Installation Instructions
CC129A-7
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 TRANSDUCERS ON SEAMS.
3.1.1 SIZING SHEETS FOR PIPES 6-INCHES AND UNDER
zCut the 36-inch sheet length in half. The 18-inch length will be applied along the axis of the pipe.
z 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.
z 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
z Use the full CC129-1A sheet dimensions. The 36-inch length will be applied along the pipe axis.
z 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
z Verify that the ambient and pipe temperature fall within the temperature limits specified below
Table 1. Note that operating and installation temperatures are not the same.
zDetermine the proper location of the transducers (refer to paragraph 1 above).
z Thoroughly clean and degrease the selected pipe area with a suitable solvent (see Cautions in
para. 3.1.5).
