管道固定后才能使用中，管材不会因为水压而造成共振现象的发生。PPR水管在固定式，要使用管卡固定，对于管材间距在500mm左右，PVC管材厂家，外径在25mm以下的管道，其在管道的终端10厘米处及水表处等地亦要设置管卡。
PPR pipe fixing
The pipe can not be used until it is fixed. The pipe will not cause resonance due to water pressure. PPR water pipe is fixed with pipe clamp. For pipes with pipe spacing of 500mm and outer diameter less than 25mm， pipe clamps shall be set at the end of pipeline at 10 cm and water meter.
管道壁厚的增加直接带来的性能的提升，比如：工作压力增大，刚性增强，线性膨胀系数降低，PVC管材电话，耐温性能提高等等。
The increase of pipe wall thickness directly improves the performance， such as the increase of working pressure， the increase of rigidity， the decrease of linear expansion coefficient， the improvement of temperature resistance and so on.
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，PVC管材生产，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，PVC管材，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， which can resist the corrosion of chemical elements in water. At the same time， its surface can ***oid the formation of scale， which can promote the tran***ission of water more clean and sanitary.
