Pipe Support Spans: frp
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.
| pipe material | record id | notes | nps in (in) | schedule | service | span ft (ft) | span m (m) |
|---|---|---|---|---|---|---|---|
| frp | frp_12_std_water | Filament-wound FRP/GRE; liquid service | 12 | Standard | water | 26 | 7.9 |
| frp | frp_1_std_water | Filament-wound FRP/GRE (epoxy); liquid service; Sch A-per ISO 14692 | 1 | Standard | water | 9 | 2.7 |
| frp | frp_2_std_gas | Filament-wound FRP/GRE; gas/air service; lower density reduces required span | 2 | Standard | gas | 17 | 5.2 |
