Product Description:
Donghong Large-Diameter PE Pipes are designed for high-capacity water transmission and demanding infrastructure applications. Available in sizes up to DN2000, they are particularly suitable for large-diameter pipelines requiring high flow capacity, corrosion resistance and reliable long-term performance.
For desalination projects, the pipes can be used for seawater intake, seawater transmission, treated water conveyance and discharge systems, providing a lightweight and corrosion-resistant alternative to traditional metal pipelines.
