UV-Resistant White HDPE Pipe

Donghong UV-Resistant Black & White PE Pipes are specially developed for long-term outdoor pipeline applications exposed to strong solar radiation and high ambient temperatures.

The white outer layer reflects a significant portion of solar radiation, helping reduce pipe surface temperature and heat transfer to the conveyed fluid. The black inner layer provides additional UV protection, while the integrated co-extruded structure enhances long-term stability.

The pipe is particularly suitable for outdoor water transmission, agricultural irrigation, mining and other infrastructure projects in hot and high-UV environments.

Product Highlights

• Enhanced UV Resistance — Special UV-resistant materials help protect the pipe during long-term outdoor exposure.

• Lower Surface Temperature — The white outer layer reflects solar radiation and reduces heat absorption.

• Lower Fluid Temperature Rise — Reduced heat transfer helps limit temperature increase of the conveyed fluid.

• Black Inner Layer — Provides additional protection against UV penetration and supports long-term durability.

• Integrated Co-Extrusion — Black and white PE layers are manufactured as an integrated structure using compatible PE materials.

• Long-Term Outdoor Performance — Designed for demanding outdoor applications in hot and high-UV environments.

• Cost-Effective — Helps reduce maintenance and replacement requirements over the pipeline service life.
