I'd think it would move similar to a deluge valve when the pumper hits it. How about hilti hdi-p drop-ins with rod up to riser clamps, with galv pipe nips over them. Allows maintain pitch.

Running the pipe through the hall way to 4 standpipes is particularly difficult. An option is to run galvanized pipe on the flat concrete roof to connect all 4 risers to one FDC. Pipe will be supported on blocks with grooved ells and tees. Does this pipe require restraint anchoring to the concrete roof deck? If so at what spacing?
