Saturated Steam: Every 150-300 feet (25-50 m) Superheated Steam: Every 300-500 feet (50-75 m) Steam Valve Station Drainage Install steam traps before normally closed manual valves, pressure reducing valves and control valves Armstrong International - Steam and Condensate Group armstronginternational.com Armstrong's Best Practices Piping Diagrams for Steam and Condensate Systems Steam Trap Location Points Steam Main Header Install condensate drain points with steam traps at the bottom of any vertical lift regardless of the steam flow direction. End of Steam Main/Header/Line Installation of air vents at end of main location will prevent air being trapped in steam header, especially during start-up periods. Broken or Improperly Spaced Piping Supports Steam Main Horizontal with Grade – No Slope Use downward slopes which are critical in keeping condensate lines clear—and also helps prevent corrosion and water hammer Pitch All steam distribution lines should be installed with a correct slope. Per ASME 31.1 and 31.3, lines that contain a steam/water mix, or require draining periodically, should be pitched downward approx. ½ inch per 10 foot in the direction of flow.
