Details of PEX Floor Heating Pipe
we transform the ordinary polyethylene molecular structure into a three-dimensional network crosslinking system to achieve:
Temperature tolerance: -70℃~110℃ working range
(instant temperature resistance up to 130℃)
Pressure performance: PN10 rated pressure 95℃ hot water long-term operation
Memory effect: Unique shape recovery features to avoid permanent creases
Corrosion resistance: Resistance to acid-base media (pH2-12) and microbial attack

Q: How to choose PEX pipe and aluminum-plastic pipe?
A: In the field of radiant heating, all-plastic PEX tubes have better heat transfer efficiency (thermal conductivity 0.38 vs 0.45 W/mK) and lower linear expansion rate (0.035% vs 0.025%/℃).
