Pipe error/ Fillet the sharp edges

Dear all,
I generated a wave curve along an arc. I did that in such a way that the frequency height and width can be parametrically controlled. I want to extrude using Pipe modulue, I can see that the individual curves generate extruded pipes which are overlapping at the edges. So I flatter the curve so it is a single and I cannot use pipe radius beyond a certain value. I also used prep frames and generated circles along the curve and use loft option. Again the same problem.
Please help me out as I would like to have fillet at the edges marked in the figure!!
