can any one email me PDAM:emad.farahani@gmail.com or upload it again
it would be appreciated

Hi all, I understand that the thread is quite old now. However, I am keen on reading this manual and thought its a good idea to request the group to kindly share the manual... could someone please email it to me on vslaser@gmail.com or post a link here? It would be great favor done by you if you could.

Thanks
Vijay

Thanks Sumon (for posting the document on PDAM) and Antonio (for e-mailing the PDAM document)

I am a new member in this group and I already find this a very helpful one. I will do my bit where I can in the group and try to be active in this one.

Thanks and best regards,
Vijay

Hi all,

I was wondering how a level 3 Finite Element Analysis (FEA) of pipeline defect compares with level 1 and 2 analysis based on various defect assessment standards (ASME B31G, RSTRENG and API 579) in terms of being conservative. What I mean is:

Is there a way of comparing the results of FEA based defect assessment with results of defect assessment based on these standards?

Any help will be great. I am new to pipeline defect assessment field so kindly pardon me for stupid questions.

Regards,
Vijay

good morning
First, it is not a silly question
what you ask is a little complex.
I give one example, a corrosion assessed by B31.G
for you to try to match the results, the FEA analysis should be considering the plasticity of the material, after this exceeded SMYS because B31.G considers that corrosion failure until the flow stress is exceeded.
another point is that the corrosion should have an elliptical shape in profile, because that's the way you think B31.G. if the shape is away from the elliptical shape, have major differences.
The B31.G only consider the stress are generated by internal pressure only if the FEA analysis applied load will exist other differences.
