WARNING!
Keep a distance of one meter to the fusion site during the fusion
process for general safety reasons.
The obtained
actual fusion time
is
to be compared with the
target
fusion
time on the unit and to be
noted on the pipe or the
FRIALEN
®
Safety Fitting
(See Figure 12).
With this identification it is ensured
that no fusion point is overlooked.
In case of doubt
, a fusion can be
repeated. But the joint surfaces
must be cooled down to ambient
temperature before each renewed fusion. Please contact for this purpose
your local FRIALEN
®
sales engineer by phone or the FRIALEN
®
Hotline.
4.10 Cooling times.
The cooling time is
a) the time which is required to cool down the component to the temperature
which facilitates the movement of the joint. This time is also listed on the
barcode and is identified by CT.
b) the time which is required to cool down the component to the temperature
which facilitates the application of the full test or operating pressure. This is
classified into pressure volumes of up to 8 bar and > 8 bar.
WARNING!
When inserting piping (e.g. relining) it is the cooling time before pres-
surising which is important.
