Introduction to Contracted Services for Helium Leak Testing in Air Tightness Testing

[Leak Test] Pressure vessels, vacuum chambers, piping units, etc., can detect minute leaks and identify defective (leak) locations!

The airtightness test "Helium Leak Test" 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. There are various testing methods depending on the purpose, such as quantifying the amount of leakage by pressurizing the product with vacuum or helium gas, and identifying leak points from invisible cracks. Ultimately, this also helps prevent leakage accidents. In this article, we will introduce the challenges faced by our customers and the solutions. ■Challenges Due to phenomena such as the building's air conditioning (absorption chiller) not heating or cooling properly, urgent action is required from the supplying manufacturer. ■Solutions We conducted a leak test after vacuuming the piping using the airtightness test "Helium Leak Test" to identify the leak points. The manufacturer repaired the identified areas, and we conducted a re-inspection of the repaired areas to confirm that there were no leaks. *For more details, please contact us or refer to the PDF.
