Corrosion Behavior between Titanium + CuNi materials

[Calidad]

Dear Collegues:

I'm working in a project to study which it would be the effects of use in a heat exchanger bundle, tubes in CuNi (90/10) and tube for tie rods (spacers ) in Titanium mat (Class I or II) taking in account that spacers are closer to tubes (distance aprox 1 pitch = 19 mm ). Could exist a problem of galvanic attack or another kind of corrosion?.

Hoping by the opinnion of masters in matter, thanks in advanced.

Hello Collegues:

Thanks for your promptly answer. To complete my search, aand pay special attention to comment from MetalGuy, the referred enviroment is a heat exchanger that works in shell side (ext. of tube) with seawater at 4 barg and T aprox. 24 C degree.

Thanks in advanced
