Steam Trap Types - Steam Specialty
BASICS OFSTEAMTRAPSWHY DO WE NEED Steam TRAPS?In order to operate economically andefficiently, all Steam systems must beprotected against 3 factors:* CONDENSATE* AIR* NON-CONDENSIBLESC ondensateis formed in a systemwhenever Steam gives up its useableheat. And, since condensate interfereswith the efficiency of the operation of asteam system, it must be , one of natures finest insulators,when mixed with Steam , will lower itstemperature and hinder the the overalleffectiveness of an entire system. Forexample: A film of air 1/1000th of aninch thick offers as much resistance toheat transfer as 13" of copper or 3 ofsteel. For that reason, air MUST becontinuously bled from a system bysteam traps to have it operateefficiently and to conserve , such as carbondioxide promote corrosion and otherdeterioration of equipment and inhibittheir IS A Steam TRAP?
contacts the bimetallic discs, the discs relax. Inlet pressure forces the valve away from its seat and permits flow. Figure 17: When steam enters the trap and heats the bimetallic discs, the discs expand forcing the valve against its seat preventing flow. Bimetallic traps are simple and positive in both directions. However, they have
