I am new to the pressure relief valve world and having an issue on a relief valve that has already been installed. The valve is a conventional relief valve for pipe thermal relief of vapor and the outlet is piped to a vent. The capacity of installed valve is about 4 times of the flow rate...
I noticed that the equation for foundation bearing stress calculation for the skirt base ring design is different from the referenced book by Jawad & Farr. Is this an error or there is some reason behind the change? Thank you,
I am working on a stress analysis for a leg supported vessel with vacuum and seismic load. Due to the vacuum and the bending moment resulted from the seismic load, the area above the leg sees axial and hoop compressive stress. I am having a hard time for the buckling check and I hope I can get...
I am trying to use Compress nozzle FEA for nozzle analysis. The nozzle loads are given as due to weight, thermal, and seismic.
In compress nozzle FEA, there are input conditions for weight, operating, occasional and thermal.
My understanding is that nozzle loads due to weight will be input...
We are doing some burst tests for manway pressure rating. The maximum test pressure is usually limited by leaking from gasket before reaching the desired pressure. As a result, we will get a lower rating pressure for the manway although the steel components may be able to stand much higher...
I wish some expert here can shed my some light on using stress-strain curve for elastic-plastic analysis in Section VIII, Div 2. 2007.
Div.2 Part 3 provides the true stress-strain curves for materials. Part 5 requires to use the curve up to the true ultimate stress. Does this mean I need to...
I am using FEA to analyze the bolts of a plate heat exchanger based on the elastic stress analysis in Section VIII, Div 2. The loads include preload, pressure and thermal. 90% of the total stress is due to the operating pressure. I did the stress linearization for the bolts. The membrane stress...
We need to determine the size of a off-centered agitator shaft with no bottom steady bearing. We are concerned about the fatigue issue because of an additional bending force due to the off-center. Can anyone help on how we can estimate that force without CFD or how much bigger the shaft probably...
