PP-R fitting/PP-R threaded coupling

1. Colours: Light grey, Blue, Yellow or other colours on request 2. Connection: Welding 3. Standard: GB/T18742.3 4. Application: Cold or hot water supply, heating system, wall heating and radiating system. 5. High Temperature Resistence: the maximum sustained working temperature is up to 95°C, the maximum transient temperature is up to 120°C. 6. Heat preservation: low thermal conductivity which is only 1/1500 of brass pipe. And 1/250 of steel pipe.7. Non-toxic: no heavy metal additives, would not be covered with dirt or contaminated by bacterium.8. Corrosion Resistant: resist chemical matters or electron chemical corrosion.9. Lower Installation Costs: light weight and ease of installation costs by as much as 50% over metal piping system.10. Higher Flow Capacity: smooth interior walls result in lower pressure loss and highervolume than metal pipes.11. Long Life: more than 50 years under normal conditions.
