    That will be the oxide layer. Steam strips every last molecule of preservative from the surface of the steel. But the hot dry environment prevents corrosion forming. So you just get that thin layer of oxide that forms very quickly when the system is depressurized and moisture forms on the surface. A bit like degreasing steel with acid. If you dont apply something to the surface rust will form in minutes

    Not sure what I am looking at in regard to the steam drum. Is that the inside of something like this?

    I figured we were looking at the flame chamber and the water was along the sides. ??
