the reinforced glass fiber composite ppr pipe, the outer layer is ppr, the middle layer is glass fiber, the inner layer is ppr. PN=1.*5, PN=1.6, PN=2.0, PN=2.5 Compared to common ppr pipe, the glass fiber reinforced pipe is better in many performances, such as heating resistance, overpressure resistance, and lower in expansion coinficience which is just *0% of the common ppr pipe. It has the longer working life, and higher strenghth, and better shock resistance to prevent the pipe from hanging down. It's the ideal choice of solar energy, heat energy cyclic system, warming system and water supplying some pieces of 4m pipes in a woven bag ISO***1:***8
