Steam traps discharging into a common header
Steam traps discharging into a common header
(OP)
I have several traps that are running in individual lines to a vented receiver tank. I would like to combine the discharge of the traps into a single line that goes into a new vented receiver tank.
The traps are all operating at varying upstream pressures..30psig, 175psig, 400psig, and 1250psig. I need some pointers on how to size the common line going to the new vented receiver.
I've found information on Sarco's website on how to account for flash steam in the condensate line from a single trap, but how do you account for several traps all operating at different pressures?
Thanks.

Don't put the discharge of the low pressure traps (30 psi), together with the 400 psi.

But how to account for that in the sizing of the condensate header?

Yes, I'm aware of steam induced waterhammer. That is partly why I asked the question. The other reason I asked is because flash steam in the condensate line after the trap can add significantly to required line size.
I believe there is a way to combine all the steam trap discharges into a single line, but I agree with the rest of you that the savings is not worth the risk of a trap failing. With a common condensate header, the operation of all the other traps would be affected by a failed high pressure trap.
Thanks for the input.
