Anchor Chair Repad-API 650 tank
Anchor Chair Repad-API 650 tank
(OP)
Hello Everyone
I wonder if any one can advise a reference to help in sizing the repad at anchor chair. Repad sizing is required by a third party inspector. Repad was selected due to high stress at shell caused by anchor chairs.>25,000 psi.
Best Regards

As an approximation, treat the repad as an anchor chair of equivalent height and width.

Is there any document or standard to be used in repad sizing , as this sizing is required by third party inspector and approximation won't work. I know ASME VIII Div II has these calculations for pressure vessels.
Best Regards

The approach typically used is listed as a reference in API-650, I believe- books put out by AISI.

I have had the same question. I'm still looking for a good reference that will direct me in the design of these repads. CHeck out this thread I posted a long time ago.

That is a very, very unusual situation. Have you considered increasing the height of the anchot chair?
