I have axial load(tensile/compressive) and longitudinal and circumferential bending moments at nozzle/shell intersection. Axial load is along centerline of nozzle, circumferential and longitudinal are along tangential axes at shell.
I need to check flange on a nozzle and for that the loads need...
Does anyone have experience applying NBC 2005 Seismic Code to pressure vessels? I am looking through it right now but am unclear at the moment to its application to vessels and towers.
Any help is appeciated.
Thank you in advance.

Could someone please explain:
1. Zero Period Acceleration
2. Zone factor
Their relation to each other if any (formula).
Thank you in advance.

Could someone please highlight the difference between Response Spectrum Method and IS:1893 RSM (2002)?
In particular, I am interested in how IS:1893-2002 could be alternatively modeled using Response Spectrum Method.
Thank you in advance.

Where can I read about Seismic calculations?
In particular I am interested in calculating reactiong at base of the support skirt and how it is derived?
Thanks and regards,

Hello,
I noticed that when modeling compress the set datum offset, accounts for straight flange length. Could you thorw more light on the functioning of the datum.
Thanks in advacen for your comments.

Greetings group,
When designing a trunion, if there is overstress in the trunion near shell (branch at junction), should the pad thickness be increased or should the pipe thickness be increased. From my understanding it should be the pipe whose thickness should be increased, and it should be...
I have a vessel with upper shell and upper shell.
I wish to break it down to 15 cylinders of smaller size.
What is the fastest way of doing it without redesigning it?
I tried insert and it shows the insert after, but it doesn't insert when I select my shell.
Is there may be a split option...
Hi all,
Could someone tell me how to hand calculate bending stress of a pressure vessel during lifting/rigging analysis.
I am using the following, please let me know if this is correct approach:
1. Solving forces and moments for Equilibrium.
2. Calculating Bending Moments at each force
3...
Hello,
I have just started freshly with pressure vessels and am slowly learning it.
Could someone please tell me what calculations are required for a tall vertical vessel lift using 2 trunnion w/ 1 tailing lug and which standards to follow?
Thanks
