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
