: What is the reason that galvanized pipe is not permitted in Boiler Blowoff and Blowdown systems ?
: (See ASME B31.1 "Power Piping Code" para. 122.1.4 )
: Is the reason because the zinc coating will pose a health hazard as it degrades due to high temperature or is there another reason ?
: Thanks in advance !!
: MJC
Operating pressure for one, certainly is a limit.
