Insulated Steam Pipes - Condensate Generated
Heat loss from steam pipes generates condensate which must be drained from the system - imperial units.
Condensate load generated in insulated steam pipes at different steam pressures and piping dimensions:

The condensate load calculations are based on a surrounding temperature 70 oF and 80% efficient insulation. For temperatures at 0 oF the loads should be added approximately 50%.
