I would like to ask what technologies are currently used for leak detection in pressure vessels

The cost of helium testing is relatively high. It seems there is now a method called hydrogen leak detection; I’m not sure if anyone has heard of it: http://www.cjkj88.com/
Helium mass spectrometers have a similar effectiveness to hydrogen leak detectors, but their cost is lower than that of helium mass spectrometers
Hydrogen leak detection – what about safety? ~~
5% hydrogen + 95% nitrogen is safe enough in this ratio
For Gree and Midea air conditioners, helium mass spectrometers were previously used for leak detection, but now hydrogen leak detectors are used in all cases – they are cheaper, as helium is expensive; the accuracy of both methods is more or less the same
It’s the hydrogen-nitrogen mixture leak detection method~~ Indeed, the cost of hydrogen is lower than that of helium, and hydrogen has strong permeability, which is advantageous for leak detection~~
I checked out your link~~ Indeed, this method has certain advantages and is advanced~~ It’s possible that it could eventually replace helium leak detection to some extent~~
Yes, this method actually originated abroad and is being used by many well-known companies; currently, only a few companies in China are using it
As long as the advantage is significant, the application will develop rapidly~~
