$ $ Acetylene Refilling: $2-$50+

Acetylene is a natural, colorless, and highly flammable gas that’s commonly used as a fuel, it’s part of many crucial processes in industries, and it’s a component of multiple chemicals and plastics.

This fuel gas is stored in tanks that people can buy or rent and then refill to use as much as needed.

What Is Acetylene Used For?

According to, the most common commercial uses of acetylene are:

  • Portable Lighting.
  • Welding, Cutting, and Heat Treating.
  • Production of Chemicals.
  • Used in Production of Polyethylene Plastics.

Why Is Acetylene Stored In Tanks?

Acetylene is an extremely volatile natural gas that can rapidly combust when it makes contact with oxygen, which means the proper storage of acetylene is very important to avoid serious consequences.

To avoid any hazards or consequences and decrease its volatility, acetylene is stored in compressed cylinders or tanks that contain a porous filler material and a solvent in which the acetylene is dissolved.

The solvent used, which is atypically acetone, helps decrease the volatility of acetone and allows greater quantities of acetylene to be stored at lower pressures, making it safer to use.

What Sizes Of Acetylene Tank Exist?

There exist many different sizes of acetylene tanks, which are:

Name Size
WQ 70 cubic feet / 7″
WS 100 cubic feet / 8.5″
