About 50MM HDPE WATER PIPE SDR-21

50MM HDPE PIPE SDR-21 DESCRIPTION

The 50MM HDPE Pipe SDR-21 is a reliable and cost-effective piping solution manufactured from high-grade High-Density Polyethylene (HDPE). With a Standard Dimension Ratio (SDR) of 21, this pipe is designed for low to medium pressure applications, offering an ideal balance of durability, flexibility, and performance.

This pipe is widely used in water distribution, agricultural irrigation, and cable ducting systems. Its excellent resistance to corrosion, chemicals, and environmental stress ensures long-lasting performance even in harsh conditions.

The inner surface of the pipe is smooth, allowing efficient flow with minimal friction loss. Additionally, the pipe is UV stabilized, making it suitable for both underground and above-ground installations.
