无缝钢管重量.doc

108的无缝钢管如何计算壁厚 长度1米如何计算重量108的无缝钢管如何计算壁厚-要先知道每米重量才能计算;长度1米如何计算重量-要先知道壁厚才能计算;总之,无缝钢管每米重量、外径、壁厚三个要知道两个，才能计算另一个。无缝钢管理论重量计算公式：无缝钢管 W=0.0246615(D-S)*S W:钢管理论重量 kg/m D :钢管公称外径 mm S :钢管公称壁厚 mm 常用钢材钢管重量理论计算方法常用钢材钢管重量理论计算方法 钢材理论重量计算 钢的密度为： 7.85g/cm3 钢材理论重量计算的计量单位为公斤（ kg ）。其基本公式为：W（重量，kg ）=F(断面积 mm2)L(长度，m)(密度，g/cm3)1/1000各种钢材理论重量计算公式如下： 名称（单位） 计算公式 符号意义 计算举例圆钢 盘条（kg/m） W= 0.006165 dd d = 直径mm
