Fasteners and options for highly corrosive atmospheric environment
Fasteners and options for highly corrosive atmospheric environment
(OP)
I would like to learn more about what mitigation measures are used in a highly corrosive atmospheric environment, such as off-shore applications. The original design uses galvanized steel, with some aluminum parts and stainless steel fasteners. I am thinking the HDG may not be enough for such a corrosive environment.
Should the fasteners need be installed with protection caps? Should coating such as epoxy or polyurethane be applied to the entire assembled structures? Thank you.

Grease tapes like Densyl tape also work and allow you to encapsulate the entire flange. Don't get lazy with surface prep, grease tapes benefit just like paint.
There are also hot melt coatings that are peelable and work quite well. The initial investment is quite high for the application tool. Supposedly the coating is reusable, though.
