PP-R труб

1)Has a layer of three layers,outside is NANO Modified PPR layer,the mid layer is high fiber enhanced composite material layer while the inner is made of IONPURE Ag-type inorganic antibacterial layer 2)This kind of pipe has higher stength,higher tenecity,higher rigidity and lower linear expansion coefficient. 3)Greatly reduced linear expansion coefficient,30% of that of PPR,which is close to that of the stable composite pipe 4)It can bear 25% more pressure load than PPR under the same service condition 5)Excellent resistance to high temperature,it can be used in 90 degree for long time
