PP R pipe Matereial: Polypropylene Size: DN 20 to 75mm Pressure Rating: 1.25Mpa, 1.6MPa, 2.0MPa, 2.5MPa Color: green, grey, white Applications: cold or hot water supply, heating system, wall heating and radiating system, central air condition system, industrial liquid transportation Advantages: 1. High temperature resistance: the maxium sustained working temperature is up to 70 degree celsius, the maximum transient temperature is up to 95 degree celsius. 2. Heat preservation: low thermal conductivity which is only 1/1500 of brass pipe, and 1/250 of steel pipe. 3. Non-toxic: no heavy metal additives, would not be covered with dirt or contaminated by bacterium. 4. Lower installation costs: light weight and ease of installation can reduce installation costs by as much as 50% over metal piping system 5. Higher flow capacity: smooth interior walls result in lower pressure loss and higher volume than metal pipes. 6. Long life: more than 50 years under normal conditions. 7. Recycled and environment-friendly
