螺旋鋼管理論重量表
螺旋鋼管是以帶鋼卷板為原材料,經(jīng)常溫?cái)D壓成型,以自動(dòng)雙絲雙面埋弧焊工藝焊接而成的螺旋縫鋼管。螺旋鋼管將帶鋼送入焊管機(jī)組,經(jīng)多道軋輥滾壓,帶鋼逐漸卷起,形成有開口間隙的圓形管坯,調(diào)整擠壓輥的壓下量,使焊縫間隙控制在1~3mm,并使焊口兩端齊平。

螺旋焊管的每米理論重量計(jì)算公式
螺旋焊管交貨時(shí)分為按實(shí)際重量交貨或按理論重量交貨實(shí)際重量--交貨時(shí),其產(chǎn)品重量是按稱重(過磅)重量交貨;理論重量--交貨時(shí),其產(chǎn)品重量是按鋼材公稱尺寸計(jì)算得出的重量。其計(jì)算公式如下(要求按理論重量交貨者,需在合同中注明):螺旋焊管每米的理論重量計(jì)算公式:W=0.0246615(D-S)S+0.5式中:W--螺旋焊管每米理論重量,kg/m;D--螺旋焊管的公稱外徑,mm;S--螺旋焊管的公稱壁厚,mm。相關(guān)閱讀- 12-06焊管的品質(zhì),價(jià)錢是一方面如何挑選
