Drainage equipment, transmission lines, and tanks under steam and gas pressure in the oil and gas industry, power plants, food, and other industries.

Vent silencers are used to control the noise produced by air or gas released from a high-pressure line to the ambient environment. This sudden discharge causes noise. For example, in safety valves, if the pressure exceeds the allowable limit, then the gas is discharged to the environment to reach the desired pressure. The amount of sound produced mainly depends on the pipeline pressure and the diameter of the outlet pipe.
