热塑性塑料管.通用管壁厚度表

[中文适用范围]： 本文件规定了热塑性塑料管材的公称壁厚en 和公称外径an 之间的关系。 它适用于沿管材整个长度具有恒定圆形横截面的实壁热塑性塑料管材，无论其制造方法、成分或预期用途如何。 注：沿管材全长具有恒定圆形截面的管材俗称内外表面光滑的管材， [外文原描述]： ISO 4065:2018 specifies the relationship between the nominal wall thickness e n and the nominal outside diameter d n of thermoplastics pipes. ISO 4065:2018 is applicable to solid-wall thermoplastics pipes of constant circular cross-section along the whole length of the pipe, whatever their method of manufacture, their composition or their intended application. NOTE Pipes with constant circular cross-section along the whole length of the pipe are commonly known as pipes with smooth external and internal surfaces.
