   en.wikipedia.org/wiki/Leak_detection

   The primary purpose of leak detection systems (LDS) is to help pipeline controllers to detect and localize leaks. LDS provide alarms and display other related data to the pipeline controllers to assist decision-making. Pipeline leak detection systems can also enhance productivity and system reliability thanks to reduced downtime and inspection ...

3. Hydrostatic test - Wikipedia

   en.wikipedia.org/wiki/Hydrostatic_test

   A leak will give a similar result to permanent set, but will be detectable by holding the volume in the pressurised vessel by closing the inlet valve for a period before depressurising, as the pressure will drop steadily during this period if there is a leak. In most cases a permanent set that exceeds the specified maximum will indicate failure.

4. Helium mass spectrometer - Wikipedia

   en.wikipedia.org/wiki/Helium_mass_spectrometer

   The vacuum chamber is connected to a vacuum pumping system and a leak detector. Once the vacuum has reached the mass spectrometer operating pressure, any helium leakage will be measured. This test method applies to a lot of components that will operate under pressure: airbag canisters, evaporators, condensers, high-voltage SF 6 filled switchgear.

5. Methane leak - Wikipedia

   en.wikipedia.org/wiki/Methane_leak

   A methane leak comes from an industrial facility or pipeline and means a significant natural gas leak: the term is used for a class of methane emissions. Satellite data enables the identification of super-emitter events that produce methane plumes. Over 1,000 methane leaks of this type were found worldwide in 2022. [1]
