Tube and Pipe, forcing a flanged connection

alan.wedge — Mon, 14 Feb 2022 14:25:38 GMT

Hi,

I am working with a custom tube and pipe profiles, these are socket welded and flanged. My pipe has to have fittings in the run that would be flanged on either side. I want the assembly to go into the BOM properly counting all flanges.

I cant seem to author a part that will place a flange on both sides of the connection, below is a test piece with flanged ends authored.

due to the need for all flanges to be counted, I don't want to design the flanges into the fitting as these would not be counted.

if the fitting is authored with a welded end, it just butt welds to the pipe.

is there a way of making this work or adding "fake" BOM lines to fill in for the missing flanges?

Thanks

Hi. I moved this from the iLogic forum. To get a flange on either side of a fitting placed inline on a route, the fitting has to be authored as having flanged connections AND your Tube & Pipe style must be set as a Flanged style with a flange and gasket (if needed) specified. Even with your main style being butt weld, you still need to specify that this is a flanged style for Inventor to know that you want flanges and gaskets added on either side of any fitting that meets to need. Does that make sense? I hope that helps.

my style is flanged and I have flanges and gaskets assigned correctly, it works fine when placing a break in the pipe. the fitting in the first screencap is authored as flanged but inventor does not place a flange on the fitting.

in the screencap, the pipe to the left, right, flanges and gaskets are all placed by tube and pipe, im trying to get inventor to place a flange on the fitting in the middle.

Ok, I think I see now. Sorry, I was not grasping your design intent. For what you are tring to do, you will either need to make the flanges a part of the fitting (which I know you do not want), or place the fitting and then add the gaskets and flanges on either side using Place and Insert. If you do that, you will want to change the Authoring of the fitting back to Butt Weld, and use a Butt Weld flange on either side. I'm afraid there is no way to make Inventor do this automatically. Authoring a fitting to Flanged only tells Inventor to put the gasket and backing flanges in, not to place flanges on the fitting itself. I'm linking to a quick Screencast of this. I used a BW Tee to simulate the fitting you have in your run, but the technique is the same. this will give you an accurate count of gaskets and flanges for your BOM.

thanks for the help, i will test a few workarounds and see what I can do.
