HDPE MUNICIPAL PLUMBING SYSTEM

The RIFENG HDPE water supply pipe is a new type of plastic pipe using high-quality polyethylene, also adding necessary antioxidants, ultraviolet absorbers, and other additives, then processed by an extruder. The product has the advantages of being lightweight, flexible, corrosion resistant, and highly impact resistant.

The connection of the pipe and fittings can be integrated with butt welding, hot-melt socket, and electrofusion. This system is safe, reliable, and low-cost, and has been widely used in engineering.
