About Acetylene cylinders

Acetylene cylinders do not contain compressed or liquidized acetylene; rather they contain gaseous acetylene that has been dissolved into acetone and then absorbed onto a porous mass within the cylinder.

 

Acetylene Cylinders: Welding Equipment

Acetylene is an extensively used gas in welding industry. It is used for both welding and cutting operations. In most fabrications industries, acetylene cylinders are a common sight.
Acetylene, when used with oxygen, produces the highest flame temperature of any of the fuel gases. It also has the most concentrated flame but produces less gross heat of combustion than liquid petroleum gases and synthetic gases.
