PE-RT floor heating pipe (orange, other color please contact us) raised temperature resistant. Polyethylene (PE -RT) pipe can choose different materials as customers鈥?requirement. They are separately Korea chemical SK 800 and Korea LG chemical SP980. The position on main link and density of short branch make PE-RT pipe with excellent hydraulic pressure resistant and compact resistant performance. No need cross linking process. The Product 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.
