How far apart should the supports for copper pipes and tubes be placed?

The recommended intervals are set out in Table 1. Studying the table will show that fewer supports are required on vertical runs. This is because the vertical tube will not be subjected to possible sagging between supports. Excessive sagging will occur on horizontal runs of pipes made from any material if the supports are too far apart.
