Sanpress Inox G

Press connector system with press connectors and pipes made of stainless steel material No. 1.4401 in acc. with EN 10088, DVGW worksheet GW 541, gases in acc. with DVGW worksheet G 260 in gas installations in acc. with DGVW-​TRGI 2008 (DVGW worksheet G 600) / DVFG-​TRF 2012.
  • Liquid gas in the gas phase for domestic and commercial applications, tested in acc. with DVGW worksheet G 5614
  • Heating oil pipelines for heating oil in acc. with DIN 51603‑1 and diesel fuel pipelines for diesel fuel as suction and pressure pipeline in acc. with EN 590 under consideration of the building control Z-38.4‑184 (d 15–54 only)

For dimensionally stable pre-​wall and concealed installations of manifolds and riser pipes as well as suction and pressure pipes in heating oil installations.

Press connectors
All sizes with SC‑Contur - connections, which remain unpressed become visible when the system is filled. The SC‑Contur is certified and fulfils the requirements of DVGW worksheet G 5614. Point 4.4.1, Connectors with forced leakage.
During leakage tests with water, Viega guarantees the identification of unpressed connections in the pressure range 1.0 bar -6.5 bar, in the case of a dry leakage test with compressed air or noble gases from 22 mbar -3.0 bar.

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.

Technical data
Press connectors and components are constantly being optimised. If required, the current Z and installation dimensions can be obtained from the download area of the Viega website:
