3.1 CUTTING AND INSTALLING CC129A COUPLANT SHEETS
Orientation of the CC129-1A is not critical. Cut the sheet to achieve the best coverage
and use of material. The full size (9" x 36") sheet may be difficult to apply. Cutting the
sheet to manageable pieces will not affect efficiency. DO NOT INSTALL TRANSDUC-
ERS ON SEAMS.
3.1.1 SIZING SHEETS FOR PIPES 6-INCHES AND UNDER
Cut the 36-inch sheet length in half. The 18-inch length will be applied along the axis
of the pipe.
Leave the sheet at the full 9-inch width for pipes over 3 inches in diameter. Cut width
as needed to avoid significant overlap on pipes under 3 inches in diameter.
Cut any additional sheets as required (see Table 1 for proper number of CC129-1A
layers).
3.1.2 SIZING SHEETS FOR PIPES OVER 6 INCHES
Use the full CC129-1A sheet dimensions. The 36-inch length will be applied along the
pipe axis.
Depending on the transducer size code multiple layers may be required. Refer to
Table 1 for the correct number of CC129-1A layers to apply.
3.1.3 APPLYING CC129A COUPLANT SHEET TO PIPE
Verify that the ambient and pipe temperature fall within the temperature limits speci-
fied below Table 1. Note that operating and installation temperatures are not the same.
Determine the proper location of the transducers (refer to paragraph 1 above).
Thoroughly clean and degrease the selected pipe area with a suitable solvent (see
Siemens Hardware
Cautions in para. 3.1.5).
