Condensate drain pipe u trap calculation.

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. Listed internal static return external static total static at drain 2. Condensate line could freeze.
