Corrosion between SS316 and Duplex 32205

The passive potentials are nearly identical, the 316 will go active more easily.
So the result is if you start to have some corrosion the 316 will see an accelerated rate.
Are they being welded or is this a mechanical joint?
How safe is the 316?
If the system would last for decades in all 316 then adding in some 2205 will not hurt anything.

I hope that these are either mechanically expanded plugs (Pop-a-plug) or welded.
A driven tapered plug is a very bad idea.
And yes, if there is any risk of crevice corrosion the 316 plugs will corrode and fail.
