Yearly Heat Loss from Steam Pipes
Yearly heat loss from steam pipes can be considerable. This table compare the yearly heat loss in the amount of coal and oil consumption for insulated and uninsulated steam pipe lines at different dimensions and operation time.

The yearly loss is estimated for pipes with a steam pressure of 6.5 bar and surrounding air temperature of 20oC. Increasing the steam pressure will increase the temperature and influence on the energy consumption and heat loss.
