如何選擇優質的直縫焊管?

日期:2020-03-02

選擇直縫鋼管時,首先要注意材質。當我們檢查貨物時,我們必須首先確定材料是否合格。

如何選擇優質的直縫焊管

第二步是查看直縫鋼管的壁厚是否達到要求的壁厚。公差是否在國家要求范圍內。

第三,取決于鋼管的表面,是否生銹和生銹的程度。通常,黃銹是沒有問題的。通常,黃銹是一層漂浮的銹,而紅銹則稍微嚴重一些,但也可以在退火后用于一些不太嚴格的項目中。使用,但如果是黑銹,則表示該管只能出售廢鐵。

另外,我們還需要查看鋼管表面是否有油,因為在生產過程中直縫鋼管可能會在裝置上沾上油。最后,我們需要查看管道兩端的橫截面是圓形還是具有不規則的擠壓。同時尋找故障。如果鋼管通過上述嚴格的檢查方法,則表明鋼管合格。
