7.2.2 Connecting RAUPEX pipe
Before beginning installation, refer to
Section 5.2 Fitting Assembly.

7.3 RAUPEX Pipe Packaging
RAUPEX pipe coils are shipped in cardboard boxes to protect them
from UV radiation, rain, dirt and other hazards. Straight lengths of
RAUPEX pipe are packaged and shipped in black polyethylene bags.
Keep pipe in the original packaging until it is required for installation.
Return unused pipe to the packaging.
Avoid the following:
- Dragging pipe over rough objects
- Contact of pipe with petroleum products such as oil, gasoline, paint
thinner
- Exposure of pipe to soldering or any open
fl
ame
- Excessive or permanent exposure to UV radiation
7.4 Fittings Packaging
fi
ttings and sleeves are shipped in cardboard boxes to
protect them from UV radiation, rain, dirt and other hazards. Keep the
products in the original packaging until they are required for installa-
tion. Return unused products to the packaging for storage.
Fittings and sleeves must be handled with care. At a minimum, avoid
the following:
- Storing loose
fi
ttings in tool boxes
- Contact with oil or oily products such as gasoline, paint thinner,
glues or solvents
- Exposure of polymer
fi
ttings and PEXa sleeves to soldering or any
open
fl
ame
- Excessive or permanent exposure to UV radiation of polymer
fi
ttings
and PEXa sleeves
7.5 Uncoiling Pipe
For best results when installing RAUPEX pipe from a coil, use a
REHAU approved uncoiling device. This will allow the pipe to lay
fl
at
(not twisted) when installed. Twisting the pipe may place stress on the
pipe after installation.
RAUPEX may be taken from a coil without the use of an uncoiling
device. When using this method, be sure to roll the pipe from the coil.
Do not lay the coil
fl
at on its side and pull the pipe up over the side of
the coil as this will twist the pipe.

7.6 Bending Pipe
RAUPEX pipe may be bent, with and without the use of a pipe bend
support. The minimum bend radius for RAUPEX in a standard
installation is five times the OD of the pipe.
RAUPEX may also be heated to achieve a minimum bend radius of
three times the OD of the pipe. A heat gun may be used to heat the
pipe. Heat RAUPEX and bend slowly. Once the RAUPEX is bent,
remove the heat source and secure the RAUPEX. Avoid overheating
RAUPEX (brown discoloration) and do not apply direct
fl
ame to
RAUPEX to heat it (from a soldering torch, for example).
