what is inside a acetylene tank

by Grady Reilly Published 2 years ago Updated 2 years ago

Acetylene cylinders do not contain compressed or liquefied acetylene; instead they contain acetylene gas dissolved in acetone that is absorbed onto a porous mass within the cylinder. The porous mass inhibits the decomposition reaction, providing time for emergency action in the event of a mishap.

How much does it cost to fill oxygen and acetylene tanks?

What are the costs of filling acetylene and oxygen tanks? Pricing to fill your acetylene and oxygen tanks will vary based on tank size, with larger tanks being cheaper per cubic foot. Your smallest 10 cubic foot tank will cost around $20, #4 tanks at $80, and #5’s upwards of $120.

What is inside acetylene cylinder?

What is inside of an acetylene tank? All acetylene cylinders contain a porous honeycomb material called a monolithic mass. They also contain a solvent (acetone) which is absorbed by the porous mass. The acetylene dissolves in the acetone and holds the acetylene in a stable condition. The cylinder features a copper-alloy valve for controlling the gas flow.

Why do Acetylene cylinders need to be stored upright?

When in use, acetylene cylinders should always be kept in upright position. Otherwise, acetone liquid will be drawn from the cylinders with the gas if they are kept horizontally, resulting in significant leakage of acetone liquid will result. Note: Oxygen and acetylene gas cylinders are commonly used in construction sites for gas welding.

What is inside an acetylene?

All acetylene cylinders contain a porous honeycomb material called a monolithic mass. They also contain a solvent (acetone) which is absorbed by the porous mass. The acetylene dissolves in the acetone and holds the acetylene in a stable condition.

Can an acetylene cylinder explode?

If a cylinder filled with compressed acetylene gas is exposed to a flashback, starts to warm up or vibrate, or if such a cylinder was involved in a fire, its contents may have begun to decompose. This process can become self-sustaining causing the cylinder to explode, in some cases hours after the initiating event..

What is the porous filler material inside an acetylene cylinder soaked with?

Common acetylene cylinders are different from all other cylinders in that they contain a porous filler material and a solvent (acetone or dimethylformamide, DMF).

What is the chemical in the acetylene tank helping it stay safe?

Being chemically unstable, it can even decompose at room temperature if above 15 PSIG. Therefore, acetylene is compressed into a cylinder that has an inert, porous mass made of a calcium-silicate. This mass is saturated with acetone to help absorb the acetylene.

Is it OK to lay down acetylene bottles?

Do not lay acetylene cylinders on their sides. If an acetylene tank has accidentally been left on its side, set it upright for at least one hour before it is used.

Can you smell acetylene?

Acetylene is a colorless and odorless gas. Commercial grade Acetylene may have an Ether-like or garlic-like odor.

Why is there a liquid in the acetylene tank?

Advantages of Acetoning Acetylene Gas Here are a few reasons why acetylene should be stored in liquid acetone: It helps stabilize the acetylene keeping it from reacting with oxygen. Since pure acetylene cannot be pressurized without causing an explosion, it is mixed in acetone to reduce the pressure.

Can I put propane in an acetylene tank?

You WILL need to change your Acetylene Regulator to a Propane type (including for Propylene). You WILL need to change your Acetylene Hose to a Propane Hose (including for Propylene). You will need to check the label on your Flash Arrestor, if it says “Fuel”, it's OK to use with Propane & Propylene.

Can you use acetylene without oxygen?

That is carbon and hydrogen. And in doing so, it starts to release heat. In fact, it can release enough heat that it causes the remaining acetylene to ignite even though there's no oxygen present! This makes acetylene nearly unique in that it doesn't require oxygen to burn.

What happens if you breathe in acetylene?

The symptoms of acetylene inhalation include dizziness, headache, fatigue, nausea, vomiting, tachycardia and tachypnea [2]. Exposure to a high concentration of acetylene may result in a loss of consciousness and death [1] . ... Acetylene is a colorless gas commonly used for welding.

Can you put argon in a acetylene tank?

Absolutely not. Those cylinders are made with different sized orifices and threads to avoid exactly what you propose.

Is acetylene harmful to humans?

General toxicity The principal toxic effect of exposure to acetylene is asphyxiation as it displaces oxygen from the air which results in hypoxia. Symptoms of exposure include dizziness, headache, fatigue, tachycardia, tachypnoea, nausea and vomiting.

What are the materials used to make acetylene?

More on the acetylene cylinder materials.#N#"Granual Masses#N#Numerous materials have been proposed for the making of porous mass in#N#granular or powder form, either alone or as mixtures sometimes with special#N#control of grain size; they include kieselguhr, charcoal, cork, active carbon, #N#pumi ce, silica gel, peat, wood or cellulose, alumina, magnesium compounds ,#N#elder pith, horn meal, cofferdam, meerschaum, sawdust, brick, etc. Kieselguhr#N#has been proposed as bonded into granular form by melamine resins, or#N#carboxy-methylcellulose.#N#Filling cylinders with these non-coherent substances is an easy matter, but most#N#of them suffer from the disadvantage that during use they gradually settle and so#N#no longer fill the cylinder completely, with the result that they have gradually been#N#abandoned in favor of the coherent substances."

What is the porous mass of a cylinder made of?

used in a large number of cylinders, was developed in 1901. It consists of a. special concrete made of pieces of charcoal and a cement made from kieselguhr, asbestos, and zinc oxychloride.

What Sizes Do Acetylene Tanks Come In?

Acetylene tanks come in up to 10 sizes. Going from the shortest to the tallest, they include the following:

What color is an acetylene tank?

Acetylene tanks are maroon-colored, and they come with a copper-alloy valve for regulating gas flow.

How Big Is a Size 3 Acetylene Tank?

A Size 3 acetylene tank is one of the smaller-sized acetylene tanks. It is 30 inches tall, has a diameter of 7 inches, and weighs an average of 41 pounds. The Size 3 acetylene tank has a maximum gas capacity of 75 cubic feet.

How Much Does an Acetylene Tank Cost?

While you might be able to get an MC acetylene tank for around $50, the larger-sized tanks like the Size 5 tank, the WTL, and the WK can cost as much as $300.

How tall is an 8tulip tank?

Also, the 8TULP tank in Canada is homologous to a US Acetylene B tank. But while the 8TULP tank is 19.8 inches tall, the Acetylene B tank is 19.5 inches tall. The diameter of an Acetylene B tank is around 6.1 inches, while that of the 8TULP tank is 6 inches.

How many cubic feet is a MC acetylene tank?

The maximum capacity an MC acetylene tank should contain is pegged at 10 cubic feet.

Which acetylene tank has the highest capacity?

Interestingly, neither the WK cylinder nor the Size 5 cylinder has the highest capacity. The WTL cylinder has the highest maximum gas capacity amongst all the acetylene tank sizes we mentioned above.

Why is acetylene dissolved in acetone?

Therefore, it is dissolved in acetone to make it stable at the pressures encountered in a welding cylinder. The cylinder is full of a porous material which absorbs the acetone/acetylene solution.

How long should you let an acetylene cylinder stand upright?

It's true that if you've laid one down, you have to let it stand upright for awhile before using it. Most safety standards I've seen say somehting like "If an acetylene cylinder has been stored in a non-upright position, it should be stored upright for 30 minutes prior to use."

Can you transport acetyline horizontally?

I normally get argon, tri-mix and sometimes oxygen and I know this is fine for these. The question is with acetyline, my welding supply place told me that it is OK to transport acetyline horizontally as long as you return it to the vertical position for at least as long (time-wise) as it was horizontal.

Can you mount acetylene bottles vertically?

That would probably be OK, but acetylene bottles are so short that there is no reason not to mount one vertical.

Is C2H2 gas unstable?

No, it's a good question - and I don't know for certain. I'll take a guess at it though... I think it's an issue of relative volume. The C2H2 gas coming up through the cylinder valve and into the high pressure side of the regulator has a very small volume, and the energy stored in that small mass of gas is probably not enough to cause instability.
