Ultrasound

Ultrasound is high frequency sound waves above 20 kilohertz (kHz) up to 300 kHz. As a comparison, the average human’s perception falls around 16 kHz. Commonly used for leak detection and mechanical and electrical inspections, Ultrasound is one of the more flexible CBM technologies on the market and can be an important tool to deploy in your journey to Reliability Excellence and Maintenance Excellence.

Why?

Although Ultrasound testing provides many benefits, there are two primary areas that generate the greatest value to a plant:  air leak detection  and electrical applications. For electrical applications, safety is always a concern. Ultrasound can be used as a safety precaution for identifying failure modes such as Arcing, Tracking and Corona. The more common failure modes that Ultrasound detects:

  • Compressed gas leaks
  • Heat exchangers
  • Boilers and condensers
  • Tanks and pipes
  • Valves and steam traps
  • Arcing, tracking, corona
  • Switchgear
  • Transformers
  • Bearing faults
  • Gear problems
  • Circuit breakers
  • Coupling defects
