Steam Pipe Diagram. Riser diagram electrical general notes. Steam lines should ideally be arranged to fall in the direction of flow at not less than 100 mm per 10 m of pipe 1100this slope will ensure that gravity and the flow of steam will assist in moving the condensate towards drain points so that the condensate may be safely and effectively removed see fig.
Steam supply lines need to be drained of condensate. This ensures that high quality steam enters the coil. On start up of the system the condensing rate will be at its maximum as this is the time where.
Condensate return piping should be the same size as the coils return connection from the coil outlet to the steam trap.
See note 1 in figure 3 steam coil piping diagram on page 3. Designs where one steam trap is used for multiple condensate drainage are to be avoided. The system is simple but the heat emission from radiators or in heat exchangers is hard to control. Steam on contact with the cooler pipes will begin to condense immediately.
