7 Fusion
Operating instructions GF 500
16
Constant high pressure when facing, can cause damage on the drive and/or the
motor of the facer.
4.
Plane the facing surface of pipes/fittings until shavings are turned out
in ribbons which are the same width as the pipe wall thickness. The
max. planer pressure is 10 bar above the drag resistance.
To make sure the gap and the wall offset are in order, both sides must always
be planed!
5.
Switch facer off.
Z
Remove facer of the machine and place in the case.
6.
Close machine until pipes/fittings. Touch each other. Maximum
tolerance of the gap is 0.5 mm.
7.
Check the alignment at the same time.
8.
The wall offset on the outside may not exceed 10 % of the wall
thickness.
9.
If it is larger, the pipe/fitting can be turned or the clamping force
on the inner clamping units can be changed to achieve a better
clamping position.
10.
In this case, the fusion surfaces need to be remachined.
11.
Remove shavings which have fallen into the pipe e.g with a brush.
Before each fusion, the fusion surfaces must be cleaned with lint-free
paper and grease-free cleaner, e.g. industrial alcohol (Tangit KS).
Never touch the fusion surfaces with your hand after cleaning!
