11. SANPRESS INOX (STAINLESS METRIC) PIPE AND FITTINGS 15 MM -108 MM
11.1 Viega Press Systems
Pipe
Only Viega Sanpress INOX piping is
approved for installation with Sanpress
INOX fittings. This is to ensure reliability
and conformity with the stainless steel
system. Sanpress INOX pipe comes in
sizes 15mm through 108mm.
General
Viega Sanpress INOX pipes are
schedule 5, inert gas welded pipe,
meeting ASTM A776 and DIN 316S.
Delivery Condition
All dimensions of pipe are delivered
in sticks that are six meters in
length, with a metallic bare exterior
and interior surface. The pipes are
free from annealing color, corrosion
promoting substances and hygienically
questionable substances.
All pipes have been tested for leaks.
The pipes are subject to continuous
monitoring, as well as external
monitoring by the material testing office.
Viega Press
Systems pipes offer
these advantages:
• Form-stable
• Prevent fire as no soldering or welding
device is required for
installation
• Press fitted in seconds
• Low in linear expansion due to heating
Identification
Viega Press Systems stainless pipes are
marked and labeled with the following
information along their entire length:
1. System vendor/system name
2. Test marks and approval marks
3. Material number in accordance with
DIN specifications
4. Pipe diameter x wall thickness
5. Manufacturing type g = inert gas
welded
6. Pipe manufacturer abbreviation
7. Manufacturing date
8. Lot or reel number
11.2 Handling Instructions
Sanpress INOX components shall be
free from dirt, debris, scaling, or items
that may interfere with the sealing
element and the press connection.
Sanpress INOX sealing elements are to
be visually inspected prior to installation
to ensure the seal is intact and properly
located within the fitting.
11.3 Welding Near
Sanpress INOX Fittings
When welding near a Sanpress INOX
connection, the installer must remain
at least three feet away from the
connection to prevent damage to the
sealing element. If three feet is not
possible, the installer should take
precautions to keep the Sanpress INOX
connection cool while welding.
These include:
• Wrapping the connection with a cold
wet rag
• Fabricating welded connections prior
to installing the pressed fitting making
sure the pipe has cooled before
installing the fitting
• Consistently applying “spray type"
spot freezing
11.4 Rotating a Pressed Fitting
Once a Sanpress INOX fitting has
been pressed it can be rotated (not
by hand), but once rotated more
than five degrees, the fitting must be
re-pressed to restore the resistance to
rotational movement.
