Helium Leak Testing

Ultra-sensitive helium mass spectrometer leak detection for critical sealing applications where conventional pressure tests are insufficient.

When Standard Tests Are Not Enough

Helium mass spectrometer leak testing provides detection sensitivity 1,000× better than conventional soap-bubble or pressure-drop tests. It is the method of choice for cryogenic equipment, subsea valves, nuclear components, and any application where even the smallest leak is unacceptable.

Applications

  • Safety valve bellows and pilot lines
  • Cryogenic valves and LNG equipment
  • Heat exchanger tube-to-tubesheet joints
  • Subsea valve assemblies
  • High-pressure gas system components
  • Vacuum system flanges and fittings
