FAQ of High Quality Crosslinking Polyethylene Pipe
សំណួរ: How to choose PEX pipe and aluminum-plastic pipe?
ក: 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%/℃).
សំណួរ: Floor heating pipe spacing design specification?
ក: 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
