As an accredited Helium [Compressed Or Liquefied] factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.
| Packing | A high-pressure steel cylinder containing 50 liters of Helium [Compressed Or Liquefied], labeled with hazard symbols and safety instructions. |
| Shipping | Helium, whether compressed or liquefied, is shipped in high-pressure cylinders or specialized cryogenic containers. It is classified as a non-flammable, non-toxic gas (UN 1046 for compressed, UN 1963 for liquefied). Proper labeling, secure stowage, and handling precautions are essential to prevent leaks and exposure to extreme cold or pressure. |
| Storage | Helium [Compressed or Liquefied] should be stored in tightly closed, properly labeled cylinders or containers designed for compressed gases. Keep storage areas well-ventilated, dry, and away from direct sunlight, heat sources, and flammable materials. Secure cylinders upright to prevent tipping. Store at temperatures below 52°C (125°F) and protect from physical damage. Isolate from oxidizers and incompatible substances. |
