About SDR 21 140MM HIGH DENSITY PLOYETHYLENE PIPES

Description of SDR 21 140 mm HDPE Pipe

The 140 mm HDPE Pipe (SDR 21) is a durable and high-performance piping solution manufactured from High Density Polyethylene (HDPE) material. It is designed for efficient water transportation and distribution in various applications such as municipal water supply, irrigation systems, and industrial pipelines. The SDR 21 classification represents the ratio between the pipes outer diameter and wall thickness, making it suitable for medium-pressure water supply systems.

This pipe is produced using high-quality polyethylene material and modern extrusion technology, ensuring excellent strength, flexibility, and long service life. The smooth inner surface helps maintain efficient fluid flow with minimal friction loss, improving overall pipeline performance.

The 140 mm SDR 21 HDPE pipe is lightweight compared to traditional piping materials, making it easy to transport and install. It can be joined using butt fusion or electrofusion welding, which creates strong and leak-proof connections. The pipe is also resistant to corrosion, chemicals, and environmental stress, making it suitable for both underground and outdoor installations.
