Helium leak testing is one of the oldest and most developed members of the family of trace-gas-based leak testing methods. Even though the title contains the word “helium,” this article is intended as an overview of trace gas methods in general.
According to the Compressed Air and Gas Institute (CAGI), the average compressed air system loses 30 percent of its air through leaks but locating those leaks has been a time-consuming and te-dious process.
Well-trained NDT technicians using the right combination of ultrasonic techniques can improve plant reliability and worker safety.

It’s been nine years since a heat exchanger burst at an oil refinery in Anacortes, WA, fatally injuring seven workers and bringing renewed attention to the risks of high-temperature hydrogen attack (HTHA).
Over the last 10 to 15 years, NDT methods have grown smarter and smarter. New methods have been developed and old methods have been improved. Some of today’s NDT is leaps and bounds ahead of where it used to be.
Nondestructive testing (NDT) is the most important industry you’ve never heard of. That’s how I typically start a STEM (science, technology, engineering, and math) demonstration.
Advancements in technology continue to enhance the capabilities of all areas of industrial quality and process control, and this is certainly the case within the various disciplines of nondestructive testing (NDT).
ASTM International’s additive manufacturing technologies committee (F42) is developing four standards that aim to help aircraft parts manufacturers meet safety and performance requirements.
