How to get rid of extra geometry

Dissolved the 2 loops you mentioned, redirected edge flow around the back of the object...

BTW you have several modelling errors in that mesh. There are incorrect Normals, and non-manifold edges.

 

Of course even the 2 outer loops here will affect your circularity of the larger form because there is not sufficient geometry here to establish your curvature. Therefore you must either adjust those 2 loops so that they conform to the larger curvature of the form, OR don't extrude the top bit until you have applied 1 or 2 levels of subdivsion to the mesh, which would establish the curvature to the point where your extrusion wouldn't affect it and there would already be sufficient geo to not require any additional loops..

If you start the larger tube with 96 segments for example, we can fit that small detail in much more nicely with none disturbance to curvature...

  • I added some segments to the tube and it did the work. What is a non-manifold edges?

    You're welcome. NME's are edges that that have more than 2 surfaces connected to them. The ones in your model are highlighted red below, and are caused by the 2 polys inside them, which shouldn't be there.

  • What do you think about this technique?
