Axial Stress Computation by CAESAR II

Hi,

I would like to confirm if CAESAR calculate axial stress using the ID of the pipe and not the OD? Or if we need to activate something to do this.

Thanks!

If you're talking about F/A, then "A" is the metal area and both the ID and the OD are used to determine this.

If you're talking about the longitudinal pressure stress, you can find this equation in the Quick Reference Guide:

Slp = P x Di^2 / ( Do^2 - Di^2 )

So again, both ID and OD are used.

Thanks Richard,

I understand it is the metal area (or FRP), what I mean is if CAESAR considers the ID as less the corrosion liner thickness for axial stress computation.


Thanks!

"Maybe", it depends on the Piping Code in use. Some Codes consider corrosion and some don't, or don't in certain load cases. You can always force c2 to use corrosion by setting the "All Stress Cases Corroded" flag on the "SIF & Stress" tab of the Configuration Module.
