I am attempting to refinish a wall however a rusty pipe causes a rust stain to constantly appear. Is there any way to cover over the rust spot to ensure that it does not come through the paint?? Should I use Kilz and if so which type is the most appropriate??

Welcome to the forums!
Most any solvent based primer will seal the stain. Oil base kilz will work.

If the rusty pipe is a continuous source of staining you'll have a fight stopping the stain.You really need to address the pipe itself.
rusty suggests steel and if that's an old piece of plumbing you may have a pipe that is in the process of failing.Old galvanized steel plumbing commonly eventually rusts through or fills with internal rust and becomes weakened.
As for the paint aspect if nothing else you might want to try and either prime and paint the pipe,figure out a way to block it's rust from contacting this wall etc.

Good advice on insulating the pipe in that area to reduce sweating which is likely contributing to the proliferation of the stain. I find Zinnser Stainkill a much better product than Kilz for permanently shielding this problem. Two or three coats of Stainkill and I think you'll find the stain stays gone.
