China Wholesale Helium Chemical Symbol Pricelist – Helium (He) – Taiyu

Technical Parameters

Helium is a rare gas, a very light, colorless and odorless inert gas. It is chemically inactive, and it is difficult to react with other substances under normal conditions. It has stable chemical properties and is dark yellow when performing low-voltage discharge. Helium can be used as a pressurizing agent and supercharger for rocket liquid fuel, and is used in large quantities in missiles, spacecraft and supersonic aircraft; as a shielding gas during smelting and welding, it is used in shipbuilding, aircraft, spacecraft, rockets, and The manufacture of weapons is very important; helium has excellent permeability and is used to cool nuclear reactors, and to detect leaks in rockets and nuclear reactors’ pipelines and electronic and electrical devices; helium has low mass density and weight density, and It is not flammable and can be used to fill light bulbs and neon tubes. It is also an ideal gas for balloons and airships; liquid helium can obtain a low temperature close to absolute temperature (-273°C) and is used to make superconducting equipment; helium is a kind of inert gas, The solubility in the blood is lower than that of nitrogen, so its anesthesia is lower than that of nitrogen. Therefore, helium and oxygen are often mixed as a breathing gas for divers. Helium should be stored upright in a well-ventilated, safe and weather-free place, and the storage temperature should not be higher than 52°C. There should be no flammable materials in the storage area and keep away from frequent entry and exit places and emergency exits, and no salt or other corrosive materials exist. For unused gas cylinders, the valve cap and output valve should be well sealed, and the empty cylinders should be stored separately from the full cylinders. Avoid excessive storage and long storage time, and maintain good storage records.

Application:

Advantages:

1. Our factory produces Helium from high quality raw material,besides the price is cheap.
2. The Helium is produced after many times procedures of purification and rectification in our factory.The online control system insure the gas purity every stage.The finished product must meet the standard.
3. During the filling, the cylinder should firstly be dried for a longtime(at least 16hrs),then we vacuumize the cylinder, finally we displace it with the original gas.All these methods make sure that the gas is pure in the cylinder.  
4. We have existed in Gas field for many years, rich experience in production and export let us win customers’ trust,they satisfy with our service and give us good comment.
