KNOWLEDGE & INSIGHTS

Leak testing entails verifying whether a component is properly sealed or pinpointing the location of a leak. A leak is usually an unintended crack, hole, or porous area in a wall or joint designed to contain or block fluids and gases, allowing the enclosed substance to escape.

​Such a leak causes fluids to unintentionally flow through the walls of a vessel or sealed container, driven by a pressure difference between the inside and the outside. This causes air to move from high-pressure zones to low-pressure zones.​

Poor industrial leak testing carries significant risks and financial consequences, including compromised safety, exposure to hazardous substances, regulatory non-compliance, operational disruptions, and additional costs from product recalls or legal liability.

So, how is leak testing done?

To perform leak testing, a set pressure or vacuum is applied to the test part. Various techniques are then used to detect, measure, and locate any leaks. The goal of leak testing is to give manufacturers confidence that their products meet required leak-tight specifications, ensuring safe and reliable operation.

There are different test methods, including Air-based testing (Micro-Flow, Mass Extraction), Tracer gas methods (helium, hydrogen), Residual gas analysis (RGA), and Optical emission spectroscopy (OES). Some cutting-edge industrial leak-testing machines combine multiple testing methods, providing greater flexibility.
