The lifespan of oxygen and acetylene tanks depends on a few factors such as how frequently they are used, how they are stored and how they are maintained.
In general, oxygen tanks can last for 10 to 15 years on average if used and stored properly. The same goes for acetylene tanks, which can last for an average of 15 years. However, regular checks and maintenance must be done to ensure the safety of tanks, particularly for oxygen and acetylene tanks.
Even if oxygen and acetylene tanks pass their expiration date, they must still be checked and tests must be done to make sure they are still safe to use. Furthermore, tanks should always be stored in cool, dry places and away from any heat sources, fire or combustibles to prevent any accident or explosion.
Therefore, while oxygen and acetylene tanks may last between 10 and 15 years if stored and used properly, it is important to keep them well maintained and tested regularly to make sure they’re safe.

How long are welding oxygen tanks good for?
Welding oxygen tanks are typically good for 5-15 years before they need to be inspected or replaced, depending on their usage. Inspections should be conducted annually to determine the tank’s safety and use status.
If the tank is used regularly, it is recommended that the user replace the tank after 5 years. Tanks should also be tested for integrity every 10 years, regardless of usage. Signs of corrosion, fading paint, and leakage should all be checked.
If a tank is determined to be welded wrong or pressurized above its rating, it should be replaced immediately. Because of the potential fire hazards and other dangers associated with malfunctioning tanks, users should always ensure that their tanks are in accordance with safety codes and regulations, and take the necessary precautions to prevent any malfunctions.
How long will a 10 cubic foot acetylene tank last?
How long a 10 cubic foot acetylene tank will last depends on a variety of factors, such as the weld size and the amount of gas used each minute. A rough estimate of a 10 cubic foot tank lasting approximately between 10 and 20 hours of welding at a rate of 1 cubic foot per hour can be made.
Since this is a general estimate, it is important to keep in mind that actual performance may vary based on a number of factors. As a result, it is best to use an acetylene consumption chart from the manufacturer of the tank to get an accurate estimate of how long the tank will last for the specific welding application.
Additionally, it is important to regularly monitor and inspect the tank for any leaks or pressure drops, as these could further affect the overall length of time the tank will last.
How often do welding tanks need to be recertified?
Welding tanks, or cylinders, must be recertified or “hydro-tested” once every five years in accordance with Department of Transportation (DOT) standards. It is important to have them recertified to ensure that the tanks remain safe for use.
The recertification process involves testing the tanks for structural soundness and integrity by filling them with water or specialised liquid and then pressurising the cylinder with compressed air. The test results are checked against the tanks’ original specifications and any changes or defects that might have occurred over time.
The process should be performed by a certified and qualified technician who is experienced in hydrostatic testing. Tanks that fail this test are subject to immediate rejection and must be taken out of service until they pass the test and are recertified.
It is important to maintain the proper certification status of welding tanks to ensure safety, longevity of use, and compliance with DOT standards.
How do I know if my oxygen tank is expired?
It is important to check the expiration date on an oxygen tank to ensure that it is still safe to use. You can typically find the expiration date on the outside of the tank, near the serial number and/or other tank markings.
It is also important to check the manufacturer’s website or the oxygen tank’s documentation to find out if the device is still valid and meet the safety requirements. Additionally, regular maintenance checks of both the tank and devices involved with using the oxygen tank are recommended to detect any potential problems before using a tank.
Signs that a tank may be expired, such as changes in appearance or illegal markings, visible corrosion, denting and leakage, should also be checked by a professional if present. If an oxygen tank is expired, it is recommended to replace the tank with a new one.
Does acetylene have a shelf life?
Yes, acetylene does have a shelf life. Generally speaking, acetylene should never be stored for over 6 months, although for solely technical and medical uses, it can be stored for up to 1 year. It is important to store acetylene in a cool, dry and well-ventilated area, such as a gas cylinder cage, and to ensure the valve of the cylinder is kept closed whenever possible.
Additionally, if the acetylene is being stored in a cylinder, it’s important to note whether it is acetone or sulpher-dioxide based and store it with the corresponding solvent, as mixing them can cause detrimental physical and chemical changes.
The cylinder should also be kept away from any sources of ignition, as well as any direct sources of heat or cold. Finally, while acetylene doesn’t react with other materials, it’s always important to store it properly, as it can still pose preservation issues.
Can old acetylene tanks be refilled?
Yes, old acetylene tanks can be refilled. However, it is important to check the condition of the cylinder before attempting to do so. The tank should be inspected and tested by a qualified professional to evaluate if it is safe to refill, using a hydrostatic pressure test or visual inspection.
The interior should also be cleaned and any damage to the cylinder repaired before refilling can take place. Once it has been determined safe to refill, the acetylene tank can be filled using the proper equipment and materials.
It should also be labeled with its new expiration date, which may be up to five years from the date of the refill. Proper safety and operating procedures must be followed when refilling an acetylene tank, and it is generally recommended that those who are inexperienced with the process seek help from a licensed professional.
What can I do with old oxy acetylene tanks?
When it comes to disposing of oxy acetylene tanks that have been used to store oxygen and acetylene, there are two different methods that you can use, either refurbishing the tanks or recycling them.
Refurbishing the tanks involves professionally inspecting the tanks, then disposing of any material that does not meet safety standards, such as old hoses and fittings. The tanks are then tested for pressure and, if and when necessary, reconditioned and repainted.
The company performing the refurbishing will provide a certificate of compliance, ensuring that your tanks are safe for future use.
The other option is to recycle the tanks. Many tank recycling companies can provide pick-up services so that you don’t have to transport the tanks yourself. Before they arrive, make sure the tanks are empty and thoroughly purged of residual oxygen and acetylene to prevent any accidents.
During the recycling process, the tanks are completely deconstructed and the material is sorted into scrap metal, waste oil, plastic and other materials. The materials are then separated for disposal through either direct reuse or for use as a raw material for other industrial processes.
Ultimately, the recycling process helps keep these tanks out of landfills and in the hands of those who can put them to better use.
Is acetylene more expensive than propane?
The answer depends on several factors, such as where you purchase the fuel, the market price of the fuel, and your geographic location. Generally, acetylene tends to be more expensive than propane, as it is more difficult to store and transport due to its explosive nature.
Additionally, acetylene is not as widely available as propane, meaning it is more expensive to purchase. Propane, on the other hand, is much easier to handle than acetylene, and therefore is more widely available.
Prices of the fuel can vary widely depending on the company supplying the fuels, and the time of year. It is best to check prices of both propane and acetylene before making a purchase to be sure you’re getting the best deal.
Why use propane instead of acetylene?
Propane can be a better choice than acetylene when it comes to welding or cutting metal. This is because it runs cooler than acetylene, making it easier to work with and helps to prevent warping of the metal being welded or cut.
Additionally, it produces less hazardous gasses, making it a safer choice. Propane produces less soot when compared to acetylene, resulting in less cleanup and less discoloration of the metal being welded or cut.
And finally, propane is more portable, making it easier to use in remote locations or in hard-to-reach areas. All of these advantages make propane a favorable choice compared to acetylene when it comes to welding or cutting metal.
Can I substitute propane for acetylene?
No, you cannot substitute propane for acetylene. While both propane and acetylene are fuel gases, they can’t be used interchangeably. This is due to the fact that propane and acetylene burn at very different temperatures.
While acetylene is the hottest burning commonly used fuel gas and can reach temperatures of 5600°F (3100°C), propane is much lower at 3482°F (1925°C). As a result, propane will not be able to reach the temperatures necessary to perform certain welding or cutting tasks.
Therefore, while propane can be used for some heating, soldering, and pre-heating operations, it must not be used in place of acetylene for welding or cutting operations.
How much hotter is acetylene than propane?
Acetylene is significantly hotter than propane as it has a much higher flame temperature. Acetylene has a flame temperature of 3,400 to 3,600 degrees Celsius or 6,152 to 6,552 degrees Fahrenheit, while propane has a flame temperature of 2,060 degrees Celsius or 3,717 degrees Fahrenheit.
Additionally, acetylene produces enough heat to melt metals such as iron, aluminum, and bronze, and can weld up to 18mm depending on the mixture. On the other hand, propane’s flame temperature is too low to be used for welding, though it is still widely used as a fuel for welding torches in conjunction with oxygen.
Is propane hotter than acetylene?
The short answer to this question is yes, propane is hotter than acetylene. However, the answer is more nuanced than that, as it depends on the specific conditions under which each gas is burned, such as the pressure and flow rate.
Under the same conditions, propane tends to reach higher temperatures than acetylene as it has more energy per molecule and is more energy dense. The maximum flame temperature on propane is approximately 3,590°C, while the maximum flame temperature of acetylene is 3,400°C, making propane about 8% hotter.
Moreover, the flame of propane is larger and brighter than the flame of acetylene. Additionally, the auto-ignition temperature of propane is much higher than that of acetylene, meaning propane is much less likely to ignite unintentionally.
All of these reasons make propane hotter than acetylene.
What are the disadvantages of acetylene?
Acetylene has a number of disadvantages that should be kept in mind when considering its use. The flammability and explosive nature of acetylene makes it a difficult fuel to use, and it must be handled very carefully.
The fuel also produces carbon dioxide and soot, leading to air pollution when used. Acetylene must be stored under pressure in special gas cylinders, and must be constantly monitored because it has a tendency to leak, which can be dangerous.
The gas has a high ignition temperature, so the fuel is not likely to spontaneously ignite without a spark from an external source. Acetylene is also highly expensive and will require a significant investment to purchase and maintain.
Lastly, acetylene is not readily available in all areas and may be difficult to purchase.
What gas is hotter than propane?
Acetylene gas is hotter than propane gas when in use, typically reaching maximum temperatures over 6,300 degrees Fahrenheit. Though it often requires a higher pressure to be used, it typically produces a hotter and faster flame than propane.
Oxy-acetylene torches are commonly used by welders and offer high heat output in comparison to propane torches, making them effective for cutting and welding. Additionally, MAPP gas is another fuel often used for welding, which is also hotter than propane.
It has a temperature around 4350 degrees Fahrenheit and burns hotter than propane by 30%. Hydrogen gas is also hotter than propane and is the lightest of all the gases, making it easier to combust, however it is also the least stable and potentially more dangerous to use.
