用户可以根据PPR管材的耐高温性与耐高压性来参考，PPR原料的熔点温度较高，而原料中掺入其它杂质则会致使PPR管材的熔点就会下降。
一、看外观：PPR管管子内外壁光滑。
二、手感：好的PPR水管质感细腻。
三、原料：PPR水管采用进口PPR原料
四．看热熔焊接：好的PPR水管热熔焊接时是***无味的白烟，劣质PPR水管是冒***的黑烟、呛人。
ppr管的耐水性：
耐水管件的连接和防渗漏性能也是应该注意的。由于PPR管生产线经过对该管材特点的分析，设计生产了的剥铝工具，将铝层及PPR外层剥离掉，同样可以采用热熔承插的方法进行连接，消除了普通PPR管用铜管件连接容易渗漏的引患，更好的是管道实现其耐水性能。
Water resistance of PPR pipe:The connection and leakage resistance of water resistant pipe fittings should also be paid attention to. Because of the analysis of the characteristics of the pipe， the production of the stripping tool is designed and produced. The aluminum layer and the outer layer of PPR can be separated. The hot melt socket can be used to connect the pipe. The common copper pipe used in PPR pipe is easy to leak， and the better is to realize the water resistance of the pipe.
装修中，PVC管业生产，常听工人说4分管、6分管，自己却不知道是什么意思？其实这指的是管子的外径，4分管外径20mm，6分管外径25mm。选择哪种管，要看水管的外径来决定。管4分管，PVC管业电话，只能使用4分管。管是6分管，西城区PVC管业，使用6分管、4分管都可以。另外，水管上也会标注20*2.8、25*4.2，PVC管业品牌，前面的20、25就是指管子外径，而后面的2.8、4.2则指水管的壁厚。一般管壁越厚，水管就越耐用。
Parameters of PPR tube
Decoration， often listen to workers say 4 in charge， 6 in charge， but do not know what it means? In fact， this refers to the outer diameter of the pipe. The outer diameter of 4 branch pipes is 20 mm， and that of 6 branch pipes is 25 mm. Which kind of pipe to choose depends on the outer diameter of the pipe. Only four branches can be used. The management is divided into 6 branches. It is OK to use 6 branches or 4 branches. In addition， 20 * 2.8 and 25 * 4.2 will also be marked on the water pipe. The front 20 and 25 refer to the outer diameter of the pipe， while the back 2.8 and 4.2 refer to the wall thickness of the water pipe. Generally， the thicker the pipe wall is， the more durable the water pipe is.
