I am currently in the process of designing a charge air cooler pipe for a class 8 truck and I need some advice on which finish to spec for the part.
The pipe it's self will be ASTM A787 Type 1 aluminized steel but it will be welded to a ASTM A513 steel fitting. Typically the aluminized steel pipe wouldn't be welded and would be sufficiently corrosion resistant without additional coating but in this case I believe additional protection will be required.
The customer suggested an e-coat, which I was unfamiliar with, but now I'm getting the impression that an e-coat would only be a primer and not a top coat. Is that correct? An e-coat would be a good choice because it would coat the entire part, inside and out with a very thin layer of paint (0.02mm to 0.03mm, as I understand). Is it common to spec only an e-coat to finish a part? Would a colour be specified?
Any info or suggestions would be appreciated.
Thanks,
Mike
