Helium is a chemically stable, non-flammable noble gas used in a range of industrial and technical applications. Gas purity grade, container type, equipment compatibility and supply terms should be assessed for each product. Although helium is non-flammable, it can displace oxygen and create an asphyxiation hazard in enclosed or poorly ventilated areas.
Helium cylinder options may be considered for applications such as laboratory work, leak testing, and balloon filling. Gas purity, filling pressure, container type, and supply terms should be verified for each product.
Cylinder bundle and manifold options may be considered for industrial applications with high helium consumption. Flow rate, pressure, and backup requirements should be determined according to project needs and equipment specifications.
Helium may be used with argon in shielding gas mixtures for certain MIG and TIG welding applications. Helium content can influence arc characteristics and heat input. Weld penetration, porosity, welding speed and preheating requirements depend on material, equipment and process conditions. Suitable gas mixtures and available supply options should be verified for each product.
Technical Warning and Safety Standard: Helium is not toxic or flammable. However, helium accumulation in unventilated areas can lower oxygen levels and cause asphyxiation. Inhaling helium gas for fun is extremely dangerous as it suddenly depletes oxygen in the lungs, potentially causing permanent damage or sudden loss of consciousness.
