Performance Graph
A graph titled 'Saturated Steam Curve' plots Temperature (°F) on the x-axis against Pressure (PSIG) on the y-axis. A curve indicates the maximum allowable working pressure for saturated steam at various temperatures, with a point marked '150 WSP'. The graph shows pressure increasing with temperature up to approximately 400°F at 400 PSIG, with a specific point noted at 150 WSP.
Note: The graph illustrates the relationship between temperature and pressure for saturated steam.
