What are the transportation requirements for high-purity helium?
Helium High purity helium
High-purity helium is a gas with ideal gas characteristics, making it highly suitable for low-temperature vapor pressure thermometers. High-purity helium has low mass and weight density and is non-flammable. It can be used to fill lights and neon signs, and is an ideal choice for balloons and airships. Liquid high-purity helium can be obtained at temperatures close to (-273°C) and is used in the manufacture of superconducting equipment. High-purity helium is an inert gas. Its solubility in blood is lower than that of nitrogen, so its anesthetic effect is lower than that of nitrogen. Therefore, you will notice that high-purity helium is often mixed with oxygen and used as the current breathing gas for divers.

The second point is that the packaging of high-purity helium is also crucial. High-purity helium is typically stored in high-pressure cylinders. The cylinders are gray in color and marked with the green word "High-purity Helium". The filling of high-purity helium should comply with the provisions of the national standard GB14194. Packaging and storage are hazardous in China. According to its performance classification, it is categorized as a Class 2.2 non-flammable gas. Currently, the labeling of hazardous substances in China is also crucial for the storage and transportation of high-purity helium. High-purity helium is non-corrosive and can be stored in any common material at room temperature. It is made from copper, aluminum, and stainless steel at low temperatures. We recommend storing it as both a gas and a liquid. The cylinders should be stored in a cool, air-conditioned warehouse. The temperature should not exceed 30°C. Keep away from sources of fire and heat, and avoid direct sunlight.
High-purity helium can be transported through pipelines or directly through delivery-type storage tanks with capacities ranging from 1L to 30m3. In liquid high-purity helium, it is used for transportation and long-term storage in liquid high-purity helium transport tanks or fixed tanks, typically with capacities ranging from 100-500L. High-purity helium should be stored upright in a well-ventilated, safe, weather-resistant area or where the temperature does not exceed 52°C. The storage area should be free of flammable materials, frequent access and emergency exits, salt, or other corrosive substances. Close the lid and outlet valve of unused cylinders, and store empty and full cylinders separately. Avoid excessive and long-term storage, and maintain good information storage.
