Viega Smartpress


Viega Smartpress

Flow-​optimised press connector system with multilayer pipes for drinking water and heating. Tested in acc. with DVGW worksheet534.

Press connectors
Safe and fast processing without calibration of the pipe ends through O-​ring-​free press technology in all dimensions. Aerodynamic radii and minimal cross-​section narrowings ensure minimal pressure losses. This allows a smaller dimensioning of drinking water installations and reduces the pipeline volume.
All sizes with SC‑Contur - connections, which remain inadvertently unpressed become immediately visible during the leakage test.
During leakage tests with water, Viega guarantees the identification of unpressed connections in the pressure range 0.1 MPa–0.65 MPa, in the case of a dry leakage test with gases from 22 hPa–0.3 MPa.

Elbows, T-​pieces and couplings made of stainless steel
Press connectors with threaded connection and reductions made of silicon bronze
d 16–25
Elbows, T-​pieces, couplings and manifolds made of PPSU only for drinking water and heating installations

Areas of application
Drinking water

Use of the system for application areas and media other than those described here must be agreed with Viega Service Center.

Operating conditions
Drinking water installations
  • Operating temperature max. 70 °C
  • Operating pressure max. 1.0 MPa
Heating installations
  • Operating temperature max. 8°C
  • Operating pressure max. 1.0 MPa
Irrelevant of the direction of flow, mixed installations are permitted.

The system components should be protected against high concentrations of chloride generated by both the medium and by external factors. Use only of original Viega parts - installation of non-​Viega parts is not permitted.

Use of press tools
The functional safety of the Viega press connector systems is primarily dependent on the perfect condition of the press tools and press machines used. For this reason, for the production of press connections, we recommend the use of Viega press tools and their regular inspection by authorised service points.
