A pipe designed to carry pressurized steam from a boiler to the working components, i.e. the steam engine's or turbine's. Such piping usually includes valves to control the routing of the steam, or to stop the flow altogether.
Area of Uses for Steam Piping :
Due to the high heat content of steam, relatively small bore, pipe work is required (to transfer certain quantity of heat load) to distribute the steam at high pressure.
Because of very high heat transfer properties of steam, the required heat transfer area is relatively small. This enables the use of more compact plant, which is easier to install and takes up less space in the plant.
