I am a new user of PVElite. Can anybody tell me how to model female or groove flange which commonly used a channel flange and shell flange in PVElite.

Thanks

Hello Charlie

We really need a little more information. There are several flange configurations with grooves. It could be a tongue and groove type assembly, or there could be a groove in which a soft ring gasket is located where the flanges otherwise have flat faces. If you could kindly provide more informaiton or e-mail us direct at techsupport@coade.com we will then be able to give a more detailed answer.

The ASME VIII, Division 1 code for example has two appendices that deal with flanges. One is appendix 2, and the other is appendix Y. If you look at the illustrations these locations in the code, can you find one that fits your question?

I refered to a tongue and groove type assembly.

Hello again Charlie

If the flange has a tongue and groove type gasket, then it can be designed in accordance with ASME VIII, Division 1, Appendix 2. In this case you have to decide if it is an integral (weld neck), or ring type flange.

In PVElite, select a flange component from the icons on the top of the screen, then at the bottom of the screen, check the box that says 'perform flange calculation'. When the flange dialogue screen opens up, choose the most suitable type of flange from the thumbnail sketches at the top of the screen.

For a tongue and groove design, you have to enter the 'nubbin' (the tongue) inside and outside diameters. However, by using the 'F1' key when your cursor is in various fields, you will get help on what the various dimensions are.
