Dis-similar piping materials / galvanic corrosion

What is the environment? If you are handling a fluid that is corrosive then yes, you will have galvanic corrosion issues.
The common approach is to have the stainless lined (such as with epoxy) for a distance from the interface and a little bit of the steel. You will also want to coat the inside of the joint itself.
On the outside of there is a chance for this pipe to get wet and it is near the sea coast then paint all of it.

I would suggest that you paint he outside of all of it.
It is even more important to paint if the pipe will be insulated.

as other suggest you've to paint the SS but also the CS 'cause in that atmsphere the CS will corrode also due to atmospheric corrosion.
If it's in florida and exposed to atmosphere with high chloride it could be a concern also SCC of Stailess Steel. I mean if the tube is exposed to the sun (i don't know the operating temp of the tube)can reach high temp and above 60°C there is a risk of SCC. it should something to be evaluated.

General corrosion of the CS, SCC risk of the SS. that is why it should all be painted.
