Helium Leak Testing

Helium Leak Testing

Electro Chemical provides comprehensive helium leak testing services to improve the life cycle and quality of fluoropolymer coatings and linings.

What is helium leak testing?

Helium leak testing is used to find very small leaks in fluoropolymer lined vessels where traditional dielectric spark testing is inconclusive. The helium is used as a tracer gas and its concentration is measured.

Why use helium for leak testing?

Helium is one of the smallest gas molecules and is inert. Helium is used as a tracer gas because it penetrates small leaks rapidly, and the leak can be isolated and pinpointed so that an immediate repair can be made.

What are the benefits of Helium Leak Testing?

Using this technique you can test to find smaller leaks than with traditional testing processes such as dielectric spark testing. The end result is a higher quality system and a longer product life cycle.

Mass Spectrometer Leak detection with Helium charged – Sniffer Test

Sniffing is used where the part can be pressurized above atmospheric pressure and a sniffing gun is manually positioned around the vessel for testing. The mass spectrometer is fitted with a special device, a sniffer probe, which allows it to sample air and helium tracer gas when confronted with a leak.

Helium leak testing is frequently used to locate a leak that has been undetected by other traditional methods.
