N2He Integrity Leak Test
Involves pressurizing the system with a combination of nitrogen and helium gases, followed by the utilization of specialized equipment to identify any gas leakage and precisely locate the source of leaks. Nitrogen creates a safe testing environment by displacing oxygen, while helium is highly sensitive in detecting leaks due to its small molecular size.
The use of nitrogen and helium in combination provides a comprehensive approach to leak detection, addressing both safety and accuracy requirements.
