INTRODUCTION
PP-R pipe is a new generation of environment-friendly construction material developed in 1990s. Besides plastic pipe merits, such aslightness, corrosion resistance, anti-deposition and ong service life, Pp-R pipe also have some new advantages,like hvgienism, heatresistant, material recycled. in the meanwhile, lower coefficient of heat conductivity can help for energy conservation. The usage oithermosol binding technique can make the process of installation very convenient.Qualified raw material, from Korea, was used for YFENG PP-R piping networks. The performance standard of PP-R products canmatch DIN8077 & DIN8078 ,IS0 15874,and GB/T18742.
Long Service Life:
A PN20 water pipe, transporting water at 30’c can last for more than 50 years, under normal conditions with an operating pressure of 21.8 bars.
Hygienism and Non-toxic:
The material is a new type environmental building material, which can be used in pure water piping system.
Heat-resistant:
Under 9.7 bars pressure and 95’C hot water, the PN25 hot water pipe can continue to work one year.
Corrosion-resistant:
For most of the ions in the water and chemical substances in the building, there is not chemical reaction, no rust and no corrosion with PP-R piping system.
Thermal Insulation and Energy Conservation:
The thermal conductivity coefficient is only 1/200 of the metal pipe.
Light Weight and High Intensity:
The proportion is only 1/8 of the metal pipe.The pressure resistance test intensity reaches 5MPa (50kg/cm) or above.
Attractive Appearance:
Smooth internal and external wall, low flow-resistant, mild color and exquisite appearance.
Easy and Reliable Installation:
it adopts thermosol binding coniunction, no threaded, and it will only take several seconds for connection. High-quality coppel inlay pieces are adopted, when it connects with metal pipe or water consumption machines, it is safe and reliable.
