3. SMART CONNECT FEATURE
3.1 Viega Smart Connect
Feature
In ProPress 1/2" to 4" dimensions,
the Smart Connect
®
feature (Fig. 3.1)
assures leakage of liquids and/or
gases from inside the system past the
sealing element of an UNPRESSED
connection. The function of this
feature is to provide the installer quick
and easy identificaiton of connections
that have not been pressed prior to
putting the system into operation
(Fig. 3.3).
When the fitting is pressed, the
Smart Connect feature is reformed
and thus loses its effect (Fig. 3.2). A
permanent;,sealed, non-detachable,
mechanical connection is created.
Press systems without the Smart
Connect feature may not leak initially;
however, later they can unseat in
future system operations. The Smart
Connect Feature is designed to
protect from this potential risk.
3.2 Testing
All system testing shall be carried out
in accordance to the local code or
body having jurisdiction. Connections
may be tested to a maximum of 600
psi. All pipe or tube system testing
shall be pressurized to the maximum
pressure and length of time required
by the code or standard having
jurisdiction.
The Smart Connect feature is a quick
and easy way for installers to identify
connections that need pressing.
Testing for leaks using the Smart
Connect feature is not a replacement
for testing to the requirements of local
codes or standards.
Water Testing the Smart Connect
Feature:
When testing the system with water,
a pressure range of 15 psi – 85 psi
maximum is to be used. This test is
in addition to that required by the
project specification or local code. If
an unpressed fitting is found, check
to make sure fitting is fully inserted
before completing the press.
Air Testing the Smart Connect
Feature:
When testing the system with air, a
pressure range of 1/2 psi – 85 psi
maximum is to be used. This test is
in addition to that required by the
project specification or local code. If
an unpressed fitting is found, check
to make sure fitting is fully inserted
before completing the press.
