Note: Heating a steel steam trap for calibration testing

Objective:

To heat a steel steam trap to 212 °F (100 °C) to release steam for calibration testing 

End Product:

Steam trap

Equipment:

Ambrell 2 kW induction heating system, equipped with a remote workhead containing two 0.33 μF capacitors for a total of 0.66 μF
An induction heating coil designed and developed specifically for this application

Materials:

1.4 in (35 mm) OD, 0.3 in (7 mm) thick steel disc that has water inside 

Temperature:

212 °F (100 °C)

Frequency:

293 kHz

Testing:

A four-turn pancake coil is used to heat the bottom of the steel steam trap to 212 °F (100 °C). After 10 seconds the water inside will reach 212 °F (100 °C) and a ball bearing will release steam created from the water inside and allow for calibration testing. 

Benefits:

  • Repeatability and consistency

  • Even distribution of heating

  • A faster process time, saving time and energy
