How to get a better union on those breps?

Hello there, I did this structure based on pyramids edges, but when I pipe them the joins are not good.

Is there a way that I could turn all this lines of each group in a single brep? I couldn’t do it with solid union

What’s the goal of this?

FYI 3D printing works with individual overlapping pipes and does not need a single brep.

If you really need this to join into seven single breps, my first suggestion is multipipe and then subd to brep.

If a single mesh is useful, shrinkwrap the nurbs pipes and use round caps on all of them.
