Steam Trap Surveys Many energy conservation programs start with a steam trap survey because leaking traps can raise a company's overhead operating expenses by as much as a third. Energy audits and repairs often save companies hundreds of thousands of dollars.
Ultrasonic testing can quickly reveal the condition of each steam trap.
In fact, the major trap manufacturers recommend regular testing. A contact probe used to localize the sound coming from the trap will not pick up the other pipe noises since ultrasound intensity falls off rapidly as it moves away from its source. Continuous-flow traps usually modulate according to condensate load and a failure most often occurs in the closed position. A failure usually occurs in the open position causing a constant rushing sound. Each trap in this category has its own particular method of operation and pattern of open-close.
