Dissolved acetylene gas 1. Purity 98% c2h2 2. Filling into welded cylinders 3. Welding, cutting, coating acetylene Dissolved acetylene gas Acetylene (c2h2) is not an air gas, but a synthesis gas generally produced from the reaction of calcium carbide with water. It was burnt in "acetylene lamps" to light homes and mining tunnels in the 19th century. A gaseous hydrocarbon, it is colorless, has a strong garlic odor, is unstable, highly combustible, and produces a very hot flame (over 3000&,161;&,227;c or 5400&,161;&,227;f) when combined with oxygen. Acetylene gas purity: >98% Package: 1l-80l acetylene cylinders Delivery time: within 30days after deposit Moq: 200pcs ( 420 pcs/20ft container) Main applications 1. Welding, cutting & coating Acetylen is the most effective and versatile fuel gas; c2h2 enabling manual applications such as welding, brazing, cutting, straightening or any other localised heating process. 2. Laboratories & analysis Acetylene is the fuel gas in atomic absorption spectrophotometry (aas). Welded steel acetylene gas cylinder 40l
