That material honesty is what turns a PPR hot water plumbing pipe into a 50-year asset under continuous 70°C service. Our virgin PPR hot water pipe carries an SDR 7.4 wall on diameters from 20 mm to 110 mm, delivering a PN20 rating with full safety margin, and the internal bore stays glass-smooth after thousands of thermal cycles.
