Pipe Support Spans: copper
cu 3 typeL steam to cu 4 typeL water
Maximum allowable horizontal pipe support spans — maximum spacing between supports for straight horizontal runs by pipe material, NPS, schedule, and service (water, steam/gas/air). Per MSS SP-69 and ASME B31.1 Table 121.5. Covers carbon steel Sch40 (1/2"–24"), stainless steel Sch10S (1"–12"), copper Type L (1/2"–4"), PVC Sch40/80 with temperature correction, CPVC Sch40/80 with temperature correction, and FRP standard wall.
