Our leak testing methods

Our core competence, leak testing with a trace gas such as helium, is a reliable method for detecting leaks in industrial applications. Thanks to the small molecular size of the trace gas, even the smallest leaks can be precisely identified.

Helium vacuum leak testing

In the helium-vacuum method, a test object is placed in a vacuum test chamber. Then, the chamber and the test object are evacuated. Once the target vacuum has been reached, helium is introduced into the test object at test pressure while a mass spectrometer detects the helium concentration in the chamber. An increase in this concentration indicates a leak in the test object. This method is used in industries with high leak tightness requirements due to its high sensitivity and accuracy.

Helium sniffing method

In the helium sniffing method, the test object is pressurized above atmospheric pressure. This is done with helium, a helium mixture or forming gas. The escaping tracer gas at potential leaks is then detected from the outside using a “sniffer” probe connected to a mass spectrometer by passing it over the surface of the object. An increase in the helium concentration at the detector indicates a leak. This method is particularly suitable for pinpointing leaks.

Ultrasonic leak testing

In the ultrasonic gas bubble detection method, the object to be tested is immersed in a water bath and pressurized. If it is leaking, gas bubbles escape from the object. This technique is reminiscent of the classic patching of bicycle inner tubes, where leaks are made visible by air bubbles rising in the water. In an industrial context, ultrasound is used to detect and precisely localize the escaping gas bubbles.

From practice

MACEAS checks the tanks of Europe’s first bio-LNG ferry "FS Richmond" for leaks

The ferry “FS Richmond” from Stadtwerke Konstanz GmbH, which operates on Lake Constance, is a first in Europe: It is the first of its kind to run on high-speed gas engines and be powered by organic LNG in an environmentally friendly way.

As part of the commissioning process, the MACEAS team was contracted to check the vacuum-insulated tanks for liquid gas on board for leaks.
