I apologize if this topic has been discussed, but the search function is down and Google didn't pull up anything on this topic.
A paint spec says for carbon steel, "When using inorganic Zinc under insulation, do not apply on piping or vessels operating between 50F and 250F as the zinc reverses polarity and contributes to the corrosion of carbon steel."
May someone offer a link to a paper or article that further describes the problem with zinc coatings under insulation?
