- Applications: Cold or hot water supply, heating system including flooring heating, wall heating and radiating system, Central air conditioning system, industrial liquids transportation
Advantages:
- High Temperature Resistance: the maximum sustained working temperature is up to 70 Degrees Celsius, the maximum transient temperature is up to 95 Degrees Celsius
- Heat Preservation: low thermal conductivity which is only 1/1500 of brass pipe, and 1/250 of steel pipe
- Non-toxic: no heavy metal additives, would not be covered with dirt or contaminated by bacterium
- Corrosion Resistant: resist chemical matters or electron chemical corrosion
- Lower Installation Costs: light weight and ease of installation can reduce installation costs by as much as 50% over metal piping system
- Higher Flow Capacity: smooth interior walls result in lower pressure loss and higher volume than metal pipes
- Long Life: more than 50 years under normal conditions
- Recycled and Environment-friendly
