About this detail

Supply and return connections for an air handling coil in a critical environment above the ceiling. The schematic layout features isolation butterfly valves, line-size flex connections, circuit balancing valves with positive shut-off, modulating control valves with spring return, and a Y-strainer with a three-quarter-inch hose end drain valve. Thermometers with thermo-wells and manual air vents are included at required high points. A separate riser support detail shows a one-and-a-half-inch pipe terminating with a pipe cap, supported by a one-inch-by-four-inch threaded rod welded to a four-by-four-by-one-eighth-inch steel plate over a half-inch waffle pad, with a one-inch nut welded inside the pipe.
