Thermodynamic Steam Trap

Steam systems require reliable condensate drainage to maintain heat-transfer efficiency, reduce steam loss and protect process equipment. African Valve, a Thermodynamic Steam Trap Supplier in Nigeria, supplies thermodynamic steam traps for automatic condensate removal from steam pipelines.

These compact mechanical traps operate using pressure and velocity differences between steam, condensate and flash steam. They are commonly used in steam distribution, process heating, steam tracing, boiler systems, refineries, chemical plants, power generation and industrial utilities.

Engineering Design & Operation

A thermodynamic steam trap consists mainly of a body, cover, disc, seat and internal control chamber.

When condensate enters the trap, pressure beneath the disc lifts it from the seat, allowing condensate to discharge. As hot condensate flashes into steam through the outlet, the resulting high-velocity flow and pressure changes cause the disc to close.

Steam pressure in the control chamber then holds the disc against the seat. As the steam above the disc gradually condenses due to heat loss, the pressure falls and the inlet pressure lifts the disc again.

This produces the characteristic intermittent cyclic discharge of a thermodynamic disc trap. Correct sizing and installation should consider differential pressure, back pressure, condensate load, piping arrangement and upstream straining.

Materials & Components

Other internal parts such as retainers, plugs, blowdown arrangements and check components can be supplied in stainless steel, carbon steel or application-specific alloys. Protective coatings may be provided for carbon-steel bodies where required by the operating environment.
