Steam Tracing with MS Excel

May 24 2012 06:50 PM | adelange in Heat Transfer

Heat tracing is used to prevent heat loss from process fluids being transported in process fluid pipes, when there is risk of damage to piping, or interference with operation such as fouling or blockage, caused by the congealing, increase in viscosity, or separation of components, in the fluid below certain temperatures, or when there is risk of formation of corrosive substances or water due to condensation in corrosive services.
