PPR-FB-PPR combines advantages both PP-R pipe and FRPP pipe. It is composite pipe of three layers: PPR/glass fiber/PPR. inside and outside layers of which are made of excellent PP-R material; middle layer is the new material mixed glass fiber and pp-r material.

Advantages:                                                  
High pressure resistance, High rigidity that not easy to change its shape.
Low linear expansion coefficient ,only 1/3 of the plain PP-R pipes.
Excellent thermal stability and frostbite prevent bring it a working temperature up to 95°C.
Low longitudinal shrinkage factor
Long lifespan up to 50 years.
