Introduction of High Quality Crosslinking Polyethylene Pipe
e (Polyethylene txuas hla) cross-linked polyethylene pipe 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 High Quality Crosslinking Polyethylene 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

FAQ of Yeeb nkab Polyethylene Zoo Siab
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%/℃).
Q: Floor heating pipe spacing design specification?
A: According to EN1264 standard:
Conventional area: 200mm spacing (pipe diameter 16mm)
Edge area: 150mm encryption area (extending 1.5m to external wall)
Bathroom: 175mm spacing + border insulation tape
