PE Water Pressure Pipe 20 mm (1/2 inch)
Products in this size: PE100 Water Pressure Pipe and PE80 Water Pressure Pipe. Its pressure classes run from PN12.5 to PN25 (SDR 11 to 7.4): the lower the SDR, the thicker the wall and the higher the allowed pressure. Wall thickness 2–2.8 mm, inside diameter 14.4–16 mm and weight 0.118–0.164 kg per metre.
Supplied as: Coil (50, 100, 200 m). In the Iranian market a 20 mm pipe is also called “1/2 inch”. That is a trade name: the real size of a PE pipe is its outside diameter, 20 mm.
