Sanpress Inox

General

Press connector system with press connectors and pipes made of stainless steel material Nos. 1.4401 and 1.4521 in acc. with DIN EN 10088, DIN EN 10312, DVGW worksheet GW 541, system certification for connectors and pipes in acc. with DVGW worksheet W 534, for drinking water installations in acc. with DIN 1988. For dimensionally stable concealed and pre-​wall installations of manifold and riser pipes in Viega component assembly.

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 W 534, Point 12.14, Connectors with forced leakage.
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 compressed air or noble gases from 22 hPa–0.3 MPa.

    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: www.viega.co.uk
