Introduction of High Quality Crosslinking Пolyethylene Пајпе
PEX (Cross-linked Polyethylene) 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 Пolyethylene Пајпе
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
Intergenerational evolution of product technology
| Features | First generation PE-RT | Second generation PEX-B | Third generation PEX-A |
| Degree of crosslinking | no | 65-70% | ≥75% |
| Temperature rating | Class III | Level IV | Level V |
| Coefficient of thermal expansion | 0.18 mm/m ℃ | 0.15 mm/m ℃ | 0.12 mm/m ℃ |
| Burst pressure (95 ° C) | 5.2 MPa | 6.8 MPa | 8.4 MPa |
* Note: Data in this table are based on ISO15875 international standard test environment *
Specifications of High Quality Crosslinking Пolyethylene Пајпе
Standard pipe parameter matrix
| Specification and model | Outside diameter (мм) | Wall thickness (мм) | 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)
Топлинска спроводливост: 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

Најчесто поставувани прашања на High Quality Crosslinking Polyethylene Pipe
Q: How to choose PEX pipe and aluminum-plastic pipe?
А: 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?
А: 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
