Section 8: Pipe Support
Depending on the complexity of the piping network, various pipe supports are needed to hold
and support the piping along its route. Such supports will include hangers, saddles, trays,
brackets, anchors, etc.
These supports must be strong enough to withstand all static and dynamic load conditions, which
include:
a. The weight of the pipe, fittings, valves, water and insulation material
b. Wind, ice and seismic forces (where applicable)
c. Vibrations and water hammering
d. Forces imposed by thermal expansion and contraction of the pipe bends and loops
Generally, the pipes from the mini chiller unit are run along the ceiling space, along wall surfaces,
through floor slabs, through walls and also along the floor level. The following diagrams give
suggestions on how various pipe supports are used for the different type of applications.
Other than that, the number of supports must be sufficient along the pipe length to prevent the
pipe from sagging. The spacing between supports will depend very much on the pipe material and
the pipe size.
"Softer" pipes, e.g. PVC and copper, will require shorter support spans.
Refer to the attached table for suggestion of this support/hanger spacing.
