Acetylene (also known as dissolved acetylene) is the hottest and most efficient of all the fuel gases. Our acetylene gas cylinders offer customers low ignition energy, a localised flame and reduced wasted heat. When acetylene is used in cutting processes, improved cut quality, higher cutting speed, and faster cut initiation time are achieved. These advantages can greatly improve productivity. Acetylene is a highly versatile fuel gas, making it the gas of choice for processes including cutting, gas welding, flame heating, flame gouging, flame straightening and brazing. Customers buying acetylene from us receive industry-leading standards of safety. Our fuel gases are fitted with a left-hand cylinder valve to provide additional safety benefits. Acetylene is provided in a specially designed gas cylinder to prevent decomposition and ensure maximum longevity.
Acetylene can ignite and burn instantly from a spark or piece of hot metal. It can form explosive acetylide compounds with some metals, most notably copper, silver and mercury. Please note: copper alloys containing less than 65% copper and silver solder containing less than 43% silver are considered safe. Hoses used with acetylene are coloured red and are designed to resist acetone. For this reason, other fuel gas hoses must not be used. For a full list of materials that are not allowed or are recommended only under certain conditions, please consult BCGA Codes of Practice CP5 and CP6. As with any gas, there are some hazards, and you can find out more about the safe handling and risks of acetylene in our helpful acetylene guide.
