Dear austsa, It is like a stand pipe but my client calls it stilling well. This stilling well does not have holes.

Dear pennpiper, I usually use a three point guide for stilling well pipe, but, for this case, my client specified a nozzle in the top and other in the botton of the vessel. The stilling pipe will be between these nozzles and it will be welded. I can´t use a guide for this case.

I need to install a stilling pipe (stand pipe) inside of the vessel. It will be welded in the botton and in the top inside of the shell. For a safe design, what kind of calculation I need to do? An Expansion bellow will be required in the stilling pipe? The internal pressure will be 25bar.

Material Stress Hot = Allawable stress at design temperature Material Stress Cold = Allawable stress at Ambient temperature See ASME II Part. D

Excuse me for not explaining right. I want to calculate the blind cover of a lifting lug to use for lifting a vessel. The blind cover is bolted to a top vessel flange. I need to know which condition I have to use: edge simply supported or edge fixed as boundary conditions for my model.

Colleagues, to design a base plate for a top flange lug, I want to use formulas for flat circular plates of constant thickness of Roark’s Formulas for Stress and Strain Ed. VII. Which condition I need to considerer for this calculation: edge simply supported (like cases 16 and 20 of Roark Ed...
