Transition to the Pexfit Pro piping system
The Viega Speedpress piping system is compatible with the Pexfit Pro piping system, and they can be connected directly to each other using the adapters intended for this purpose.
Further information on Pexfit Pro can be found in the online instructions for use .

d16, 20, 25 |
Laying and fixing pipes
Only pipe clamps with chloride-free sound insulating inlays should be used to secure the pipes.
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:
d x s [mm] | Horizontal Multi-layer pipe [m] | Vertical Multi-layer pipe [m] | Horizontal Solid plastic pipe [m] | Vertical Solid plastic pipe [m] |
|---|---|---|---|---|
16 x 2.0 | 1.00 | 1.30 | 0.55 | 0.75 |
20 x 2.3 | 1.00 | 1.30 | 0.55 | 0.80 |
25 x 2.8 | 1.50 | 1.95 | 0.65 | 0.90 |
Length expansion
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)
Heat expansion co-efficients of various pipe materials
Material | Heat expansion co-efficient ⍺ | Example: |
|---|---|---|
PE-RT Type II/Al/PE-RT Type II | 0.03 | 30 |
PE-RT Type II | 0.2 | 200 |
Calculation example multi-layer pipe
Given: Temperature difference Δ ϑ = 50 K; pipe length L = 8 m; pipe Ø = 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.
- 1 - Length expansion ∆l [mm]
- 2 - Temperature difference ∆ϑ [K]
- 3 - Pipe length L [m]
- 4 - Expansion bend length LBS [mm]
Press connectors
The press connectors of the Viega Speedpress system consist of the following materials:
Brass
PPSU
Transition press connector
The Viega Speedpress piping system is compatible with the Pexfit Pro piping system, and they can be connected directly to each other using the adapters intended for this purpose.
Further information on Pexfit Pro can be found in the online instructions for use .
SC‑Contur
Viega press connectors are equipped with the SC‑Contur. SC‑Contur is a safety mechanism certified by the DVGW and ensures that the press connector leaks 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)
Markings on components
Pipe marking
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
Markings on press connectors
The press connectors are marked with a coloured dot. The dot identifies the SC‑Contur where the test medium would escape in the case of an inadvertently unpressed connection.
The green dot shows that the press connector is equipped with the SC‑Contur and that the system is suitable for potable water.
Viega Speedpress press connectors may be connected with pipes from the Viega Speedpress system.
Information for use
Chemical resistance
NOTICE!
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.
NOTICE!
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.
NOTICE!
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 system components to permanent UV radiation.
Handling
Storage
For storage, comply with the requirements specified in the applicable regulations, see Regulations from section: Storage :
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.
Assembly information
Mounting instructions
NOTICE!
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.
Viega Service Center: customercare@viega.in
NOTICE!
Product damage due to permanent tension!
Risk of damage to the system if press connectors are installed under permanent tension.
Install press connectors free of tension.
NOTICE!
Product damage due to improperly positioned press sleeves!
Improperly positioned press sleeves cause faulty pressing.
Ensure that the press sleeve sits straight on the press connector.
INFO!
Insert a pipe into a distorted press sleeve to restore the round shape of the press sleeve to make it fit for mounting.
Checking system components
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.
Only use pipes whose surfaces are free of grooves or scratch marks.
NOTICE!
Check that the sealing element of the brass connectors is properly positioned.
