FR-PPR высокая производительность стекловолокна композитные трубы

FR-PPR high performance fiberglass composite pipe is three-layer structured. The outer and inner sides are made of PP-R material while the middle layer is made of fiberglass composite material.The inner layer PP-R material ensures hygienic performance of the pipe while the middle layer helps to strengthen pipe and reduce linear expansion coefficient.The outer layer PP-R facilitates hot-malt socket connection between the pipe and the traditional PP-R pipesfeatures high strength,high toughness,high stiffness and low linear expansion coefficient,which fill in the gap for application of ordinary PP-R in vertical pipe,visible installation pipe and hot water pipe ,It is an idea improvement from and useful supplement for PP-R pipe.
