Introduction of High Quality Crosslinking Polyethylene Pipe

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 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

जंग प्रतिरोध: Resistance to acid-base media (pH2-12) and microbial attack

Specifications of High Quality Crosslinking Polyethylene Pipe 

Standard pipe parameter matrix

Specification and modelबाहिरी व्यास (mm)Wall thickness (mm)SDR मूल्यदबाव मूल्याङ्कनLength of applicable loop
PEX – 16 x 2.0162.08.0S4≤80m
PEX – 20 x 2.3202.38.7S3.2≤100m
PEX-25×2.8(enhanced)252.88.9S2.5≤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)

थर्मल चालकता: 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 को उच्च गुणस्तरको क्रसलिङ्किङ पोलिथीन पाइप

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

ए: In the field of radiant heating, all-plastic PEX tubes have better heat transfer efficiency (thermal conductivity 0.38 बनाम 0.45 W/mK) and lower linear expansion rate (0.035% vs 0.025%/℃).

प्र: Floor heating pipe spacing design specification?

ए: 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
