管道保溫用料計(jì)算

1、管道保溫用料計(jì)算管道保溫材料工程量可按以下公式進(jìn)行計(jì)算；保溫層工程量計(jì)算：V=100（DW+×3.3%）×（+×3.3%）保溫層外防潮層或保護(hù)層工程量計(jì)算：S=100（DW+2+2×5%+2d+3d）式中 V 保溫材料體積（m）； S 防潮層或保護(hù)層面積（m）； DW 管道外徑（m）； 保溫層厚度（m）； d 用于捆扎保溫材料的金屬線直徑或鋼帶厚度（m），當(dāng)取16#鐵線時(shí)，2d=0.0032； d 防潮層或保溫層厚度（m），當(dāng)取350g油氈紙時(shí)，3d=0.005.以上兩式中的系數(shù)3.3%及5%，系根據(jù)保溫材料允許超厚系數(shù)加權(quán)平均取定。為了只用方便，現(xiàn)將常
