CORE SERVICE OFFERINGS

Helium Leak Test

The Helium Leak Testing unit at TCR Arabia utilizes a proven mechanical vacuum pump technology designed specifically for heavy usage under harsh industrial environments. The helium stability of the rotary vane pump guarantees excellent stability of the helium signal.


TCR Arabia's services include vacuum leak testing for any type of vacuum vessel as well as system and pressure probe testing for systems that normally operate at or above ambient pressure. Virtually any system that has a requirement for leak tightness or that is suspected of causing a problem due to leakage can be tested by one of these methods of helium leak testing with a high degree of reliability.
 

The low rotational speed of the M.D.P. (Molecular Drag Pump) at 27,000 RPM keeps this unit completely insulated against accidental air inrushes. Further, it allows the leak detector to be moved while in operation. The high compression ratio of the M.D.P. facilitates the gross leak test at a high pressure (7.5 Torr / 10mbar) which speeds up the leak test process of outgassing parts. The internal layout of the unit allows easy access to all the components. 

 

TCR Arabia’s Helium Leak Testing instrument has a roughing capacity of 10 m³/h (7 CFM) with usable helium sensitivity in the 10-11 atm.cc/s range. The unit has a dedicated sniffing unit, based on a well-proven leak-testing concept and is available for outboard leak testing applications as well.

Additionally, the unit offers evolved features to assist the operator with daily test operation:

  • Auto-calibration, with built-in temperature, compensated calibrated leak (dedicated to the sniffing mode) 

  • Automatic signal correction 

  • Vocal synthesizer

  • Helium background suppression with "floating" zero to keep the signal from going negative and to increase sensitivity

  • Audio alarm with variable pitch (up to 90 dBA) 

TCR Arabia has performed several leak tests on-site for industries that include nuclear carriers, polymer plants, oil refineries, gas and steam turbine power plants in Kuwait, Kingdom of Saudi Arabia and India. TCR's technicians are highly mobile and perform helium leak testing on heat exchangers, steam turbines and condensers, distillation towers, buried pipelines and many other systems and components.

Why Helium Leak Test?  

  • Product Life

  • Reliability

  • Avoid unexpected shutdown


Why Helium is a good tracer gas?

  • Low concentration in air, only 5 ppm, so low natural background

  • Helium being an Inert gas is non-toxic, non- explosive and environmentally friendly

  • Good separation in a mass spectrometer (no cross-sensitivity to other gases and no mass fragments

  • Lighter than air

  • Very small gas molecule, can easily pass through small holes/gaps
