The intent of my original post was to seek help in determining why my static results would not indicate that the middle support is carrying some of the weight.Īn additional point of confusion is that when I add up the +Y reaction at all the supports, the total is roughly 150% that of the actual weight of the pipe + water during the hydro case. I've seen plenty of towers out there with piping expansion loops so I know this is not how it is always done. I do not want to simply beef up the top support and hang the entire piping load from it because my company's standard support is limited to only 2500 lb. #49164 - 06/07/12 06:34 PM Re: +Y vessel pipe support not taking load during hydrotest case Pipe normal operating temp is 225F, although this is irrelevant I suppose. Pipe design temp is 275F and vessel average oper temp is 235F. My understanding is that the middle +y support should be carrying some of the weight during the hydro case, so I need help determining why it is not. During the hydro case, my top support is carrying 6400 lb, and the middle support is for some reason carrying none. My company's standard vessel pipe supports can support a maximum of 2500 lb each. The pipe has a small horizontal run a little ways down the pipe for flexibility. Near the top of the vessel is a rigid support, halfway down is a guide with a +Y support, and near the bottom is another rigid support.

I've got a tower with a 10' vapor line coming out the top of it and running the side of the vessel.
