Hello rhv
Normally, the programme expects cylinders to attached to either end of a cone. This is because PVElite performs the cone analysis in accordance with Appendix 1-5 for internal pressure and Appendix 1-8 (ASME) for external pressure. However, you cannot directly install a nozzle in the end of a cone, but you can do the following to achieve the same result (assuminng you have a vertical vessel with a skirt support).
Remember, PVElite constructs the vessel from the bottom to the top.
1 start your model with the bottom nozzle, which is entered as a cylindrical shell. set the dimensions of this nozzle (shell) to the normal pipe size of your choice.
2 if there is a flange at the bottom of this nozzle, then add it by inserting is before the cylinder, and set its dimensions, or use the look up feature.
3 next, add the cone. At this point, you will have (if you look at the model on the screen), a cone with a flanged nozzle at the bottom (the nozzle actually being a cylinder component).
4 now add the skirt, and ensure its top and bottom dimensions are set to the correct diameters and that the skirt length is correct.
5 continue building the remainder of the vessel.
I know this seems somewhat long winded, but this method will achieve the result you want.
If you have a problem, you can alway 'phone me at 281-890-4566, and I can go through it with you.
