In this test, helium is normally used in detecting small leaks or big leakage in bigger volumes. It is normally used as a tracer gas whereas the concentration is measured. Helium leak test is useful in testing leaks as it is inert hence very safe for usage. In addition, it does not react with other materials within the part awaiting testing.
In a majority of the experiments done, a specialized device known as the mass spectrometer is required. One main advantage you will get by utilizing helium is that it will identify very small leaks when compared to other experiments. It uses a temperature independent dry procedure.
This test is very crucial more so when you are using high pressure or vacuum system since it assists you in concluding whether there is a leakage in the system. A leak detection unit is able to create a vacuum in the interior of a product you want to be tested. It is then sprayed on the exterior. If there is the detection of helium on the exterior, the detection unit will immediately alert you. You, therefore, will be able to know the exact area of failure.
The two important methods for testing are a vacuum and pressure testing. The most suitable leakage detection technique is dictated by the working state of the product to be tested. For vacuum testing method, a product is tested from the interior. The device should be evacuated, and then the gas needs to be sprayed where there is a leakage. Any helium that may be detected in the device when the test has been done indicates a leak, and therefore repair must be realized.
To ensure that you are offered results one can depend on, the leakage detection unit has to be cared for. You need to follow the guidelines provided by your manufacturer on maintenance. Annual services and weekly and monthly examinations should be done to know if the unit is in good working condition. Calibration of the unit should also be done since it is a quick and easy task.
Gas has an odor so that a normal person can notice it at a concentration below the explosive range. This level of concentration is between zero point five to one percent. The odor is an indication of a leakage and a report on this must be investigated immediately. If a leak is established, the migration route of the fumes needs to be determined.
Insects such as cockroaches, flies, and spiders like to move to the point of the leakage. This is due to the microbial breakdown around the area. Since they like how fumes smell, busy insect activity around the meter or regulator indicates a leakage. A test should be conducted for confirmation immediately.
Fungus growth around the valve box may indicate a leak. This is because fungi mostly grow around areas without enough oxygen. It is characterized by a white or greyish white color. Such an indication requires investigation with immediate effect using the detection unit. To add on this, any person carrying out the test should only approach a manhole after testing the concentration of oxygen and other gases.
