We produce both industrial and instrument grade acetylene gas in Australia, which we manufacture to the highest standards. Industrial acetylene is used in a wide variety of applications, including flame straightening, heating, hardening and cleaning, oxy-acetylene cutting, thermal spraying, welding, gouging and brazing. Instrument grade acetylene is primarily used in atomic absorption flame spectrometers.
If you have any questions about the acetylene gas we supply in New Zealand, please do not hesitate to contact us by phone or email. If you would like to place an order, you can open an account with us online or contact your Coregas customer service team for pricing and delivery information in your area.
Customers with an account can purchase direct delivery from Coregas, or through our national distribution partners. You can also purchase acetylene gas through our independent distribution partners including Bunnings for our Trade N Go range. Click here for our store locator.
Coregas account customers can choose their preferred method to place an order. Coregas offers online ordering via our website, or our New Zealand based customer service team as well as through email.
An acetylene tank should always be stored upright and secured in place with chains or other suitable restraints. This is because acetylene gas is mixed with a solvent (usually acetone) to prevent decomposition, which can lead to explosions. Storing the cylinder tanks upright ensures the gas does not separate from the solvent. Additionally, the distance between acetylene cylinder tanks and other cylinders, goods and features should be to Australian Standard 4332-2004 in order to ensure safe storage.
Your acetylene usage will depend on the specific application but for safety reasons, it is not advisable to use flow rates greater than one tenth of the cylinder tank’s capacity. For example: with a single cylinder tank that holds 9.3 cubic metres, your flow rate should not exceed 0.93 cubic metres per hour. Please contact us if you need more help with your calculations.
Acetylene gas can burn in normal air without a supply of pure oxygen but for heavy duty heating applications, an oxy-acetylene mix is needed to reach the required flame temperature.
Due to the potential for dangerous reactions when mixed, oxygen and acetylene cylinder tanks should never be stored together. Please refer to Australian Standard AS 4332-2004 for additional information on storage for acetylene.
An oxy-acetylene gas mixture is capable of producing a flame with a temperature of around 3,100 degrees Celsius, which makes it an excellent choice for industrial steel welding applications in Australia, New Zealand and across the globe. Unlike propane, acetylene gas produces a reducing zone when burned in oxygen, cleaning the metal surfaces being welded.
This depends on the required flow rate and usage requirements. Multiply your required hourly flow rate by 10 and this is the minimum acetylene cylinder tank size you will need. For flow rates that exceed our largest cylinder tank size, manifolding several cylinder tanks together may be the best solution.
