Pipe supports are usually indicated on isometric drawings as a "PIPE SUPPORT CALL OUT", and consists of a combination of letters and numbers and indicates the type of support to be applied; see below...
Support for a pipe at a location can be a combination of standard support types or special pipe support. These designations should be written as separate items. For example, a pipe support frame that supports multiple pipes is indicated on only one isometric pipe drawing. For all other pipes, the isometric pipe drawing is referenced with the designation "PIPE SUPPORT CALL OUT".
Special pipe supports are indicated on the pipeline isometric drawing. All parts, including standard support items, are indicated on the separate special pipe support drawing. No support items are indicated on the piping isometric. A special pipe support is called SPS, and stands for Special Pipe Support.
The span between supports depends on the load, size, temperature of the fluid and material of the pipeline. Guides support vertical pipes. The following should be considered when calculating the span.
Refer to the table on this page showing normally good pipe support spacing for different materials. These requirements vary from company to company.
Material selection for supports and their components is determined by the design temperature of the pipe and applicable regulations. When selecting the material for the primary support, we must ensure that it is of compatible quality, if not the same as the pipe.
