  1.Material: Random Polypropylene
2.Size: full 16mm through 160mm availability
3.Pressure Rating: 1.25MPa, 1.6MPa, 2.0MPa,2.5MPa
4.Colors:Light grey or white, pipe for cold water is marked with blue stripes, pipe for hot water is marked with red stripes.Other colors are also available upon request.
5.Form Supplied:4 meters straight length (all size) .
Other forms are also available upon request.
6. Standard: GB/T 18742.2-2002
Advantages
1.High Temperature Resistance:the maximum sustained working temperature is up to 70 , the maximum transient temperature is up to 95.
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 Resistance: resist chemical matters and electron chemical corrosion
5.High Flow Capacity: smooth interior walls and low friction result in low flow resistance
and high volume.
6.Excellent Flexibility: can be supplied in coil.
7.Low Installation Costs: light weight and ease of installation can reduce installation costs.
8.Longevity:more than 50 years under proper use.
9.Recycled and Environment-friendly
