同种规格的PPR热水管壁厚要比冷水管的厚，PPR水管，简单举例：D25×2.3 D25×2.8 D25×3.5 D25×4.2 这里列举的是外径为25MM的PPR管所对应的四种不同规格，前面两种为冷水管，后面两种为热水管，因此可以非常明显的看出，冷水管的壁厚要小于热水管。

The wall thickness of PPR hot water pipe of the same specification is thicker than that of cold water pipe. Simple example: D25 × 2.3 D25 × 2.8 D25 × 3.5 D25 × 4.2 here are four different norms of PPR pipe with outer diameter of 25 mm. The first two are cold water pipes and the latter two are hot water pipes. Therefore，ppr水管安装， it is very clear that the wall thickness of cold water pipe is ***aller than that of hot water pipe.
