冷热水管的区别主要在耐受压力的方面;冷水管的耐受压力是1.25或1.6兆帕，热水管的耐受压力是2.0或2.5兆帕。冷水管与热水管耐受压力不同，壁厚不同，价格也不同，热水管要比冷水管的管壁厚，价钱要贵。热水管上标识有红线，另外，如果同种规格的管子比较壁厚也能区分冷热水管。

release释怀 07-22 11:44

从ppr外径规格来算，常见的家装ppr规格有：20、25、32mm等规格。S3.2和S2.5热水管，这两种是家庭用的热水管道，有PPR标准型和PPR抗菌型的，是用于暖气的话就用标准型PPR就可以了。S4和S5为冷热水管(PPR水管是分冷热水管的，管壁厚薄不一样，冷水管不能用做热水管，分辨冷热水管的简便方法是热水管上有一条红线标记，现在家装中很多都采用全部使用热水管。)。PPR管的管径：家装中用到的主要是20mm，25mm两种(分别俗称4分管、6分管),其中4分管用到的更多些。一般总管用6分管，分管用4分管。
