GF+ Aquasystem PP-R UV-Resistant Pipe SDR6 (PN20)
GF+ Aquasystem PP-R UV-Resistant Pipe SDR6 (PN20) — A PP-R pipe with a black protective coating whose outer layer is resistant to sunlight (UV). Standard PP-R pipe becomes brittle over time in sunlight; the UV-resistant pipe was developed for outdoor installations.
Applications
- Roof and terrace installations, solar energy systems
- Garden, irrigation and open-area lines
- Facades and open shafts
Key features
- UV-resistant outer layer
- Inner layer standard Aquasystem PP-R: welded with the same fittings
- SDR6, PN20 pressure rating

Socket fusion welding times
| Pipe diameter | Welding depth (mm) | Heating (s) | Joining time (s) | Cooling (min) |
|---|---|---|---|---|
| Ø20 | 14 | 5 | 4 | 2 |
| Ø25 | 15 | 7 | 4 | 2 |
| Ø32 | 16.5 | 8 | 6 | 4 |
| Ø50 | 20 | 18 | 6 | 4 |
| Ø63 | 24 | 24 | 8 | 6 |
Values per DVS 2207-11 at +20 °C ambient and 260 °C heating tool temperature. Below +5 °C, extend the heating time by about 50%. Heating time starts when pipe and fitting are fully seated on the heating dies; during the joining time the parts may be aligned axially without twisting.
Installation tips
- Cut the pipe square with a pipe cutter and mark the welding depth on the pipe.
- Push pipe and fitting onto the heating dies at the same time without twisting; when the heating time is over, join them quickly and axially.
- Do not twist the parts after the joining time; do not pressurize the line before the cooling time has passed.
- Pressure-test the installation before closing walls or screed.
Frequently asked questions
Is there any difference in welding?
