Abstract: The high-temperature and high-pressure steam generates high-decibel noise during the discharge process of the steam trap, which has a great impact on the working environment of the entire plant area. This is not conducive to the workers’ peace of mind and easy to cause safety accidents. This paper introduces the noise reduction processing device and precautions for the high-decibel noise generated by the hightemperature and high-pressure steam through the steam trap. The noise is processed by the phase change method, the small-hole frequency conversion method and the multi-level diffusion method to deal with the noise. Thus the noise during emission is reduced sharply, which basically meets the needs of the working environment.
