internal pipe support stress

internal pipe support stress

internal pipe support stress

i have a case that i need to put internal pipe inside the vessel and pipe need to be supported on the vessel head bu structure support . client is asking to study the stresses on the roof due to this structural support . i got the reaction forces from structural engineer but i couldn't consider it as external forces because we need to study the local stresses on the attachment area .

RE: internal pipe support stress

And what is your question???

RE: internal pipe support stress

You would analyse the local stresses on an internal attachment much the same as an external attachment. There are just acting on the other side of the shell. FEA would deal with this no problem. Manual calculations will need add the shell pressure stresses in the correct direction.

That sounds much to simple for eiadro1. He wants a much more complicated method!!!

RE: internal pipe support stress

You need to consider lamellar tearing in head.


RE: internal pipe support stress

i already tried to attach clip or cleat and apply the same forces but this will not test the stresses due to welding on the head which my client is looking for - i tried alternative manual calculations in structural steel standards AISC to check the stresses on welding area between structural parts it gives a massive margin different from what i got by applying external clip .
