Introduction of Floor Heating Pipes

Details of Floor Heating Pipes

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

耐食性: Resistance to acid-base media (pH2-12) and microbial attack

Specifications of Floor Heating Pipes

Standard pipe parameter matrix

Specification and model	Outside diameter (mm)	Wall thickness (mm)	SDR value	Pressure rating	Length of applicable loop
PEX – 16 x 2.0	16	2.0	8.0	S4	≤80m
PEX – 20 x 2.3	20	2.3	8.7	S3.2	≤100m
PEX-25×2.8(enhanced)	25	2.8	8.9	S2.5	≤120m

SDR (Standard dimension ratio) : The ratio of outer diameter to wall thickness determines the balance of rigidity and flexibility of the pipe

Oxygen permeability: EVOH oxygen blocking layer ≤0.1g/m³·day (DIN4726 standard)

Thermal conductivity: 0.38W/(m·K) (30% better than copper pipe)

Analysis of multi-layer composite structure

Five-layer co-extrusion process:

1. Inner layer: PEX-A antibacterial layer (silver ion coating)

2. Bonding layer: modified polyethylene

3. Oxygen blocking layer: EVOH (ethylene-vinyl alcohol copolymer)

4. Reinforcing layer: glass fiber reinforced PEX

5. Outer layer: anti-UV modified layer

FAQ of Floor Heating Pipes

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
