Maximum Pipe Span
It is obvious that piping needs to be supported, the question is, what is the maximum span between supports for a particular sized pipe with carrying a fluid of a given density. The important considerations are:
- The maximum deflection of the pipe
- The maximum bending stress in the pipe
It is usual to limit the maximum deflection between spans to about 2 mm and the maximum stress should not exceed about 50MPa. The allowable stress will depend on a number of factors including:
- The design code applicable
- The piping material
- The design temperature
- The presence of other forces and moments
- Any stress intensifiers in the region
The above factors can be checked by doing a full and thorough pipe stress analysis. If you need a pipe stress analysis, please feel free to contact us with your requirements and we will be happy to prepare a proposal. Please send an email to stating your requirements.
