Steam Trap Sizing Guidelines

Steam has many uses, including applications in the industrial industry.

Industrial production for a variety of materials often includes the constant use of steam. The controlled steam powers industrial machines, but requires a secure way of regulating its release, through steam traps.

Function

Steam traps are valves that can allow steam to be released from a tank to relieve pressure or heat. In addition, the valve can close to contain the steam and keep the heat and pressure constant.

Size

Each system is unique and requires careful consideration before choosing a steam trap size. Variables that necessitate calculation are how much total pressure load the tank will need to withstand, as well as the input and output pressure levels at the steam trap's attachment.

Considerations

Of the four steam trap types available, including thermostatic, thermodisc, float and thermostat (F&T), and inverted bucket, each has their own advantages and disadvantages. For overall safety, the steam trap chosen should have a pressure capacity higher than the maximum calculated for the system.
