1) The maximum loads in the table above are based on allowable tensile stress of 12 kpsi - reduced by 25% to 9 kpsi allowable stress.
- 1 kg = 9.81 N

- Mass and Weight - the difference
Note that hangers supporting steam, water, air or gas piping systems should be able to carry the weight of piping, insulation, valves and other equipment - and water for hydrostatic pressure testing - without exceeding 80% of the supporting hangers yield strength (not exceeding 16 kpsi for steel of unknown properties)
