WebUsing helium gas realizes detection of minute leaks. Why helium gas is used for leak test. ・Only 5 ppm of helium gas exists in the atmosphere. It is less affected by the background of test environment. ・Helium is safe inert gas without toxicity and explosiveness. ・Because of its small molecule size, helium can penetrate through leaks easily. WebThe helium leak test is a measurement method that uses a leak detector to detect leakage from a change in helium partial pressure in a vacuum. In contrast to other inspection methods, which determines by volume, pressure, degree of vacuum, the helium leak test obtains High sensitivity and high accuracy without depending on skills of operators.

HELIUM LEAK TEST IN LINE: ENHANCED RELIABILITY FOR HEAT

WebThe pressure decay test can guarantee leak detection between 10 -2 mbarl/s and 10 -4 mbarl depending on the unit and on the cycle configuration. It is particurarly indicated for testing of hydronic units and on cooling circuits as pre filtering station for detecting gross leaks or as substitute of water bubble test. Web20 mrt. 2007 · We spec helium leakage testing any time we're dealing with hydrogen or seriously toxic materials. Even a carefully-prepared hydrotest can be insensitive to leakage due to trapped air. Depending on your atmospheric conditions, the leakage water might be evaporating as fast as it's leaking, which also makes it tough to detect. murpark fachl

There are a couple of methods that are widely recognized: a. vacuum method (sometimes known as an "outside-in leak"), where the direction of flow is into the test object; the pressure inside the test …

Web15 jan. 2015 · Helium leak testing offers several advantages such as sensitivity (10-5 to 10-7 cc/sec), leak rate measurement, ability to seal leaks as soon as identified and ability to perform leak testing during normal plant operation. However, several disadvantages to helium leak testing exist, including: The results are operator dependent. Web24 mei 2024 · Helium Leak Testing. Helium being the smallest inner particle that exists, it’s used to detect leaks down to 10-11 mbar L/s. Therefore, its low mass, low background levels and the fact that it’s non-reactive and available at low costs represent other reasons for helium vacuum leak testing to be one of the most preferable options.
