Piping Installation 1: Waste Steam Inlet Piping
no condensate
accumulation points (places where piping rises or falls)
feed water tank or other
“non
pressure vessel
”, do not install
valves, check valves, etc. on the
steam piping.
Other cautions
The piping diameter should be sized so that the flow velocity of steam is
approximately 20 m/sec (66 ft/sec).
To handle steam without applying back pressure on steam-using equipment, it is
recommended that the piping be of the same diameter as the SR steam inlet (SR-3:
80 mm (3 in), SR-8: 150 mm (6 in)). Suggested diameters for the steam inlet piping
are as follows:
