Product Description

A double-layer PPR pipe consists of two distinct inner and outer layers, integrating advantages such as antibacterial performance on the inner surface and light-shielding capability to inhibit algae growth. Its outer layer is designed to resist UV radiation or enable color identification, making it highly suitable for cold water applications and outdoor installations. Renowned for their sanitation, long-lasting performance, and smooth fluid conveyance, these pipes are widely used in residential, commercial, and industrial plumbing projects, with connections achieved through heat fusion technology.
