HELIUM LEAK TESTING
Helium leak testing is often used for gas tests with particularly stringent acceptance criteria due to the fact that helium has a far smaller molecular composition than nitrogen, which is more commonly used. In conjunction with the use of a mass spectrometer for sniffing purposes, this method has been proven to show that helium leak testing can be over one thousand times more sensitive in the detection of leakage paths compared to alternative metrics.
Tyne Pressure Testing has both the onsite equipment and extensive practical know-how in performing helium leak testing. This includes a range of different products bound for critical inline service for oil and gas production through to saturation diver watches. Assessment of the permeability of sealing barriers within these products has ranged from a matter of minutes through to several weeks of exposure in a helium-filled chamber.
