ASNT Level II Helium Leak

About ASNT Level II Helium Leak

Helium leak testing is a critical process in the engineering industry for ensuring the reliability and safety of vessels and valves that contain or transport pressurized gases or liquids. This testing method uses a small amount of helium gas as a tracer to detect leaks in the vessels and valves.

The process of helium leak testing involves several steps. First, the vessel or valve is evacuated to remove any gases or liquids that may be present. Then, helium gas is introduced into the vessel or valve, and the surrounding area is scanned with a helium detector. If a leak is present, the helium gas will escape from the vessel or valve and be detected by the detector.

Helium leak testing is a highly sensitive method that can detect leaks as small as 10 7 sacs (standard cubic centimeters per second).This level of sensitivity is critical in applications where even the smallest leaks can have serious consequences, such as in the transportation of toxic or explosive gases.

There are several benefits to using helium leak testing for vessels and valves. First, it is a non destructive testing method, meaning that the vessels and valves can be reused after testing. Second, it is a fast and accurate testing method, allowing engineers to quickly identify and address any leaks. Finally, it is a cost effective testing method, as it requires only a small amount of helium gas and minimal equipment.

In conclusion, helium leak testing is a critical process for ensuring the reliability and safety of vessels and valves in the engineering industry. Its sensitivity, accuracy, and cost effectiveness make it an essential testing method for applications where even the smallest leaks can have serious consequences.
