Helium is used for many purposes that require some of its unique properties, such as its low boiling point, low density, low solubility, high thermal conductivity, or inertness. Of the 2008 world helium total production of about 32 million kg (193 million standard cubic meters) helium per year, the largest use (about 22% of the total in 2008) is in cryogenic applications, most of which involves cooling the superconducting magnets in medical MRI scanners. Other major uses (totalling to about 78% of use in 1996) were pressurizing and purging systems, maintenance of controlled atmospheres, and welding. Other uses by category were relatively minor fractions.

Helium is colourless, odorless, tasteless, non-toxic, inert, monatomic gas that heads the noble gas group in the periodic table. Itsboiling and melting points are the lowest among the elements and it exists only as a gas except in extreme conditions.
Helium is the second lightest element and is the second most abundant element in the observable universe.
Usages:
1. Helium is used as a shielding gas in arc welding processes on materials that at welding temperatures are contaminated and weakened by air or nitrogen.
Firefighter protective Clothing: 2019 models:
Clothing outer fabric: The use of 210g arylon three anti-fabric, which not only has a permanent flame retardant, high temperature resistance, acid and alkali resistance and other properties, and its strong performance is very excellent, with high heat insulation, permanent flame retardant, high strength, anti-cutting, acid and alkali resistance, arc resistance and other characteristics, improve the overall protection performance of clothing, clothing overall main technical parameters are much higher than the industry standard and bidding technical requirements. The fire retardant performance of the firefighter\'s fire extinguishing suit: the warp and weft continuous burning time is 0s, the warp and weft damage length is less than 51mm; Breaking strength: longitude and latitude 1000N; Tear strength: longitude and latitude 120N; Moisture resistance 3, thermal stability: change rate 1.0%; Color fastness: Color resistance 4, water friction resistance 4.
Waterproof breathable heat insulation layer: aramid non-woven fabric and flame retardant PTFE film, gram weight 180g/m2. It can not only prevent the infiltration of water and other general liquid chemicals, but also discharge a large amount of hot gas generated in the body during fire rescue in time. The fabric has hydrostatic pressure & 50kPa, moisture permeability 5439g/m2/24h, oil-repellent performance 3, and thermal shrinkage 1%.
Comfort layer: The use of intermediate arylon fiber and flame retardant viscose fiber blended, gram weight 125g/m2, flame retardant performance, thermal stability and other properties are very good.
