What is the purpose of a steam trap?

The primary function of a steam trap is to discharge condensation and non-condensables from a steam system. Steam traps are essential components in various industrial applications involving steam, serving to segregate steam from water or other impurities that can accumulate in the system. When steam is introduced into a system, it condenses into water as it loses heat. If this condensation is allowed to remain, it can lead to inefficiencies, potential damage to equipment, or even complete system failure.

By removing these condensates and non-condensable gases, steam traps help maintain optimal performance, ensure efficient heating, and prevent water hammer, which can cause damage to pipes and other components of the system. Therefore, the correct answer highlights the steam trap's crucial role in maintaining the integrity and efficiency of steam systems, ensuring that steam can continue to flow without obstruction from condensate.
