Modelling problem

Hello!

I need some help regarding a modell i made. First I made a simple tube, then i created spiral cuts on the surface inside, with parameteres, so i can change the number of the spirals, the number of the turns of the spirals and of course the shape of spiral cuts. Now i would like to make from the straight tube also a spiral, a spiral tube. So i would like to have a spiral tube and on the surfafce inside the spiral cuts as i wrote. but the problem is that i can not make it with different number of turns. It works only if the spiral tube and the spiral cuts inside have the same number of turns. Could someone help? Is it  possible somehow for example "to turn" a straight tube?

On the pictures you can see my problem better. The two tubes i would like to "unite". Please Help!! Thanks in advance!
