About 200MM HDPE WATER PIPE SDR-21

200MM HDPE PIPE SDR-21 DESCRIPTION

The 200MM HDPE Pipe SDR-21 is a high-strength, durable, and economical piping solution manufactured from premium quality High-Density Polyethylene (HDPE). Designed with a Standard Dimension Ratio (SDR) of 21, this pipe is ideal for low to medium pressure applications, offering an excellent balance between flexibility, toughness, and long service life.

This pipe is widely used in large-scale water supply systems, irrigation projects, and underground cable ducting. Its superior resistance to corrosion, chemicals, and environmental stress cracking ensures reliable performance even in demanding conditions.

The pipe features a smooth inner surface, which reduces friction loss and ensures efficient fluid flow. Additionally, it is UV stabilized, making it suitable for both underground and above-ground installations.
