How Much Does Acetylene Cost?
Acetylene is a colorless, flammable gas which has a distinctive garlic-like odor. This gas is composed of a mixture of two hydrogen and two carbon atoms. It is a member of a group of hydrocarbons, known as acetylenes or alkynes. Acetylene is a common component of multiple chemicals, plastics and is commonly used as a fuel for welding and metal cutting torches.
How much is it?
- On average, the price for a swap out of about 60 cubic foot acetylene owner-cylinder is about $70, while you should be prepared to spend about $35 for a 40 cubic foot exchange of an owner tank. The cost is going to depend on where you get the refill and the size of the tank. Similar to propane, it’s going to be a lot cheaper to refill a tank compared to buying a new tank. If you’re going to purchase a new tank, you will want to double the prices above.
- According to some members on PracticalMachinist.com, one member paid about $38 for 100 cubic feet, while another paid $32.
What is going to be included?
- Currently, there are two main methods of manufacturing acetylene. Besides combining calcium carbide with water, this gas can also be produced in a process referred to as thermal cracking. A natural gas, typically methane, is heated in a process which separates the hydrocarbons from the gas. Then, the hydrocarbons are rebounded to form a new substance that has different properties from the original.
- Acetylene is a colorless and combustible gas with a distinct odor. When it is compressed, heated, liquefied or mixed with air, acetylene becomes highly explosive. When used as a fuel for cutting or welding torches, acetylene is normally combined with oxygen to produce temperatures that are higher than possible with acetylene alone.
- Combustion with oxygen (Oxygen-acetylene torches) attains a flame temperature of 5580 Fahrenheit, releasing 1470 BTUs per cubic foot. The high temperature makes oxy-acetylene torches the only form of welding and cutting torches which are hot enough to melt all types of commercial metals. This high flame temperature allows acetylene to be used in a range of metalworking applications such as cutting, brazing, welding, and soldering.
What are the extra costs?
- Special precautions need to be observed during the production and handling of Acetylene. To properly handle acetylene, you need to also have the related equipment and safety supplies.
- When acetylene must be pressurized and then stored for use in oxy-acetylene metal cutting and welding operations, special storage cylinders are used. These tanks are available in multiple sizes. The cost of a new tank depends on the size of the tank. For instance, a new, 40 cubic foot tank retails for about $75.
Tips to know
- Acetylene is extremely volatile since it readily combusts when it gets into contact with oxygen. The properties of this gas are so unstable that even a minute leak can cause serious consequences; therefore, it is very important that acetylene be haisled carefully and stored properly.
- To reduce the potential hazard and decrease its volatility, this gas is typically dissolved in acetone and then stored in specially designed storage tanks with a porous material. These cylinders are normally filled with a small amount of acetone and an absorbent material, such as diatomaceous earth.
How can I save money?
- In general, the price of acetylene per cubic foot capacity will go down as the tank size gets larger. Therefore, you will get a better deal purchasing acetylene in bulk quantities. Some dealers of acetylene offer a reduced price per cubic foot when a customer leases a tank from them. For the leased tanks, it is much preferable to deal with a dealer that prices by the cubic foot rather than the cylinder size.
- Call a few dealers in the area to see what they charge. Most shops will be more than happy to give you a quote over the phone.
