In addition to the wall thickness， we can also distinguish from the color marking on the outer wall of PPR pipe. Color marking is also called coextrusion. The PPR hot water pipe is marked with red color marking， the PPR cold water pipe is marked with blue color marking， and there are also manufacturers who do not need any color marking for PPR cold water pipe. 

管材管道在使用过程中热胀冷缩现象也是不可避免的。选自耐水性材料的PPR管道刚性增强，水平布管时不易下垂，增加了管线的美观，PVC管业厂家，管道的弯曲回弹性得到提高，在高温下时仍保持外形的稳定。

The phenomenon of heat expansion and cold contraction is inevitable in the use of pipe. The PPR pipe selected from water-resistant material has stronger rigidity， and it is not easy to sag during horizontal pipe laying， which increases the appearance of the pipeline，绍兴PVC管业， improves the bending resilience of the pipeline，PVC管业加工， and maintains the stability of the shape at high temperature.

根据耐腐蚀性能来参考?

具体来说，PPR管材耐腐蚀与防结垢性能则施工项目管道的基本需求，优良的PPR管材的耐化学腐蚀性能更好，其能够抵抗水中的化学元素的腐蚀，与此同时，其表面则可避免水垢的形成，以此可以促使输送的水更加洁净与卫生。

According to the corrosion resistance

Specifically，Corrosion resistance and anti scaling performance of PPR pipe are the basic requirements of building project pipeline. Excellent PPR pipe has better chemical corrosion resistance，PVC管业咨询， which can resist the corrosion of chemical elements in water. At the same time， its surface can avoid the formation of scale， which can promote the transmission of water more clean and sanitary.
