One-layer pressure polypropylene pipe S2,5 (SDR6) PN 16 is purposed for cold and hot water supply systems with water temperature up to +60 °C, nominal pressure of 16 bars. Distinctive feature of this pipe is an enforced side and extended service period. It has a bigger carrying capacity compared with SDR6 pipes. When using this pipe for hot water supply, the application of compensating pipes is necessary. In one layer pipes, multiple freezing/unfreezing of heat carrying agent is allowed.
