螺旋管一噸價格

日期:2020-08-13

厚壁螺旋焊管在承受內壓時,通常在管壁上產生兩種主要應力,即徑向應力δY和軸向應力δX。焊縫處合成應力δ=δY(l/4sin2α+cos2α)1/2,其中,α為螺旋焊管焊縫的螺旋角。

當螺旋焊縫附近存在與之相平行的缺陷時,由于螺旋焊縫受力較小,故其擴展的危險性不如直焊縫大。 由于徑向應力是存在于鋼管上的大應力,所以焊縫處于垂直應力這一方向時承受大載荷。

大口徑螺旋鋼管具有超高的性價比和穩定性,是其它任何管道無法比擬的,螺旋焊接鋼管在直徑和壁厚的尺度標準范圍上有更大的靈活性,尤其在出產高鋼級厚壁管,是中小口徑厚壁管方面,有其他工藝無法比擬的優勢,可滿意用戶在螺旋鋼管標準方面更多的要求。
