What does SDR6 / PN20 mean for PP-R pipes?
SDR (Standard Dimension Ratio) is the ratio of the pipe's outer diameter to its wall thickness. SDR6 indicates a thicker wall, yielding a PN20 pressure rating — meaning the pipe can withstand a continuous operating pressure of 20 bar at 20°C. This makes SDR6/PN20 pipes ideal for high-pressure hot and cold water systems in commercial and residential buildings across Dubai and the GCC.
