In oil & gas applications, inside the system, corrosion effect is considered to be less than that of existing outside viz. considerations of the environment, in contact with air. In view of that, various tables in ANSI/NACE MR0175/ISO 15156-3:2015(E) shall be referred, for the queried material...
Titanium to Aluminum corrosion will happen. Aluminum will get corroded. As surface area of Aluminum is more, the situation is time dependent. If application does not allow any risk taking, please avoid this galvanic couple.
