7 Energy efficiency tips for steam trap monitoring and maintenance


  1. Remove Dirt

Dirt is one of the most common problem areas. Dirt, scale, or foreign material finds its way to the traps and often damages the valve seat, preventing it from closing properly and leading to leakages.

  1. Upstream strainers

Strainers provided for handling dirt and other material before it reaches the traps must be maintained properly.

  1. Install sight glasses

Sight glasses, fitted after the traps, permit visual identification of blowing traps and need to be properly taken care of.

  1. Proper trap selection

If the trap selected is not the appropriate type and size for the given application, significant losses take place.

  1. Visual check according to the type
  • Inverted bucket and thermodynamic traps should have intermittent condensate discharge.
  • Float and thermostatic traps should have a continuous condensate discharge.


  1. Detect steam leakage

Flash steam and leaking steam are not the same. Leaking steam is continuous, like an exhaust, while flash steam is intermittent and like a cloud.


  1. Ultrasonic and thermal testing

Mechanisms within the traps produce sonic and ultrasonic sounds due to passage of condensate and steam. Using suitable listening devices, ranging from a simple screwdriver, a mechanic’s stethoscope, or an ultrasonic trap tester, a trap monitoring system can be established in an industry.

Similarly, temperature sensing by contact and non-contact devices can help to monitor trap performance.
