Condensate Lines
Condensate Lines
(OP)
I have a question about line list conditions for condensate lines. Say that there is a 50# saturated steam line, and steam trap, and then a condensate line that is feeding into an open sewer. I have seen two types of conditions listed for the condensate line. One way shows the condensate line with normal operating conditions of 0 psig at 212 F. The other method uses the normal operating conditions of the saturated steam line, 50 psig at 298 F. Which of these conditions would be the correct ones to use? Thanks for the help!

The pressure is really immaterial since both lines will be class 150 piping (at least in my field, we never use anything less than class 150 for condensate). The only difference between using 212F and 298F is the amount of flexibility allowed in the piping design. It's not an issue if the trap discharges obviously into a hub but if you run a few hundred feet, it can affect how much growth is allowed.
