Only pipe clamps with chloride-free sound insulating inlays should be used to secure the pipes.
For fastening the pipes on Prevista Dry Plus rail systems, Viega recommends the use of the Prevista Dry Plus piping support (model 8416). The piping support is suitable for plastic pipelines with dimensions d16 to 20.
Observe the general rules of fixing technology:
Do not use fixed pipelines as a support for other pipelines and components.
Do not use pipe hooks.
Observe distance to press connectors.
Observe the expansion direction: Plan fixed and gliding points.
Make sure to affix the pipelines in such a way as to de-couple them from the installation body, so that they cannot transfer any structure-borne sound, resulting from thermal expansion or possible pressure surges, onto the installation body or other components.
Observe the following fixing distances:

Pipelines expand with heat. Heat expansion is dependent on the material. Changes in length lead to tension within the installation. These tensions must be compensated for with suitable measures.
The following are effective:
Fixed and gliding points
Expansion equalisation joints (expansion bends)
Material | Heat expansion co-efficient ⍺ | Example: Length expansion with pipe lengths L = 20 m and ΔT = 50 K |
---|---|---|
Raxofix multi-layer pipe (dimensionally stable with oxygen barrier layer) | 0.03 | 30 |
Calculation example Raxofix multi-layer pipe (dimensionally stable with oxygen barrier layer):
Given: Temperature difference Δ ϑ = 50 K; Pipe length L = 8 m; Pipe ⌀ = 20 mm
Required: Expansion bend lengthLBS
Calculation:
Beginning in the left-hand diagram: From 50 K temperature difference on the x-axis up to the characteristic line for the 8 m pipe length.
Connect the intersection horizontally with the right-hand diagram up to the intersection of the characteristic line for pipe diameter 20 mm.
Result: Read the value from the x-axis:LBS = 480 mm.
Viega press connectors are equipped with the SC‑Contur. The SC‑Contur is a safety technology that is certified by the DVGW and ensures that the press connector is guaranteed to be leaky in an unpressed state. In this way, inadvertently unpressed connections are noticed during a leakage test.
Viega guarantees that accidentally unpressed connections become visible during a leakage test:
with the wet leakage test in the pressure range from 0.1–0.65 MPa (1.0–6.5 bar)
with dry leakage test in the pressure range from 22 hPa–0.3 MPa (22 mbar–3.0 bar)
The pipe markings contain important information regarding the quality and certification of the pipes. Their meaning is as follows:
Manufacturer
System name
Pipe material
Size / wall thickness
Certification and operating temperatures
The green dot shows that the press connector is equipped with the SC‑Contur and that the system is suitable for potable water.
All Raxofix pipes may be mounted only using original accessories, Raxofix press connectors using SC‑Contur and the corresponding press tools. Use with components of other plastic piping systems, such as Sanfix Fosta, for example, is not permitted.
Please contact Viega for questions on this subject.
Damage to material due to aggressive chemicals
Aggressive chemicals, especially those containing solvents, may cause material damage and leaks. This may lead to water damage.
Prevent contact between the system components and aggressive chemicals.
Material damage due to impermissible leakage detection agents
Impermissible leakage detection agents may cause material damage and leaks. This may lead to water damage.
Use only leakage detection agents approved by the manufacturer for use on PPSU material.
Observe the manufacturer's notes on processing.
Material damage due to UV radiation
Permanent UV radiation can lead to material damage and leaks. This may lead to water damage.
Do not expose the pipes to permanent UV radiation.
For storage, comply with the requirements specified in the applicable regulations, see Regulations from section: Storage :
Store rods on even, clean surfaces.
Storage outside in closed, original packaging is possible for a period of up to three months. In this instance, protect the packaging from damage due to rain or high levels of humidity or UV radiation.
Material damage due to thread locker containing solvents!
Thread lockers containing solvents can lead to material damage and leaks in plastic parts of pipe connections. This may lead to water damage.
As a sealant, only use commercially available hemp together with thread sealing paste or certified sealing tape for potable water.
Please contact the Viega Service Center if you have any questions.
System components may, in some cases, have become damaged through transportation and storage.
Check all parts.
Replace damaged components.
Do not repair damaged components.
Contaminated components may not be installed.
