Theory of Operation
        Steam traps improve the efficiency of steam systems.

        As steam travels through a piping system or is used in unit operations, it cools (condenses) into liquid condensate. A steam trap is simply a valve that automatically removes condensate and any other trapped gases such as air or carbon dioxide. When necessary, the steam trap Valves opens and releases the condensate and trapped gases and then closes to seal the steam system. Steam traps operate based on either density, temperature or pipe velocity.
    Advantages of Steam Traps
        Steam traps must be virtually maintenance-free.

        Depending on the application and details of the steam system, a steam trap can be expected to minimize costly steam losses and operate virtually trouble-free with minimal maintenance. Steam traps must also provide efficiency assistance to the heat exchange equipment they are associated with and have a lengthy service life before replacement. Some steam systems contain contaminants and are considered dirty. Steam traps must be reliable, even in dirty service, and must operate safely.
    Types of Steam Traps

        Over the years, most industrial steam traps have emerged in four types. Different applications dictate the choice of trap. An inverted bucket steam trap utilizes an upside-down bucket that floats when only steam is present. When condensate is present, the bucket sinks and opens the valve. A thermostatic steam trap monitors the temperature differences between steam and condensate. The float trap has a floating ball that operates the valve based on condensate level. Disc steam traps are small and operate on the velocity of fluid moving through them. As the impact of condensate enters the trap, it opens the valve to release the liquid.
