HDPE white coated pipes are manufactured using co-extrusion technology, where:
- Inner layer: standard HDPE (usually black)
- Outer layer: reflective white coating integrated with the pipe during manufacturing.
This white layer is designed to reflect sunlight and reduce heat absorption.
Key Features
- High UV resistance – protects the pipe from sunlight.
- Lower heat absorption – white color reflects solar radiation.
- Corrosion resistance – typical HDPE property.
- Lightweight and flexible – easy to install.
- Long service life – resistant to chemicals and weather.
Why White Coating Is Used
Compared with normal black HDPE pipes:
- White coating reduces temperature rise in pipes exposed to sun.
- Helps protect the transported fluid from overheating.
- Improves visibility and safety in outdoor installations.
Common Applications
- Above-ground water pipelines
- Mining slurry pipelines
- Industrial fluid transport
- Temporary water supply systems
- Hot climates / desert environments
