Association problem meshing coil pipe
 

I am trying to mesh a coil pipe as in figure
I always face this mesh problem like there is a conflict in association like in figure attached
I tried to dis associate and then re associate but it did not work
could any one help please?

Youtube tutorial available for the same
 

There is a Youtube video available already on a similar geometry and meshing where they have explained the association part. The mesh seems reasonable, so you can follow the same.

Alternatively, only mesh the T-junction and then extrude the mesh on the ends of the T-junction along the curve/spline of the coil. Much easier.......
To extrude a mesh look for the second or third Icon in Edit Mesh-menu
