Corrosion of a fittings in a stainless steel vessel
Corrosion of a fittings in a stainless steel vessel
(OP)
I am testing a structure inside a stainless steel vessel filled with sea water. The structure has a brass fitting and several titanium fasteners. Neither the fitting nor fasteners come in contact with the vessel or each other but will be aprroximately 1 foot away from the vessel walls and each other.
Will the brass fitting or titanium fasteners corrode? If so, can I use a sacrificial anode such as zinc to prevent corrosion? Is their any other way to prevent corrosion or isolate the fittings and/or fasteners?
Thanks for the help!

-The structure is plastic (non-conductive)
-There are no direct metal-to-metal contacts or any other electically conductive paths betweeen dissimilar metals aside from the salt water
My main question is whether dissimilar metals will produce a galvanic pair when immersed in salt water but not in direct contact.

It would be advisable to install a sacrificial anode in the tank. Two dissimilar metals in a salt solution constitutes a battery and the inferior metal will deplete. I sometimes used to put a piece of junk metal in a tank to feed the negative ion monster. Crude , but it works and ok if it does not contaminate your processs.

I am more concerned with the brass simply corroding on its own.
