Steam Trap Sizing
Proper steam trap sizing is a critical factor in obtaining efficient and reliable steam trap operation. Incorrect steam trap sizing can negate proper trap design, installation, and can cause condensate backup, steam loss or both.
Steam trap sizing is sometimes mistaken for selection of the steam trap connection size. Rather it is the proper sizing of the internal discharge orifice. (For low pressure steam heating systems, manufacturers produce steam traps with connection sizes that relate directly to capacity, orifice size). However, an industrial steam trap must be sized by selecting the proper discharge orifice. A two-inch steam trap can have the same condensate capacity as a steam trap with a half-inch connection. Once the condensate capacity is determined and the proper orifice size is calculated, the steam trap connection size can then be determined to meet the installation requirements.
