1/2inch. Pex Plumbing Pipes for Water Supply Systems in Radiant Heating
China 1/2inch. Pex Plumbing Pipes for Water Supply Systems in Radiant Heating, Find details about China Pex Pipe, Pex-B Pipe from 1/2inch. Pex Plumbing Pipes for Water Supply Systems in Radiant Heating
PEX pipe is produced with crosslinked polyethylene. Crosslinking is obtained through a chemical process that increases the bonds between macromolecules to form a more complex structure than the normal polyethylene. Due to the crosslinking, the polyethylene's performance is greatly enhanced still maintaining the excellent properties of thermoplastics.
HEWAI PEX pipe is a ideal solution for underfloor heating system, it provides a superior, efficient & clean heating system by distributing heated water from a heart source through a piping network. The PEX heating pipe has excellent mechanical performances and the ability to withstand instand high temperature up to 110ºC. At the same time, HEWAI PEX pipes can be manufactured into coils up to 500 meters,with efficient & no-fuss installation.

1.100% new material
2.Max. temperature can reach 95degrees
3.Welding way:overlap & laser
Advantages of Our Pipes:
1.High Temperature Resistance: The maximum sustained working temperature is up to 70 Degrees Celsius, 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 ease 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.
