Ultrasonic inspection of steam traps
Ultrasonic inspection is a non-destructive testing (NDT) technique used to detect anomalies in steam traps.
This method makes it possible to monitor the operating cycle of each trap and quickly identify blockages, leaks, or abnormal noises caused by water hammer.
By acting before these faults worsen, you improve the reliability of the steam network and optimize maintenance efficiency.
Monitoring of the operating cycle
In this spectrum, the visible peaks represent the ultrasonic signals emitted during the opening and closing cycles of the steam trap.
Analysis of the waveform makes it possible to immediately identify operating anomalies, such as a trap stuck in the open or closed position.
This visual monitoring facilitates diagnosis and helps plan targeted interventions before any issue affects the system.
Detection of faults before failure
In this photo, a deformed float can be seen, showing the typical marks of water hammer.
This type of overpressure can alter the shape and sealing of the float, causing steam leaks or improper operation of the trap.
Ultrasonic inspection makes it possible to detect these anomalies before failure, ensuring the safety and efficiency of your steam systems.

Anticipate to better protect
Ultrasonic analysis makes it possible to precisely monitor the operating cycle of each steam trap.
Each opening generates an ultrasonic peak visible on the spectrum, indicating blockages or anomalies in the cycle.
This early detection allows corrective action before a fault leads to energy losses or equipment damage.
Why perform this inspection?
As part of a predictive maintenance program, ultrasonic inspection is a strategic tool to:
-
Accurately identify traps with blockages or irregular cycles.
-
Reduce energy losses caused by faulty traps.
-
Prevent costly incidents and unplanned shutdowns.
-
Prioritize maintenance actions based on the severity of detected anomalies.
A non-destructive inspection with no downtime
The inspection is carried out without disassembly or production shutdown.
The ultrasonic sensor, positioned on the trap, records the characteristic sound emissions of its operating cycle.
This fast and safe measurement provides a reliable diagnosis under real operating conditions.
A detailed and actionable analysis report
Each inspection results in a comprehensive report including:
-
The location of defective traps.
-
A commented analysis of ultrasonic signals.
-
Targeted recommendations to guide your interventions.
This information facilitates planning of corrective actions, long-term monitoring, and optimization of steam system performance.
A strategic choice for your installations
Ultrasonic inspection of steam traps fits perfectly into a predictive maintenance approach.
Performing this inspection regularly helps secure your equipment, reduce energy losses, and extend the lifespan of your steam systems.
It is a predictive, effective, and sustainable approach that enhances both reliability and energy efficiency.
