Nitrogen Helium Leak Detection Commissioning Leak Testing (CLT) is to confirm integrity of system where water may not be used and has been improved and refined continuously. CLT is achieved by pressurizing process system or component to be tested to their design pressure with a test medium comprising of 99% Nitrogen and 1% Helium.
High Sensitivity Helium Leak Detection (HSHLD ®) was developed by ORS to simultaneously measure Helium and Oxygen to determine Fine and Gross leaks in one simplified test.The HSHLD ® method is a dry method that is sensitive to 10-12 atm cc/sec with cycle times less than 2 minutes and can measure devices with internal free volumes as small as 0.005cc.
Helium hermeticity testing is used to verify the seal process of a hermetic device. Devices are typically preconditioned in a pressurized chamber and, after the required conditions are met, the leak rate is measured and recorded, applying pass/fail criteria.
The flooding of the leak test instrument with helium may take several minutes for the helium to reduce to a level where testing can recommence. To reduce the effect of a large leaker one can; build up to the full test pressure in stages, build up to the full concentration, flush the mass spec with a gas with no helium present or pre-screen ...

Nitrogen Purging and Leak Testing. We provide a range of nitrogen services including nitrogen purging and nitrogen/helium (N2/He) leak testing to production installations and pipelines offshore and to petrochemical, LNG, refining, power generation and process plants onshore.
Helium leak testing is a non destructive examination method which is used for detection and localization of leaks by measuring leakage in systems or objects under vacuum or pressure. In Helium leak testing a pressure difference is produced between the outer and the inner side of the object to be examined.
Helium Leak Testing Services. Helium Leak Testing Detect the Smallest of Leaks . The helium leak testing takes advantage of the relatively small size of the helium atom as the indicating gas for detecting the smallest of leaks. Therefore, it is a valuable test in searching for leaks in brazed assemblies.
Helium is the best choice of tracer gas to find leaks for a number of reasons. It is non-toxic, inert, non-condensable, non-flammable and not normally present in the atmosphere at more than trace amounts (5 ppm). Due to its small atomic size, helium passes easily through leaks. The only molecule smaller than Helium …
Helium leak testing is the most reliable and conclusive method of leak detection, in comparison with bubble testing which is suitable for identifying only large leaks and cannot quantify them. At Intero Integrity Services, we offer flexible solutions which can be adapted to our client's needs.

A low-cost alternative to helium is forming gas, typically a mixture of 5% hydrogen and 95% nitrogen that can be used as a safe, non-flammable, and effective tracer gas in many applications. A mass spectrometer gas analyzer can be used in tracer gas leak testing to detect helium or hydrogen escaping from a micro-leak.
IRC AdvancedNDT Services have started offering Helium Leak Testing services with the latest state-of-the-art technique Alcatel ASM 142 helium leak Testing Equipment, the most widely used means of leak testing.

Helium leak testing is required for all of the cryogenic equipment and vacuum vessels we build. Final leak tests are performed once the vessel fabrication is complete. There are also numerous intermediate leak checks performed on subassembly weldments during different stages of the production process.
Helium Spray Leak Detection: Is a two-phase gas leak testing process where parts are first placed in a vacuum sealed vessel to perform initial leak detection. If it passes the first phase, helium is then applied to the part to sense whether there are any gas leaks.
