Galvanization is done on process piping to protect it from corrosion. Is galvanization possible only on threaded piping? If so, is it true that for some piping components, galvanization is mandatory but for some it is not?
Have an insight or suggestion?

Re: Is galvanization possible only on threaded piping?
14 November 2008 at 1:29pmGalvanizing is the process by which an adherent coating of zinc or zinc and iron is produced on the surface of iron or steel products by immersion in a bath of molten zinc. The zinc coating is anodic relative to the iron or steel and corrodes preferentially, forming a protective zinc-oxide layer. For more information try the book "Corrosion and Electrochemistry of Zinc" by Xiaoge Gregory Zhang (1996, Springer).
