Argon is the most abundant rare gas that makes up roughly 1 percent of the earth’s atmosphere and can exist in several different forms – liquid, gas, etc. Some characteristics of liquid argon is that it is odorless, tasteless, colorless, very cold and most importantly, noncorrosive and nonflammable. Being that argon is passive, monatomic, and forms no known chemical compounds, distinct tank materials are not necessary.
The only specification is that a selected material must be able to endure liquid argon’s low temperature however these argon tanks must follow the specifications and parameters necessary to meet ASME (American Society of Mechanical Engineers) or DOT (Department of Transportation) coding for temperatures and pressures involved. Product transportation of argon is commonly in liquid form although the gas form of argon is used most. This is a more cost-effective way of supplying the product.
Liquid argon is considered a ‘cryogenic liquid’ and has a normal boiling point of below -130 degrees Fahrenheit and must be handled very carefully.
