Leak detection

Leak control using helium

The technique of helium tracing, a cutting-edge method, efficient, reliable and economical.
On piping for drinking water or any other liquid, this method allows us to carry out a quick inspection of the major pipes.On industrial pipework, it allows us to locate the smallest leaks.

Benefits

The helium tracing technique can be used with different pipes and is reliable and economical.

In comparison with traditional acoustic methods:

  • It can be used regardless of the type of pipe (metal or plastic) and its diameter.
  • Detection is possible on pipes that are in use or on empty pipes
  • Its effectiveness is not affected by ambient noise.
  • It is possible to detect 'silent' leaks.
  • The presence of helium in the ground necessarily points to the proximity of a leak; the size of the leak can be estimated depending on the levels of helium.
  • The Network Manager immediately knows whether it is a large leak that needs to be repaired urgently, a minor leak that can be dealt with in due course or just seepage.
  • The inspection is fast, with up to 4 km of pipes inspected per day.
  • No prior operation is required.
  • It is not necessary to cut the supply to the network or to clear out the surface boxes.
  • The helium tracing technique is very powerful and very reliable.

The technique is extremely sensitive and can detect leaks up to 0.01 litre/hour or 10 drops per minute.
