The correct and economical selection of the supports for any piping system usually
presents difficulties of varying degrees, some relatively minor and others of a more
critical nature. Proper support selection should be the objective of all phases of
design and construction.
Many pipe support problems may be minimized or avoided if proper attention
is given to the means of support during the piping layout design phase. The piping
designer’s familiarity with support problems, accepted practices, and commercially
available pipe support components and their applications is extremely important.
Good pipe support design begins with good piping design and layout. For example,
other considerations being equal, piping should be routed to use the surrounding
structure to provide logical and convenient points of support, anchorage, guidance,
or restraint, with space available at such points for use of the proper component.
Parallel lines, both vertical and horizontal, should be spaced sufficiently apart to
allow room for independent pipe attachments for each line.
Pipe support specifications for individual projects must be written in such a way
as to ensure proper support under all operating and environmental conditions and
to provide for slope, expansion, anchorage, and insulation protection. Familiarity
with standard practices, customs of the trade, and types and functions of commercial
component standard supports and an understanding of their individual advantages
and limitations, together with knowledge of existing standards, can be of great help
in achieving the desired results.
