Steam traps are used to remove condensate from a process steam system or heat exchanger with a minimal loss of steam energy.In mechanical steam traps the free float rises with condensate flow,opening the valve to drain the condense,when steam enters,it falls and closes the valve.In thermodynamic steam traps the pressure and temperature drop caused by condensate entering the trap opens the valve disc to discharge condensate,the valve results for this questionIs there a steam trap off the steam main?Is there a steam trap off the steam main?In the photo to the right,there is a steam trap off the steam main,and condensate is returned to the to the top of the condensate pipe.However,the steam trap is piped off the TOP of the Steam Main.Because condensate is on the bottom of the pipe,this trap is doing nothing to help keep the line dry.Steam Piping Best Practices CleanBoiler

A level connects the ball float to the valve and seat.Once condensate reaches a certain level in the trap,the float rises,opening the orifice and draining condensate.A water seal formed by the condensate prevents live steam loss.Since the discharge valve is under water,it is not capable of venting air and non-condensables.How It Works Steam Traps SchlumbergerThe American National Standards Institute defines a steam trap as a selfcontained valve that automatically drains the condensate from a steamcontaining enclosure while remaining tight to live steam,or if necessary,allowing steam to flow at a controlled or adjusted rate.Most steam traps will also pass noncondensable gases while remaining tight to live steam.
