Feature of PP-R Fiber Pipe
1.Lower coefficient of linear expansion---less than 0.045mm/mk, which is only 30% of PPR Pipe's, and this is similar with PP-R stable composite pipe;
2. Good rigidity and stability;
3. High impact resistance in low temperature;
4. High pressure resistance, which is 25% more than PPR pipe in the same condition;
5. Link by welding, safe and reliable;
6. Inner layer is pure PP-R material with smooth surface.
