Pointers On Doing A Helium Leak Test
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 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 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.
