SDR 9 pipe is a high-strength plastic pipe, often made of HDPE, with thick walls relative to its diameter, making it suitable for high-pressure applications such as urban water supply, industrial processes, and fire fighting systems. The "SDR 9" designation refers to its Standard Dimension Ratio, where the nominal outside diameter is 9 times the wall thickness, indicating a higher pressure rating compared to pipes with higher SDR values. Its purpose is to provide a durable, corrosion-resistant, and flexible conduit for fluid transportation, ensuring system integrity with reliable hot-melt connections and longevity of 50+ years.
