Product Introduction:
English name: Helium
Molecular formula: He
Product purity: 99.9%
Pressure: 10mpa·, 13.5mpa
Packing instructions: 8L, 40L high-pressure carbon steel bottle
Filling volume: 1 cubic meter, 5.5 cubic meters
CAS NO.: 7440-59-7
Application areas:
Industrial helium is generally used for cryogenic technology, superconductivity, vacuum balloons, welding, and leak detection
Helium is mainly used in the following industries: aerospace/diving/inflatable balloons/electronics (leak detection)/optical fiber. Helium generally acts as a protective gas in arc-based welding. Due to its inactive chemical properties, it can isolate oxygen and nitrogen from the outside to prevent adverse effects on the molten metal. Only gas welding, which uses acetylene to burn in oxygen to generate high temperatures for welding, uses oxygen.
