condensate temperature
(OP)
Hi
I am designing a condensate pipeline. I have a problem how to determine condensate temperature.
The condensate pipeline is about 110 m long. Dividied in to two section in a building and outside. The pressure before steam traps is 6 bar. Behind the steam traps I lift the pipeline by 5 m. Then with a constant fall
to a tank with atmospheric pressure.
The outdoor section will be run in preinsulated pipes of max. working temperature 140C. I wonder if it's enough.

RE: condensate temperature
IMO, the condensate should be cooled down as soon as possible and to keep the tank temperature below boiling. And, the pipe can be insulated for the personal protection only.

RE: condensate temperature
friction loss 0,4 bar
all togheter about 1 bar loss
So for 1 barg I have temperature 120C.

Some design codes require drain (condensate) lines to be designed for the upstream conditions

Don't forget the pressure drop on the steam traps.
Isometric sketch possible?
