原始设备制造商的出口质量标准pp-r管

OEM export quality standardpp-r pipe Features: 1. Material: Random Polypropylene; 2. Size: 20mm to 160mm; 3. Pressure Rating: 1.25Mpa, 1.6Mpa, 2.0Mpa, 2.5Mpa; 4. Colors: White, green, grey or other colors on request; 5. Standard: DIN8077, DIN8078; 6. Certification: ISO9001:2000; 7. Applications:Cold or hot water supply, heating system including flooring heating, wall heating and radiating system, central air conditioning system, industrial liquids transportation.Advantages: 1. High Temperature Resistance: The maximum sustained working temperature is up to 70 Degrees Celsius, the the maximum transient temperature is up to 95 Degrees 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. Corrosion Resistant: Resist chemical matters or electron chemical corrosion; 5. Lower Installation Costs: Light weight and easy of installation can reduce installation costs by as much as 50% over metal piping system; 6. Higher Flow Capacity: Smooth interior walls result in lower pressure loss and higher volume than metal pipes; 7. Long Life: More than 50 years under normal conditions; 8. Recycled and Environment-friendly.
