Understanding PN & SDR Ratings

PN (Pressure Nominal) indicates the maximum working pressure in bars. SDR (Standard Dimension Ratio) defines the pipe wall thickness relative to its outer diameter — a lower SDR means thicker walls and higher pressure capacity. For deep underground or high-pressure municipal lines in Karachi, we recommend PN-16 / SDR-11.
