Piping is supported either from above by the use of hangers or from below by resting supports. When routing piping indoors, run the piping close to structural steel in order to attach the pipe support steel to it.
When piping is run outdoors in groups, as in the case of a refinery, or chemical plant, it is usually supported on a piperack. If run individually there are a number of standard support designs that are in common use.
In the majority of industrial jobs, pipe supports are designed and fabricated by the engineer, however, most supports are also available commercially from a pipe support supplier such as Anvil, Lisega, AAA etc.
The design of pipe supports is covered in the various piping codes. Below is an excerpt from B31.1, note the reference to MSS SP-58 which is the standard covering ‘Pipe Hangers and Supports – Materials, Design and Manufacture’.
