Glass fiber PP-R (abbreviated as FR/PP-R) pipe is a high-performance pipe produced by multi-layer co-extrusion through special technology and equipment, low temperature and high speed.
On the basis of maintaining the advantages and basis of the original PP-R product, this product also has the following major characteristics:
1. The coefficient of linear expansion is only about 20~30% of ordinary PP-R products; it completely solves the problem of expansion and contraction of plastic pipes.
2. The rigidity of the pipe is enhanced to prevent the sagging of the pipe, and at the same time, the density and number of fixed support points are reduced, thereby reducing the overall cost of the project.
3. The pressure resistance level is higher, and the service life is longer under the usual design vibration force.
4. Better high temperature resistance, obvious effect of energy saving and consumption reduction; FR/PP-R is used in hot water systems, and the normal use temperature can reach 95~100 °C, which not only increases the temperature of the medium used, but also reduces the thermal insulation material. Thickness, its comprehensive cost is lower.
5. Large water flow: Under the same level of pressure, the wall thickness of the FR/PP-R pipe increases the inner diameter of the pipe, thereby increasing the water flow (increase by 20%).
6. The problem of oxygen permeability of the pipeline is solved. The inner surface directly in contact with water is hygienic, non-toxic, and has good sealing performance, and will not form water moss. The composition of the middle layer of the glass fiber reinforced FR/PP-R pipe completely isolates the outside air from infiltrating the pipe, thereby inhibiting the growth of algae and keeping the water fresh and pure.
