Fig. 4: Press connectors
The Megapress press connectors consist of non-alloy steel (mate-
rial 1.0308) and have an external high-quality 3–5 µm zinc-nickel
coating. There is a cutting ring, a separator ring and a profile sealing
element in the bead of the press connector. The cutting ring cuts into
the pipe during pressing and ensures a force-fit connection.
During installation, and later during the pressing, the separator ring pro-
tects the sealing element from damage from the cutting ring.
Fig. 5: SC-Contur
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 connector is guaranteed to be leaky in an unpressed state. In
this way, inadvertently unpressed connections are noticed immediately
during a leakage test.
Viega guarantees that unpressed connections are visible during a
leakage test:
n
with the wet leakage test in the pressure range from 0.1–0,65 MPa
(1.0–6.5 bar)
n
with dry leakage test in the pressure range from 22 hPa–0.3 MPa
(22 mbar–3.0 bar)
