Thank you Dave for the calrification, 

yes it is needed to check for resonance, 

I have many flanges on the pipe let's say 5, so I run different cases for example, pipe in contact with 1 flange and not the others, then with a different one then with 2 flanges... etc, 

Do you think that will be enough to cover all possible aspects? 

As i understood when the pipe is not in contact with flange it's as if the flange is not existant, so might as well remove all non contact flanges from my model.
