Conductă de încălzire prin pardoseală PEX rezistentă la temperaturi ridicate

Introducere a PEX Floor Heating Pipe

Conductă de încălzire prin pardoseală PEX rezistentă la temperaturi ridicate is one of the most important material innovations in the field of HVAC in the 21st century. Through the high energy electron irradiation crosslinking process (PEX-A) or silane hydrolytic crosslinking technology (PEX-B).

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
• Rezistenta la coroziune: Resistance to acid-base media (pH2-12) and microbial attack

FAQ of PEX Floor Heating Pipe

Î1: How to choose PEX pipe and aluminum-plastic pipe?

O: 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%/℃).

Q2: Floor heating pipe spacing design specification?

O: According to EN1264 standard:

Conventional area: 200mm spacing (pipe diameter 16mm)

Edge area: 150mm encryption area (extending 1.5m to external wall)

Baie: 175mm spacing + border insulation tape
