Leak Detection
Overpressure and underpressure

To detect leaks as soon as possible and to prevent contamination, the use of double-walled tanks and piping has been made mandatory in most countries across Europe. All of our leak detection systems work on the pneumatic principle - overpressure or under pressure (or pressure/vacuum). Air or gas is applied to the interstitial space (gap between the inner and outer wall) and monitored with a leak detector. If there is a leak, the pressure in the interstitial space drops and an alarm is triggered. There are only a few leak detection specialists and TSG work with the best: SGB. SGB provides a full range of overpressure and under pressure leak detection technologies for double-walled tanks and pipes.
