Non-destructive testing "Helium leak test" [Problem solving]

Detecting a tiny leak through which helium gas with a molecular weight of 2 is permeating!

Helium leak testing is one of the non-destructive inspections that is considered important not only in Japan but also in various countries around the world, including Europe and the United States. It is widely conducted in various fields such as chemical plants, nuclear power, and space development, and engineers need to have sufficient knowledge and experience regarding the characteristics of vacuum and leakage. There are various inspection methods tailored to specific purposes, such as quantifying the amount of leakage by pressurizing the inside of a product with vacuum or helium gas, and identifying leak points from invisible cracks. [Customer's Issue] There has been a phenomenon where the building's air conditioning (absorption chiller) does not heat or cool properly, necessitating urgent action from the supplier. [Solution] Conduct a leak test after vacuuming the piping system using helium leak testing to identify the leak points. The manufacturer will repair the identified areas, and a re-inspection will be carried out to confirm that there are no leaks. *For more details, please contact us or refer to the PDF.
