What this pipe is used for
Every application below is one the PP-R Composite Pipe is specified for, with the manufacturer's note that supports it.
Hot and cold water
Suitable for hot and cold water transfers in buildings and under-floor and central heating systems, rated to 25 bar.
Drinking-water supply
They have a high resistance for high temperature, pressure and they are suitable for drinking water.
High-pressure water supply
PN12.5/25 — 25 bar at 10°C–30°C.
Farms and irrigation
Suitable for other use in industry and agriculture, with a 25 bar rating.
Why this pipe

- Higher bore size and operating pressure than normal PN20 PP-R
- Smooth, non-porous bore means low pressure drop and reduced noise
- Composition
- 3 layers: PP-R & inner layer
- Pressure rating
- 25 bar (PN12.5/25)
- Length
- 4 metres
- Colour
- White outer and inner layers; maroon inner
Advantages
No water-hammer & pressure drop
The internal surface of the pipes are smooth, homogeneous, and non-porous. Due to low flow resistance, the pressure drop is less. It has higher flow rates and a wider range of applications with exceptional impact resistance and reduced noise generation.
Long service-life under aggressive working conditions
The quality of the raw material and the high manufacturing technology used to produce them ensure long-life reliable products.
Better flow rate
Compared to normal PN20 PP-R pipes, it has a higher bore size and higher operating pressure at the same operating temperature.
Hygienic, non-toxic & environmentally friendly
All materials used in the production are non-toxic in accordance with current international standards and are completely safe for use with liquid consumables.
