Figure 3-1 Closing the chain around the pipe
7.
When preparing the ChainSCANNER for larger diameter pipes, the scanner’s
position must be adjusted, to avoid helicoidal movement as much as possible.
Otherwise, go directly to step 8.
For larger diameter pipes, adjust the scanner’s position. Do the following:
a)
Measure the distance between the side of the wheel of the module and the
weld (for example, 100 mm).
b)
Rotate the module 180° around the pipe.
c)
Measure again the distance between the side of the wheel of the module and
the weld (for example, 120 mm).
d)
Unlatch the chain mechanism while keeping pressure on the latch, to make
sure that the ChainSCANNER stays at its current position.
e)
Move the module to position it at the same distance to the weld as measured
in step 7.
(as per this example, we would move the module 20 mm toward
the weld).
f)
Latch the chain mechanism.
g)
Return the ChainSCANNER to it’s original position (180°).
h)
Repeat steps 7.
until the position is repeatable within an acceptable
range.
