Leak detection on process plant or systems using a helium trace in a nitrogen carrier gas, is the most accurate and quantify-able method available. On an offshore production platform module, or within a petrochemical complex, the elimination of hydrocarbon leakage is an operational priority. Such loss of containment can lead to hazardous situations, environmental impact and financial loss.


What is Helium Leak Testing:

Helium is used to find small leaks or possibly larger leaks in bigger volumes. The helium is also used as a tracer gas and its concentration is measured


Nitrogen/Helium Leak Testing :

  • Gas booster and N2 bottles for testing of process and piping systems with low volume and pressure
  • Nitrogen pump and LN2 tank for testing of larger volume/ higher pressure process and piping systems
  • Remote and portable leak detectors (mass spectrometer)
  • Ultrasonic integrity test to process and piping system valves
  • Silencer fitted during bleed-off

Scope of use :

  • Purging during shut down and maintenance programmers
  • Leak testing of new process plant and system
  • Leak testing following system shut down, maintenance or modification
  • Test run and start up of compressors ‘live simulation’
  • Commissioning of pipelines
