Thermal insulation solutions for piping and equipment operating at cyclic temperatures.
Thermal insulation solutions for piping and equipment operating at cyclic temperatures.
Systems that are in dual temperature service operate at temperatures varying between two limits, usually a high temperature and a low temperature.
In this case, the limitation of the surface condensation applies for the low temperature and the limitation of the surface temperature for the high temperature.
The heat transfer limitation for economic reasons applies in both cases, in function of the time periods during which the installation is running at the given temperatures.
The process control requirement and the eventual fire protection requirement are often less stringent, although they can become predominant in some particular cases, depending on the product that runs through the pipes.
