125MM HDPE WATER PIPE SDR-21 About

125MM HDPE PIPE SDR-21 DESCRIPTION

The 125MM HDPE Pipe SDR-21 is a durable, lightweight, and cost-effective piping solution manufactured from high-quality High-Density Polyethylene (HDPE). Designed with a Standard Dimension Ratio (SDR) of 21, this pipe is suitable for low to medium pressure applications, offering an excellent combination of flexibility, strength, and long service life.

This pipe is widely used in water supply systems, agricultural irrigation, and underground cable ducting due to its outstanding resistance to corrosion, chemicals, and environmental stress cracking. Its smooth inner surface ensures efficient flow with minimal friction loss, improving overall system performance.

The pipe is UV stabilized, making it suitable for both underground and above-ground installations in diverse environmental conditions.
