Helium (He)

Helium is widely used in leak detection because it is a very light and inert gas. It can pass through tiny leaks that other gases may not detect easily. Industries use helium for checking pipelines, tanks, pressure vessels, refrigeration systems, valves, and sealed equipment.

Laboratories, universities, and research institutes use helium in gas chromatography, scientific testing, controlled experiments, and analytical instruments. Its stable and non-reactive nature makes it useful where clean gas performance and accurate testing results are required.

Helium is used as a shielding gas in welding and other industrial processes. It helps protect the welding area from contamination and supports cleaner results, especially in applications involving stainless steel, aluminum, and specialized metal work.

Helium is commonly used for balloons because it is lighter than air and allows balloons to float. It is widely used by event companies, decorators, and commercial users for celebrations, promotions, and display purposes.

Helium is non-flammable and non-toxic, but it should still be handled carefully because it is stored under pressure. Cylinders should be kept in a ventilated area, secured properly, and kept away from heat. Helium should never be inhaled, as it can reduce oxygen intake and cause serious health risks.
