Glass fiber reinforced PPR pipes information:  Glass fiber reinforced PP-R pipes (briefly called FR/PP-R) are piping materials produced through special technology and equipment by usingmulti-layer co-extrusion, low temperature and high speed. Based on advantages of PP-R products, these products also have the following big advantages. 1. The linear expansion coefficient accounts only for about 20~30% of the ordinary PP-R products; Thoroughly solved the difficult problem ofexpansion and shrinkage ofplasticpipeline.   2. Strengthening of pipe rigidity preventing deflection of pipeline and at the same time reducing density and quantity of fixed supporting points,thus reducing comprehensive cost of the pipeline.3. Good resistance to ultraviolet radiation  4. Higher pressure resistance and longer service life under conditions of designed vibration force.
