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 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.
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 portrayed by its unique odor. Due to this, any normal person can notice it with ease when the concentration is below a volatile range. This range of concentration is between zero point five and one percent. Fumes odor is an indication of a leak and therefore any suspicions ought to be looked into immediately. If a leak is noticed, fumes movement should be traced. If there is a likelihood of misfortune, the misfortune needs elimination.
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.
