Hi, I've a doubt. We've an application welding a round tube to a round flange with ribs (see image). We use to design this with clips in the ribs so the weld of the ribs do not go over the flange weld. But recently I've found a document from Corus with the detail in image. Welding on weld and recommending it to avoid corrosion problems. Now I'm not sure if there's any limitation in the structural or ASME pressure code to do or not to do one or the other (I haven't found anything but maybe I'm missing something).
Thanks very much,
