2.4.3 Determining and Marking the Second Nozzle Location - MR2 Mid-Radius (cont.)
Note:
For convenience, refer to Table 8 below for tabulated values of the AS dimension for some common pipe sizes.
For any values not listed in the table, calculate your AS dimension with the equations above.
5. Wrap the strip of film around the pipe with one corner edge lined up with the vertical and horizontal scribe
lines at the first nozzle location (see
Figure 56 below). Make sure the strip overlaps squarely around the pipe
and that the marked line on the film from step 4 is on the outside of the film and is visible when wrapped.
