Cutting and installing couplant sheets
Orientation of the damping material is not critical. Cut the sheet to achieve the best coverage
and use of material. The full size (229 mm x 914 mm / 9" x 36") sheet may be difficult to
apply. Cutting the sheet to manageable pieces will not affect efficiency. DO NOT INSTALL
SENSORS ON SEAMS.
Sizing sheets for pipes 6 inches (15.24 cm) and under
1. Cut the 36-inch (91.44 cm) sheet length in half. The 18-inch (45.72 cm) length will be
applied along the axis of the pipe.
2. Leave the sheet at the full 9-inch (22.86 cm) width for pipes over 3 inches (7.62 cm) in
diameter. Cut width as needed to avoid significant overlap on pipes under 3 inches in
diameter.
3. Cut any additional sheets as required (see table above for proper number of layers).
Sizing sheets for pipes over 6 inches (15.24 cm)
1. Use the full sheet dimensions. The 36-inch (91.44 cm) length will be applied along the
pipe axis.
2. Depending on the sensor size code multiple layers may be required. Refer to table above
for the correct number of layers to apply.
Applying couplant sheet to pipe
1. Verify that the ambient and pipe temperature fall within the temperature limits specified in
table above.
2. Determine the proper location of the sensors (refer to paragraph "Cutting and installing
couplant sheets" above).
