Acetylene Tank, Cylinder & Bottles
Acetylene stored in acetylene tanks is mostly dissolved.
DSW Industry provides various acetylene tanks and bottles in multiple styles and sizes.
Therefore, they are stored at lower pressure. The cylinders must be stored upright with valve caps on because they are potentially explosive.
With our extensive expertise, we possess a wealth of experience in developing gas cylinders and cryogenic tanks. We can process these products according to your specific requirements, including specifications and quantities.

Testing Report of acetylene gas bottles


What is Acetylene?
Acetylene is a colourless, pungent-smelling hydrocarbon gas with an intense flame.
Used mainly for welding and cutting applications (oxy-fuel welding or gas cutting), acetylene produces the hottest flame of all the gases available today.
