About this detail

An HVAC piping connection assembly with supply and return lines ties to air handling equipment above the ceiling in a critical environment. The piping includes a modulating control valve with spring return, circuit balancing valves with positive shut-off and memory stop, isolation ball valves, line size flex connections, thermometers with thermo-wells, a Y-strainer with a three-quarter-inch hose end drain valve, manual air vents at high points, and Pete's plugs. A separate riser foot detail shows a one-and-a-half-inch pipe cap welded with a fillet weld to a one-inch-by-four-inch anchor threaded rod welded to a four-inch-by-four-inch-by-eighth-inch steel plate resting on a half-inch waffle pad. The riser extends to within approximately eight inches of the floor and features a nut welded inside the pipe.
