Hi,

which caclulation code are you using for the calculation?
Also it matters, which presetting for a normal node you chose, in the standard setting ROHR2 creates a welding node:

Hi,

the component "VUU" is a untreated butt weld, not a the straight pipe. As normally the user doesn't insert all the assembly welds, ROHR2 creates a weld at each node.
If you don't want this, you either can change at for a node afterwards by double clicking and selecting "PGR" or you can change it in the project setting as shown above.

best regards,
