1.1 Scanner Components
The COBRA scanner components are probes, wedges, probe supports, various link
types, tails, and crossbars. Figure 1-2 on page 16 illustrates a two-sided scanner
configuration laid flat.
You can configure the scanner to fit on a specific pipe outside diameter by assembling
the appropriate number and type of links. The tail and probe-holder parts also
include diameter fine-tuning adjustments. Refer to the scanner setup charts for details
(Table 15 on page 65 for pipe OD smaller than 2.50 in. and Table 16 on page 66 for
pipe OD larger than 2.50 in.). Pairs of wedges with appropriate curvatures are used to
cover the pipe outside-diameter range (see Table 7 on page 55 for the wedge selection
chart). Graduated crossbars are used to adjust the distance between the wedges.
Figure 1-3 on page 17 illustrates the various types of COBRA scanner links.
