Aerospace helium leak testing, inc Helium leak detection technology helium leak testing is described as a means of finding leaks in different types of enclosed or sealed systems utilizing helium as a tracer gas Our safe, precise and proven helium leak testing systems and techniques have become staples in the aerospace industry and its development.
This article explains four common helium mass spectrometry leak detection methods—vacuum, positive pressure, vacuum pressure, and backpressure We'll delve into its methods, why helium is the preferred gas for this type of testing, how to perform a helium leak test, its. Learn about their principles, advantages, limitations, and standards to improve sealing inspection efficiency and reliability.
8 methods of helium leak test do you know how many ways to test leaks
(1) spray method ・to detect helium coming inside the test object by spraying helium with a spray gun after evacuating the inside of the test object ・suitable for finding a small leak point, applying to finding a relatively small leak. Helium leak testing is a highly effective and sensitive method used to detect and locate leaks in various types of systems, components, and containers Uncertainty, tolerances, and test uncertainty ratios introduction helium leak detection is used in a diverse range of industries and an equally wide variety of test methods
Common to nearly all, is a need to understand the relative accuracy of a given measurement. Tightening environmental standards together with increasing functional and safety requirements (to protect the environment, to guarantee high safety standards and product reliability, etc.) drive manufacturers to guarantee leak tightness by completing 100% leak testing as part of the production process. Helium leak testing is an indispensable procedure that plays a critical role in various industries, from aerospace and automotive to medical devices and energy sectors
