Table below provides recommended correction factors for pipe support spans for different piping layout configurations. The correction factors are defined as a percentage of calculated pipe support span for straight run of pipe with a uniformly distributed load.
| Pipe Support Configuration | Pipe Support Span Correction Factor |
|---|---|
 |
If the calculated pipe support span for straight run of pipe is 'L' based on pipe span support calculations, the correction factor for this configuration is 0.7 and the recommended support span for the configuration is L1 = 0.7L. This recommendation assumes that the adjacent pipe supports follow the calculated pipe support span for straight pipe runs. The recommended span factor assumes no concentrated load between the supports. |
 |
If the calculated pipe support span for straight run of pipe is 'L' based on pipe span support calculations, the correction factor for this configuration is 0.85 and the recommended support span for the configuration is L1 = 0.85L. The vertical drop should be limited to L1/8. This recommendation assumes that the adjacent pipe supports follow the calculated pipe support span for straight pipe runs. The recommended span factor assumes no concentrated load between the supports. |
 |
If the calculated pipe support span for straight run of pipe is 'L' based on pipe span support calculations, the correction factor for this configuration is 0.65 and the recommended support span for the configuration is L1 = 0.65L. This recommendation assumes that the adjacent pipe supports follow the calculated pipe support span for straight pipe runs. The recommended span factor assumes no concentrated load between the supports. |
 |
If the calculated pipe support span for straight run of pipe is 'L' based on pipe span support calculations, the correction factor for this configuration is 0.75 and the recommended support span for the configuration is L1 = 0.75L. The vertical section at branch should be limited to L1/8. This recommendation assumes that the adjacent pipe supports follow the calculated pipe support span for straight pipe runs. The recommended span factor assumes no concentrated load between the supports. |
 |
If the calculated pipe support span for straight run of pipe is 'L' based on pipe span support calculations, the correction factor for this configuration is 0.9 and the recommended support span for the configuration is L1 = 0.9L. This recommendation assumes that the adjacent pipe supports follow the calculated pipe support span for straight pipe runs. The recommended span factor assumes no concentrated load between the supports. |
