Web1 dec. 2024 · The recommended velocities for fluids’ transportation must be updated periodically to obtain the optimum value of the pipe diameter in the current economic conditions To arrive at the optimum diameters for pipes, the heuristic criteria of recommended velocity has been used in the past. WebIf steel piping with a schedule 60 - 80 (being common values for gas and steam piping) is used with diameters of 6 - 10 in., the sound insulation value (R) is 44 - 48 dB for high frequency noise. The difference between PWL insand SPL1mis approximately 36 - 40 dB.
