Helium Pinpoints Leaks

Helium is the lightest inert gas.  Introducing helium as part of a leak detection process is very effective because this light inert gas will escape from any leaks in the piping or vessel quickly.   Thus, helium will penetrate the surface easily.  In fact, helium diffuses through solids at three times the rate of air.  Helium gas is also ideal because it will not react with other elements making it safe to mix with hydrocarbon vapors.

Detecting leaks with helium is ideal because:

  • Helium diffuses through solid cracks faster than any other element
  • Helium detectors provide a quantitative measurement which makes it easy to determine leak sizes and severity of the leak.

What types of systems do we test?

This testing process is effective on any size or type of piping or vessels including:

  • underground storage tank systems
  • above ground storage tank systems
  • floating roof systems
  • oxygen systems
  • hydraulic lines
  • oxygen systems
  • fuel lines
  • pressurized cables
  • gasoline service stations
  • heat exchange chambers on furnace

The helium leak testing works on any system that can be sealed and pressurized.

Helium Detection Process for easily accessible systems

  • A vacuum decreases the pressure inside the vessel.
  • A detector is attached to the evacuated area.
  • Helium is sprayed around the outside to identify leaks.

Helium Testing Procedure for buried lines, underground tanks & heat exchange chambers

  • Introduce helium inside the vessel.
  • The helium enters the area & increases pressure on the system.
  • A detector is used around the outside to detect any gas that might escape.
