The fusion surfaces of the parts to be connected
should not be damaged or contaminated (e.g.
with swarf, grease, dirt).
The REHAU electrofusion couplers are to be
stored in closed rooms in the original packaging
away from the effects of weather such as e.g.
moisture. The storage temperature should be
between 0 ° and 40 °C.
10 Assembly steps
10.1 Cutting the pipes
Suitable equipment for plastic pipes is to be used
for cutting the pipes.
Deburr the pipe separated at right angles.
Fig.1 Incorrect welding
If pipes are not cut at right angles overheating
can cause uncontrolled melt formation and lead
to defective welding (see Fig. 1).
In the event that the end of the pipe becomes
conical, it is to be ensured that at the intended
insertion depth the unprocessed pipe demon-
strates the nominal diameter at least in the area
of heating coil. Pipe ends which do not fulfil this
condition must be trimmed accordingly.
10.2 Marking the fusion area and mechani-
cal processing
Fig.2
Mark the insertion depths (half a coupler length)
on the ends of the pipe. Remove dirt from the
fusion surfaces beyond the fusion area and dry.
Fig.3
Immediately prior to assembly the oxide layer is
to be completely removed from the pipe surfaces
using suitable rotary peeling devices.
If the oxide layer is not completely
removed a leak-tight welded joint
cannot be guaranteed.
