What is the function of a steam trap?

Steam traps are automatic devices that remove condensate (water) that forms in steam lines while letting the live steam continue to flow. As steam releases its heat, it condenses back into water and must be drained from the system without letting steam escape. The trap senses the presence of condensate (usually by differences in density, temperature, or pressure) and opens to discharge it, then closes to prevent steam loss. This keeps heat transfer efficient and helps avoid issues like water hammer. That’s why the best description is removing condensate from steam lines while preventing steam loss. The other ideas—removing dirt, filtering steam, or stopping steam flow—aren’t the function of a steam trap and are handled by other components (strainers/filters, or control valves).
