	NFPA-11 states that Galvanized CS is not allowed to be used for foam piping. The peremissible materials is CS / Austenitic st. st. The point is what is the effect of this media on the galvanized CS, which is considred a Coated CS while the uncoated CS can be used. It seems that it will cause a galvanic corrosion or something like this. ?????

	This may be a corrosion issue; i.e., foam and zinc do not "like" each other. __________________ In vino veritas; in cervisia carmen; in aqua E. coli.
