40L Acetylene Cylinders

Acetylene Cylinders, Acetylene Bottles- Manufacturer & supplier

DSW offers durable acetylene cylinders, bottles, and tanks in various sizes with acetylene gas for a wide range of industrial applications.

Acetylene cylinders must be filled with acetylene, which is dissolved in acetone and absorbed by a porous calcium silicate mass.
The spongy mass has been designed to prevent decomposition, which could lead to a volatile and hazardous condition if left unattended—store acetylene bottles in a vertical position to avoid unwanted reactions or leaks.

Acetylene gas bottles are commonly used in welding and cutting applications. The gas is highly flammable and produces a high-temperature flame, making it ideal for welding and cutting through metals. The automotive industry also uses acetylene gas bottles for welding and repair work.

It comes in various sizes, from small portable cylinders to larger industrial cylinders.
The most common sizes for portable cylinders are the B (40 cubic feet) and MC (10 cubic feet) sizes, while industrial cylinders can range from 60 cubic feet to over 300 cubic feet.
Choosing the appropriate size cylinder for your specific needs and handling and storing them safely is essential.
