Interesting engineer. Is he a real fire protection engineer or some other discipline. On the Ames IBR there are two appendages, one is a little nub at the turn for embedding in the thrust block concrete and the other is a SS tab with a hole for providing rod bracing out to the horizontal connection. I assume that your engineer believes that he needs dielectric connection between the SS and the pipe material that is connecting to the IBR. This is not necessary at all. We use these on all of our projects as I specify them, but I will tell everyone that on the last project we got a small hole in one of the IBRs either from a manufacturer's defect or corrosion. We suspect manufacturer's defect as the system was only in place for a year. Nevertheless, even the SS IBRs should be wrapped in 8 mil poly to be conservative.
