What is acetylene?

• Acetylene is a hydrocarbon and unsaturated gas.
• Acetylene consists of two carbons with a triple bond to which each carbide is attached to hydrogen.
• Acetylene is a colorless, odorless, flammable, and slightly lighter gas than air.

Available grades of acetylene:

• Acetylene in both industrial and laboratory grades (Use for atomic absorption devices AA) is available.
• The Industrial acetylene is %95.
• The Acetylene AA is equal to %99.6.

Acetylene storage and transport tanks:

• Although acetylene turns into a liquid under pressure, and refrigeration can easily solidify it.
• it’s due to its high explosive properties for both liquid and solid acetylene, acetylene is transported and stored as a solution in acetone.
• Acetylene storage and transport tanks have a porous sponge that is immersed in acetone solvent.
• This is to prevent the accumulation of acetylene in the liquid phase and compressed form and Also to prevent the possibility of explosion.
• Acetylene in acetone is traded by weight on an industrial scale.
• Acetylene storage tanks are also referred to as the maximum rechargeable weight. Such as 9 pound, 12 pound, 15-pound tanks.

Compatible and incompatible materials:

1. Use of pipes, fittings, regulators, valves, etc. Which is Made of copper and silver or compounds with high levels of copper and silver as well as mercury for acetylene gas due to the possibility of explosion.
2. The use of aluminum, stainless steel, carbon steel as well as polymers of neoprene, Whiton, Teflon, and Kel-F with acetylene is allowed.
3. The use of cast iron fittings is not permitted.
4. The use of rice with less than %65 copper and also nickel compounds for acetylene is allowed under normal conditions.
