What is the steam leakage rate of a steam trap? Why is the steam leakage rate used to evaluate the performance of a steam trap?

The steam leakage rate of a steam trap is classified into two categories: under-load steam leakage rate and no-load steam leakage rate.

Steaming rate under load:

The steam leakage rate under load is defined as the percentage of steam leakage under load relative to the actual amount of hot condensate discharged during the test period.

No-load steam leakage rate:

The no-load steam leakage rate is defined as the percentage of the no-load steam leakage relative to the maximum hot condensate discharge at the corresponding pressure.

Since the primary function of a steam trap is to promptly discharge condensate from steam-heated equipment or steam piping systems while preventing steam leakage, thereby improving the efficiency of steam-using equipment and achieving energy savings, the key indicators for evaluating the performance of a steam trap should be its drainage performance and steam retention performance. Based on the definition of steam leakage rate, the magnitude of a steam trap’s steam leakage rate comprehensively reflects the quality of its drainage and steam retention performance.
