<h2 class = 'uawtitle'>How To Conduct A Helium Leak Test</h2><br />

<div class='uawarticle'>Helium is the major gas mostly utilized in this kind of experiment to sense both big and tiny seepage in larger volumes. It is used in this test as a tracer gas where its intensity is measured. A <a href="https://www.reliantvalve.com/Services">helium leak test</a> should be considered when you want to test seepage since it is inert and secure for users. It also will not react with materials during testing.<br />
<br />
In a majority of the tests, a mass spectrometer is used. The main benefit of using this gas is that you can be able to find small leaks as compared to other tests by using a temperature independent dry technique. When you are suspecting that there is a leakage in the company system, consider using this type of technique.<br />
<br />
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.<br />
<br />
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.<br />
<br />
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.<br />
<br />
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.<br />
<br />
Insects including spiders, cockroaches, and flies like living in points of leakages because of the microbial breakdown that exists around such an area. As they are interested in the smell of fumes, insect activity around the regulator or meter may indicate leakage. To confirm this, an experiment ought to be conducted.<br />
<br />
A fungus-like growth around places like the valve box can indicate a leak. This is because fungi grow where there is no oxygen. The color of growth can be greyish white or white. All these indications need to be investigated using a leakage detection instrument. Workers should not enter manholes without testing the level of oxygen and fumes concentration first.<br />
