6.9 Tube clip welding
Attach clips at predetermined locations. Preheat area before welding, if required.
■
Weld the first tube clip at 100 mm (4") from the guide channel, weld only on the opposite
■
side of the guide channel (see figure 2).
Weld tube clip on one end only and ensure there is a loose fit (no friction)
between the mineral-insulated cable and the clip.
The tube clip should allow axial expansion of the mineral-insulated cable.
■
Weld clips maximum every 300 mm (12") to 450 mm (18") of run (see figure 2) alternating
■
on opposite sides of the sheath.
Force tube clips down after the thermocouple installation to ensure good sensor to tube
■
contact.
