Standard Leak Test Machines and Bespoke Solutions
TQC specialise in automatic leak testing of components using water submersal, air decay, vacuum or hydrogen/helium tracer gas methods. We can provide standard leak test machines and bespoke solutions.
The test method used depends on the application and the leak rate that is acceptable and whether any leak locations need to be determined. These principles are outlined in the Basic Principles Page.
Pressure/Vacuum – TQC have experience of supplying a range of leak measurement instruments from different suppliers. Test pressures between vacuum and 16bar (150psig) are available as standard. Leak measurement may be made down to a resolution of 1 atm.mm3/sec. All test parameters are programmed into the instruments and the result data is available for subsequent SPC analysis.
Pressure decay machines are: the lowest cost solution, simple to understand, give direct value results, offer direct calibration, temperature dependent, and require that the component must be stable.
Helium Systems – TQC provide complete test facilities utilising leak test instruments and pumping groups from leading global suppliers. Helium leak testing is generally used for specifications which are too stringent for pressure decay or where the component is large in volume or not stable in shape or temperature. The leak measurement resolution may be typically 1 x 10-6 atm.mm3/sec.
Helium detection machines are: the most sensitive (typically 1 x 10-6, 1 x 10-10 is possible), are independent of temperature, are independent of volume, offer high throughput, are the most expensive solution, and are often the
