Condensate Drain Pipe U Trap Calculation

For most drain points sizing the trap to pass twice the running load at the working pressure minus any backpressure will allow it to cope with the start up load.

For steam mains drainage the condensate load for each drain trap is typically 1 of the steam capacity of the main based on drain points at 50 m intervals and with good insulation. Minimum sea level with fan on fan outlet pressure recommendation. Trap for blow thru unit fan running and condensate beginning to drain away.
