準；絕熱厚度允許偏差：≤5％～8％加權平均取定。
