In this type of test, helium is used in finding smaller leaks or large leaks in bigger volumes. It is utilized as a tracer gas, and the concentration is measured. A helium leak test must be used for testing leaks since it is inert and is therefore safe to use. It will not react with any other material within the part that should be tested.
In the many tests conducted, a mass spectrometer is a device that is used. The importance of using it is that it can identify very small leakage as contrasted to using other tests as it only uses temperature independent dry method.
This type of test is very important when utilizing a vacuum system or even high pressure as it helps you to determine if a system is leak free. The leak detection unit creates a vacuum inside the product that you want to test. The fumes will then be sprayed on the outside. If helium is detected on the exterior of the system, you will be alerted with the detection unit. This enables you to determine the area of failure.
The two main techniques that can be used are pressure and vacuum testing. An appropriate detection method is decided by the products working state prior to testing. In vacuum testing technique, testing is done on the interior of the product. The device must be evacuated followed by spraying helium where you think there is a leakage. Gas detected after the experiment has been conducted shows that there is a leak. Repair should be done immediately.
In order for you to get quality results at all times, it is important you maintain the detection unit. Follow the manufacturers guidelines as far as maintenance is concerned. Annual services, as well as weekly and monthly inspections, should be done to determine if it is working correctly. Calibration of the unit should also be done frequently as it is an easy and straightforward process.
Gas is characterized by odor which a normal individual can easily notice at a concentration that is below an explosive range. Such a level of concentration ranges from zero points five to one percent. A gas odor indicates a leakage and information on this should be immediately investigated. When a leak is established, the movement of the fumes must be determined. If an accident exists, it must be eliminated immediately with the leak repaired.
Insects like flies, roaches spiders normally migrate to points of leaks because of microbial breakdown. Because some insects love the smell of gas, heavy insect activity near the regulator or meter can indicate a leakage. To confirm this, a test needs to be carried out.
A noticeable fungus-like growth near places such as the valve box indicates a leakage. This is due to the fact that fungi actively grows in areas that lack oxygen. Its color normally is white or greyish white. These indications must be investigated by use of a leak detection unit. In addition, all personnel should not climb down a manhole when the level of oxygen and gas concentration has not been tested.
