The helium tank is a non-refillable steel cylinder that complies with national standards. Classified as a Class DR4 (now designated as Class B3) special gas cylinder product, it is primarily intended for use in non-professional household and personal settings. The product features a single-use valve design that ensures it cannot be refilled, offering high safety, ease of operation, and excellent portability.
The helium tank is filled with the inert gas helium (chemical formula He) and is suitable for balloon decorations at events such as weddings and banquets, thereby eliminating the flammability risks associated with hydrogen gas. The product must be stored in a cool, well-ventilated area where the ambient temperature does not exceed 55°C; during transport, care must be taken to prevent damage from impact. Operation should be performed by an adult; strictly prohibited actions include striking the cylinder's rupture disc or attempting to refill the cylinder independently.
