螺旋钢管理论重量表
螺旋钢管是以带钢卷板为原材料,经常温挤压成型,以自动双丝双面埋弧焊工艺焊接而成的螺旋缝钢管。螺旋钢管将带钢送入焊管机组,经多道轧辊滚压,带钢逐渐卷起,形成有开口间隙的圆形管坯,调整挤压辊的压下量,使焊缝间隙控制在1~3mm,并使焊口两端齐平。

螺旋焊管的每米理论重量计算公式
螺旋焊管交货时分为按实际重量交货或按理论重量交货实际重量--交货时,其产品重量是按称重(过磅)重量交货;理论重量--交货时,其产品重量是按钢材公称尺寸计算得出的重量。其计算公式如下(要求按理论重量交货者,需在合同中注明):螺旋焊管每米的理论重量计算公式:W=0.0246615(D-S)S+0.5式中:W--螺旋焊管每米理论重量,kg/m;D--螺旋焊管的公称外径,mm;S--螺旋焊管的公称壁厚,mm。相关阅读- 12-06焊管的品质,价钱是一方面如何挑选
