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 testing methods 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 vacuum and leakage characteristics. There are various testing 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 leakage 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 supplying manufacturer. 【Solution】 Conduct a helium leak test to perform a leak inspection after vacuuming the piping system and identify the leakage points. The manufacturer will repair the identified areas, and a re-inspection will be conducted to confirm that there are no leaks. *For more details, please contact us or refer to the PDF.
