Plus impact load, thermal loads, expansion, contraction, vibration. The intention of the minimum deflection value is for drainage and process flow (empty the pipe when done) requirements between the most common support methods.Ī 'pipe' is fighting its own weight, its fluid's weight, its insulation weight, and the valves, fittings, and extra snow/ice/wind/etc loads that happen to fall on the thing up when it is vunerable up in the air.
