This assembly features a pipe passing through an interior stud wall or exterior surface partition using a sixteen-gauge galvanized steel sleeve secured grout-tight to the partition. The annular space between the pipe and the sleeve is filled completely with fire-caulk, specifically 3M fire safing. Where the pipe is exposed, an escutcheon plate is installed to finish the penetration, with the specific type coordinated with the architect. The pipe may include insulation and a jacket depending on the specific service requirements.
