PE管材的最大不圆度范围國(guó)标参考标准

PE管材的不圆度范围國(guó)标参考标准 管材的不圆度按 GB/T 8806 规定测量同一断面的最大外径和最小(xiǎo)外径, 最大外径减去最小(xiǎo)外径為(wèi)不圆度。管材的不园度在挤出时测量。 对公称直径小(xiǎo)于等于 630mm 的直管的不圆度的推荐要求见表 B1。盘管及公称外径大于 630mm 管材的不园度可(kě)由供需双方商(shāng)定。

The out of roundness range of PE pipes is in accordance with GB / T 8806. The maximum and minimum outer diameters of the same section shall be measured according to GB / T 8806. The out of roundness shall be the maximum outer diameter minus the minimum outer diameter. The out of roundness of pipe is measured during extrusion. The recommended requirements for out of roundness of straight pipes with nominal diameter less than or equal to 630mm are shown in table B1. The out of roundness of coil and pipe with nominal outer diameter greater than 630mm can be determined by both parties.
