Micah, You need to consult with the MRI manufacturer, need to determine if a super-conducting magnet also need to determine radio frequency shielding requirements for the sprinkler pipe entering the MRI room (or any other opening into the room) check to see if "mu" metal shielding is being installed to reduce the effects of the magnetic field.
All penetrations of the RF shield need to have RF shield guides around the penetration. Have a fire safe day.

This is a new one for me. Does anyone have some insight into the kind of protection for the piping we would need to provide? Are we talking about a dielectric union or something?
