COPPER EXPANSION AND
CONTRACTION
See table below for precalculated anticipated expansion for various pipe sizes and lengths of refrigerant piping.
To find the anticipated expansion value:
1. From the table below, find the row corresponding with the actual feet of the straight pipe segment.
2. Estimate the minimum and maximum temperature of the pipe.
3. In the column showing the minimum pipe temperature, look up the anticipated expansion distance corresponding to the segment length.
Do the same for the maximum pipe temperature.
4. Calculate the difference in the two expansion distance values. The result will be the change in pipe length.
