5.8 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 MIMS cable and the clip (see figure 2).
The tube clip should allow axial expansion of the MIMS cable.
■
Weld clips maximum every 300 mm [12 in] to 450 mm [18 in] of run alternating on
■
opposite sides of the sheath (see figure 2).
Force tube clips down after the thermocouple installation to ensure good sensor to tube
■
contact.
