SDR-21 200MM HIGH DENSITY POLYETHYLENE PIPES

SDR 21 200 MM HDPE Pipe Description, Key Features, and Uses

Product Description

The SDR 21 200 MM HDPE Pipe is a high-quality pipe made from High Density Polyethylene (HDPE), designed for reliable performance in medium-pressure pipeline systems. The Standard Dimension Ratio (SDR) of 21 represents the ratio of the pipes outer diameter to its wall thickness, ensuring an optimal balance between strength, durability, and flexibility.

With a 200 mm outer diameter, this HDPE pipe provides efficient flow capacity for water distribution and industrial fluid transport. The pipe features a smooth inner surface, which minimizes friction and allows better flow efficiency. HDPE pipes are highly resistant to corrosion, chemicals, and environmental stress, making them suitable for long-term use in demanding conditions.

The pipe is lightweight compared to traditional materials like steel or concrete, making transportation, handling, and installation easier. It can be joined using butt fusion or electrofusion techniques, creating strong and leak-proof joints. Due to its durability and low maintenance requirements, the SDR 21 200 MM HDPE pipe is widely used in modern infrastructure and utility projects.
