PE Water Pressure Pipe 125 mm (5 inch)
Products in this size: PE100 Water Pressure Pipe and PE80 Water Pressure Pipe. Its pressure classes run from PN4 to PN25 (SDR 41 to 7.4): the lower the SDR, the thicker the wall and the higher the allowed pressure. Wall thickness 3.1–16.9 mm, inside diameter 91.2–118.8 mm and weight 1.23–5.77 kg per metre.
Supplied as: Bar (6, 12 m). In the Iranian market a 125 mm pipe is also called “5 inch”. That is a trade name: the real size of a PE pipe is its outside diameter, 125 mm.
