Steam Pipes - Heat Loss (W/m)

Heat loss from un-insulated steam pipes

Sponsored Links

Heat loss from steam pipes depends on pipe sizes, insulation qualities, steam temperatures (steam pressures) and surrounding temperatures.

The table below and figure above can be used to estimate heat loss from bare un-insulated horizontal steam pipes - still air conditions - and air temperature ranging 10oC to 25oC.
