2.1.3 Installation of Flanges

When welding the flange tubes it is recommended to have the
Flange Alignment Kit (see Appendix G). The Flange Alignment
Kit from Siemens consists of a light source, two flanges, an aim-
ing tool, a battery and a battery charger for the light source.
Make sure there is enough room for the sensor. Especially take
into consideration that it should be easy to mount or dismount
and that the sensors lid should be able to open fully. Safe work-
ing space around the sensors are also needed, guardrails, lad-
ders, etc. The sensor dimensions are described in 2.2 "The Sen-
sors" on page 8. Figure 2.3 illustrates the process for installation
of flanges.
Installing the Flanges
Figure 2.3 Installation of flanges.
1. Weld the flange tubes loosely on each side of the wall. Do not
weld them so hard that the angle of the tubes can not be
adjusted with a hammer.
2. Mount the light source on one flange and the aiming tool on
the other flange (as illustrated in Figure 2.3).
3. Turn on the light source.
4. Adjust the focus on the aiming tool until the light spot from
the light source is sharp.
5. Adjust the angle of the process flange tube, using for instance
a rubber hammer, until the light spot is centred on the cross
hair on the aiming tool.
6. Weld the aligned flange tube permanently into this position.
7. Shift light source and aiming tool and repeat the procedure
above for the opposite flange until the other tube also is per-
manently welded.
