PVC管材有很好的力学性能，且具备良好的耐腐蚀性，重量轻，安装方便，无需维护，用于家装排水系统，是好的选择。也可使用PVC固定或半固定灌溉系统，可节水50%左右，而且能提高产量，大大节约灌喷设施的造价。

PVC pipe has good mechanical properties, excellent corrosion resistance, light weight, easy installation and no maintenance. It is the only choice for domestic drainage devices. PVC fixed or semi fixed irrigation device can also be used, which can s***e water by about 50%, and increase the output and greatly s***e the cost of irrigation and spraying facilities.

ppr热膨胀性能

我们会使用冷水，也会使用热水;我们生活的环境也会发生一年的四季变化。所以的水管材料不应该是导热材料，应该是热膨胀系数较小，对环境温度和使用温度适应性较强。热膨胀系数过高也是漏水的原因之一。

Thermal expansion properties of PPR

We use cold water and hot water; The environment we live in also changes in four season of the year. So the water pipe material should not be thermal conductivity material, should be the coefficient of thermal expansion is ***all, the environmental temperature and use temperature adaptability is strong. High coefficient of thermal expansion is also one of the reason for water leakage.
